Critical Infrastructure

BY MAUREEN McCANN, ASPB President, National Renewable Energy Laboratory

Maureen McCannGlobal agricultural production of rice, wheat, maize, and soybean, crops that together provide over 70% of human calories, was at close to record yields last year, despite the COVID-19 pandemic. Governments recognized growers as essential workers and the food supply chain as critical infrastructure. Early concerns about potential food shortages proved unfounded. Our collective fears for the fragility of our food supply should now be transformed into renewed respect and gratitude for farmers and growers, as for other frontline workers.

A key component of the critical agricultural infrastructure is the up-front investment that governments make in research. In the United States, this investment includes USDA laboratories and land grant universities, which develop technologies relevant to agriculture and give them directly to growers, and the human capital of PhDs trained in fundamental plant biology. Although mechanization, industrialization, and production of synthetic fertilizers have contributed to dramatic crop yield increases over the past 50 years, as plant scientists we can be proud of our discoveries leading to improved seed genetics and accelerated breeding strategies that changed the stature and form of plants in the fields and led to increased grain yields.

It is a remarkable achievement that, on the same land area, U.S. corn production increased from 100 metric tons in 1960 to 367 metric tons in 2020. Soybean production more than doubled, from 20 to 46 metric tons, in the same time frame. However, farmers have not reaped the full benefits of these yield increases, a phenomenon that agricultural economists refer to as the “technology treadmill” (Levins and Cochrane, 1996). Although new technologies contribute to increased production, prices decrease faster as those technologies become widely adopted. The demand for agricultural products is inelastic, leaving farmers with slimmer and slimmer margins of profit.

Almost half of the production cost of an acre of corn is for nitrogen fertilizer. As corn prices rose this spring, fertilizer costs also rose, without any significant increases in the costs of ammonia production. A back-of-the-envelope calculation for gross returns on corn in 1960 comes to $60 per acre. In 2020, corn production yielded about $1,000 per acre. However, adjusting for inflation, in 2020 corn yielded $115 per acre in 1960 dollars. Thus, per acre, the yield has tripled, but the return has barely doubled. For soybeans, yields have more than doubled, but gross returns were the same in 2020 as in 1960, about $50 per acre. As the old joke goes, when the farmer who won the million-dollar lottery was asked how he would use his winnings, he replied, “I’m going to keep farming until it’s all gone.”

In just a couple of decades, agriculture has become data-enabled and technology-intensive. Tractors are guided by GPS, and water and fertilizer are precisely applied according to data collected by soil sensors. Innovations in red and blue light-emitting diodes supply specific wavelengths of light to crops grown in controlled environments. Developing technologies include robotic pickers that sense the color of ripe fruits using machine learning algorithms, robotic harvesters small enough not to damage and compact soils, and drones that can deliver agrochemicals more precisely (King, 2017). The protein transition from animal to vegetable proteins in products such as the Impossible burger, vertical agriculture using closed systems in urban and suburban environments, and weather modification technologies might impact farming in disruptive ways (de Wilde, 2016). But will these innovations, wonderful as they are, simply become additional components of the technology treadmill?

Our challenge, then, is to imagine how plant biology can add value to every plant and bring new acres into production while preserving and increasing yields. We have astonishing new tools in genetics, metabolic engineering and synthetic biology, conservation technology, bioinformatics, and biotechnology. As plant biologists, we have a responsibility to use our talents to future proof all of the species we depend on for food, feed, fiber, fuel, and pharmaceuticals, and to create the critical infrastructure for a successful and equitable plant-based bioeconomy that supports the livelihood of growers and their communities.

In the United States, a long history of policy injustices disproportionately impacted African American farmers, who now number 45,000 (of 3.4 million farmers) compared to 1,000,000 a century ago. Pathways for equal participation both in the lab and in the field need to ensure that the best and brightest can become engaged to ensure the robustness of an evolving agriculture.

A pandemic is one shock to the system. The robustness of our food supply will depend on the resilience of the global agricultural system to a series of future shocks. As the population approaches 10 billion, per capita food consumption is projected to grow 8% to 12% (Ahmed et al., 2020). Arable land and fresh water supplies are decreasing. Agricultural productivity is projected to decline as temperature increases and weather events become more erratic. Almost one-quarter of greenhouse gas emissions come through agriculture, forestry, and land-use change (Ahmed et al., 2020). Worldwide, cattle and dairy cows emit greenhouse gasses equivalent to the total emissions of the United States (Ahmed et al., 2020). Worse, agricultural emissions are heavily skewed to methane and nitrous oxide, much more potent gases than carbon dioxide for global warming.

The agricultural sector must balance food security, nutritional needs, and preservation of biodiversity with the imperative to decarbonize for climate change mitigation. But farmers and growers around the world need to have their livelihoods protected. It’s time for us to step up and support our essential workers.

Enid MacRobbie Corresponding Membership Award

Corresponding Member status is conferred by election on the annual ballot. This honor, initially given in 1932, provides life membership and Society publications to distinguished plant biologists. The following individuals have been nominated this year:

Naomi Ori
Hebrew University of Jerusalem
Naomi Ori is a professor at The Robert H. Smith Institute of Plant Sciences and Genetics in the Agriculture Faculty of the Hebrew University of Jerusalem in Israel. Naomi investigated the mechanisms underlying the plasticity of plant development and patterning, and how plasticity is balanced with developmental stability. Most of her research is dedicated to leaf development and morphogenesis in plants. Naomi’s research contributed some of the first examples of the cross talk between transcription factors and hormones in plant development. Her group identified several factors that affect the balance between morphogenesis and differentiation and showed that transcription factors and hormones such as auxin, cytokinin, and gibberellin interact in coordinating development in both processes. In this regard, Naomi made a substantial contribution to the unravelling of the role of different hormones in shaping leaf morphology. More recently, the Ori group has been engaged in investigating the regulation of fruit development and fruit set.

Naomi has been an ASPB member for years, and she has attended many ASPB meetings.

Martin Gibbs Medal

Jeff Dangl
University of North Carolina, Chapel Hill
Jeff Dangl is awarded the 2021 Martin Gibbs Medal for his outstanding contributions to our understanding of how plants manage interactions with both pathogenic and mutualistic microorganisms. After receiving his PhD in genetics from the Stanford University Medical School, Jeff spent four years as a postdoctoral fellow in the Department of Biochemistry at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, moving to become a group leader in the institute’s Max Delbrück Laboratorium. It was there that he started his program to identify disease resistance loci in Arabidopsis.

In 1995 Jeff became associate professor at the University of North Carolina at Chapel Hill, where he is currently the John N. Couch Distinguished Professor in the Department of Biology and adjunct professor of microbiology and immunology in the School of Medicine; he is also a Howard Hughes Medical Institute–Gordon and Betty Moore Foundation plant science investigator. Jeff is an elected member of the American Academy of Microbiology, NAS, and the German National Academy of Sciences Leopoldina and is a fellow of AAAS. Jeff holds an honorary doctorate from the Hebrew University of Jerusalem and has won many awards, including the ASPB Stephen Hales Prize in 2009.

Jeff has made seminal research contributions to our understanding of the molecular players that define the plant immune system, critical for protecting food crops from pathogens. His work led to the first coherent model of the plant immune system and, in fact, the first use of that term, which is now found in several biology textbooks. Jeff’s work on the mechanism of action of NLR proteins (named for their nucleotide binding and leucine-rich repeat domains) that “recognize” pathogen virulence factors (effectors) leading to activation of successful immune responses has guided subsequent discoveries in the mammalian immune system. Jeff’s discovery that NLR proteins can recognize modified-self molecules led to the guard hypothesis of plant defenses. Jeff has additionally been a pioneer in defining a new research discipline to understand how the plant microbiome contributes to plant growth and productivity, showing that plants specifically recruit, maintain, and balance a taxonomically limited microbiome from native soils.

The Martin Gibbs Medal honors “an individual who has pioneered advances that have served to establish new directions of investigation in the plant sciences.” Jeff has revolutionized our understanding of plant–microbe interactions in ways that have introduced new paradigms across biology.

Stephen Hales Prize

Detlef Weigel
Max Planck Institute for Developmental Biology
Detlef Weigel is executive director of the Max Planck Institute for Developmental Biology. He has made notable discoveries in diverse areas of plant molecular genetics, fostered generations of talent, and through his collaborative network made tools and genetic resources available to colleagues around the globe. Detlef has promoted the plant biology community at the international level through service on numerous advisory and editorial boards, including 10 years as coeditor of The Plant Cell.

Detlef’s early plant work led to direct evidence for long-distance signaling to induce flowering, and his seminal discovery of a microRNA mutant provided the foundational knowledge to enable artificial miRNA technology. He has been a pioneer in exploiting natural genetic variation to understand the adaptive value in plant functions from development to immunity, heterosis, and response to environmental change. His vision of using multiple genome sequences to study genetic variation enabled his studies and formed the basis for widely used resources from the 1001 Genomes Project and online tools that allowed many labs to exploit genetic variation for other research questions.

ASPB’s 2021 Women’s Young Investigator Travel Award Winners Announced

Each year, ASPB, through its Women in Plant Biology Committee, makes travel awards to early career women investigators to attend the Plant Biology conference. The goal of the competitive process that underpins the Women’s Young Investigator Travel Award (WYITA) program is to increase attendance of early career women investigators at the Plant Biology conference by providing travel funds.

Because of the pandemic and its related effects, and to protect the safety and health of our members and community, the ASPB Board of Directors decided to convene Plant Biology 2021 as a fully virtual meeting. Because physical travel will not be necessary, the WYITA has been reframed as a conference attendance award.

Applications are open to scientists from around the world who are within the first five years of their appointment in academic faculty-level positions, government research positions, or industry research scientist positions, as well as to experienced postdocs. Selection is based on the science and quality of the abstract submitted, relative to the applicant’s amount of time as an early career investigator; a statement describing why their attendance should be supported; and financial need.

Seven women—listed here, along with their abstract titles—were selected this year, and each will receive an attendance award to support their participation at Plant Biology 2021.

Congratulations to all of the 2021 WYITA winners!

No. 71—Countless New Ways to Build Your Career Network Before, During, and After Plant Biology 2021

Reason No. 71 is actually many reasons, boiled down to building your professional network. We learn that the best way to network is to do about 15 things before we arrive at a meeting, but who has that kind of time? Instead, most of us rely heavily on the amazing chance encounters and informal networking sessions that typically occur during a conference. These are all the more important in the virtual space, where there is no chance to run into the one person you’ve wanted to meet in the hallway, in the hotel elevator, or (best of all) sitting next to you on the flight to the conference. However, the Plant Biology 2021 platform has risen to the challenge of making your networking opportunities a key and enhanced component of the meeting.

First, 2 weeks before the meeting (beginning July 5), you can set up your profile and list all the areas you are interested in, allowing you to connect with others who have the same interests. And for the next 2 weeks, during the meeting and afterwards, you can communicate with fellow attendees, exhibitors, and speakers.

Because the platform provides you with your own video chat feature, you can invite someone to chat, talk, or just text with you. And if you find enough participants interested in a particular topic or area, you can even set up your own impromptu “hallway” networking session.

Plant Biology 2021 is also structured to encourage conversations with session speakers. All concurrent symposia for 2021 will feature a 30-minute live chat with speakers after their talks, giving you a chance to ask questions or discuss research with presenters in greater depth.

In addition, of course, there will be networking meetings by topic or special interest, as well as several social gatherings.

You can plan on using social media to let folks know you are attending Plant Biology 2021 before and during the meeting. You’ll be able to make comments about the platform and sessions through the inbuilt chat function, as well as on your own and the conference’s social media sites. In addition, you can post reviews of the event and, most importantly, keep up with the new friends and colleagues you meet.

No. 72—Present Your Research

The poster platform for this year’s meeting is simple to use, and it includes some great outreach features. Virtual meetings allow others to see your research 24 hours a day. They can set up appointments, or you can designate your preferred times to meet during the conference. Remember: Posters and all other content are accessible to registered attendees for a full year.

For 2021, there is also an easy-to-use video chat feature that allows you to invite others to see your poster or give a brief overview. You can post the video on any social media platform and invite others to meet with you at a specified time. There will also be organized discussions on poster topics. All this means that this particular conference will offer many excellent ways to highlight your research.

No. 73—Have Fun and Participate in the Scavenger Hunt with Exhibitors

Back for a second year is our well-attended trivia night, hosted by ASPB’s Early Career Plant Scientists Section. But that’s not all—there are many other virtual social events in the planning. And you will want to participate in the scavenger hunt by visiting our exhibitors; there will be daily Amazon gift card prizes, and the grand mystery prize is a good one!

And Finally, No. 74—Group Rates

If you can take advantage of our group rates by signing up with others, not only will you save money, but you can “divide and conquer” by sending members of your group to attend different sessions and workshops! Then afterwards, you can get together in your chat room or networking session and share key insights with your fellow group members. There are group rates for groups of all sizes, and this year you don’t have to all be from one organization, as long as you have at least five people, each with their own email address. Instructions for registering a group can be found on the registration page at

Changing Cultures and Climates: A New Online Resource for Equity, Diversity, and Inclusion

BY JUDY CALLIS, ASPB Past President and JOANNA FRIESNER, Executive Director, and TERRI LONG, Inclusivity Scholars Subcommittee Co-chair, North American Arabidopsis Steering Committee

Changing Climates and CulturesASPB, in partnership with the North American Arabidopsis Steering Committee (NAASC), has created an online hub, Changing Cultures and Climates, for resources aimed at improving diversity in the plant sciences ( The mission of Changing Cultures and Climates is to provide information that supports and promotes equity, diversity, and inclusion in the international plant science community so that it grows to more accurately reflect our larger, global society.

The site is a living collection of impactful literature about culture and gender matters, information about programs and initiatives that focus on increasing and sustaining diversity in plant science, and a safe space to learn more about one another and to discuss topics around equity, diversity, and inclusion that impact our community.

The objectives of Changing Cultures and Climates are

  • to incorporate a safe virtual space for Black, Indigenous, and people of color and other minoritized folk to share experiences and access resources
  • to create a rich and interactive venue that empowers all plant scientists to become better informed to provide resources for actively addressing the impacts of institutional racism on STEM environments, and plant biology specifically.

Visit the Changing Climates and Cultures page on Plantae to find

  • posters for your lab
  • notices of events related to equity, diversity, and inclusion
  • the Front and Center channel—a place to meet colleagues and see highlights on Black, Indigenous, and Latine plant scientists
  • the Adventitious Roots page—information and an invitation to join a safe space Discord server for plant scientists in unsupportive scientific environments based on their ethnicity or race to seek advice, support, or a listening ear
  • the Anti-Racism Toolkit—collections of resources for building a culture based on racial justice to make a better space for all
  • ASPB and NAASC initiatives related to equity, diversity, and inclusion.

As a living hub, we welcome suggestions for additional resources from the plant science community. Please email Katie Rogers at or send submissions on the form at

This is an important initiative for ASPB and NAASC, and we appreciate your engagement, feedback, and input. Many thanks for your commitment to helping our community become more diverse, more welcoming, and more inclusive.

ASPB will be holding a breakfast panel, Building Sustained Commitments to Equity and Inclusion, at the Plant Biology 2021 Worldwide Summit to continue the discussion and convert these conversations into action. In addition, NAASC will hold a workshop at the International Conference on Arabidopsis Research 2021 in June to share brief reports on new activities and partnerships from the past year and provide ample opportunity for you to share your thoughts as part of a lively conversation.

As the Changing Climates and Cultures resource hub grows, we hope to promote change in our community. We also hope to increase our collaboration with additional plant-related societies.

Meet Sabrina Chin, 2021 Ambassador of the Year

Sabrina ChinI’m Sabrina Chin, a research associate at the University Wisconsin–Madison in Simon Gilroy’s lab. I currently work on NASA-funded projects with Simon and Elison Blancaflor, studying gene expression changes in gravity-sensing cells during gravity simulation and the effects of microgravity on the plant cell wall and root hair development.

I received my BS with a double major, one in cell molecular biology and the other in immunology and microbiology, from the Australian National University in Canberra, Australia. I then switched to plant sciences and did my honors studies with Ulrike Mathesius working on RNAi delivery via transgenic roots to parasitic root-knot nematodes. I eventually did my PhD under her guidance on the role of flavonoids in mediating host–parasite interactions during root-knot nematode infection.

Through my honors and PhD dissertations, I began to appreciate the sophistication of parasitic infection in orchestrating essential and basal host responses, particularly those of root-knot nematodes, which infect more than 300 plant species. I realized that to study interactions at that scale, I needed to learn more about bioinformatics and root development. Thus, after my PhD, I worked on Simon’s NASA project on root transcriptomics at Noble Research Institute for my postdoctoral fellowship (our NASA projects were recently transferred to the University of Wisconsin–Madison because of organizational restructuring at Noble Research Institute).

During my PhD studies, I was fortunate to be in the company of great peers and colleagues who offered me opportunities to volunteer for professional societies; I worked with the Australian Society of Plant Scientists and the International Society of Root Research when they organized their conferences in Canberra. Through these experiences, I learned that the plant science community is an anchor for scientists at every stage, particularly students. It was a natural progression for me to continue volunteering by joining the ASPB Ambassador Program when I moved to the United States.

So far, my experience with the ASPB Ambassador Program has been extremely rewarding, and I have enjoyed being able to do interesting nonbench roles. For instance, I was able to help moderate concurrent symposia for Plant Biology 2020 and got to know other ambassadors by doing so. The highlight of my role as an ambassador was writing the Unsung Heroes of Plant Biology article on Marcela Tello-Ruiz published in the January/February edition of the ASPB News. It was extremely rewarding to hear from her that she enjoyed the article and to have created a pedestal for her experiences as a Latina scientist. I strongly recommend to students that they participate in ASPB activities to explore their scientific and nonscientific interests.

I am also privileged to be an early career representative on the Women in Plant Biology Committee and a member of the Equity, Diversity, and Inclusion subcommittee of the Early Career Plant Scientists Section. We are working on producing webinars, a resource hub, and more initiatives to showcase underrepresented scientists.

Finally, I’d like to thank the ASPB Council and staff and the other ambassadors for creating an avenue for me to contribute and learn. I would also like to extend my gratitude to Elison and to dedicate this award to him for being an excellent mentor and encouraging me to participate in ASPB.

Unsung Heroes

Chrislyn Particka

Michigan State University

ASPB Ambassador, Postdoctoral Researcher at Michigan State University

Chrislyn PartickaChrislyn Particka is director of the Michigan State University (MSU) Plant Science Research Greenhouse Facility, where she and her team facilitate the successful greenhouse research endeavors of MSU plant researchers.

When she was a teenager, Chrislyn’s family bought a blueberry farm in Arkansas, which later expanded to growing blackberries, raspberries, apples, and Asian pears. From then, Chrislyn got interested in fruit horticulture.

When Chrislyn was a senior in high school, Curt Rom, professor in the Horticulture Department at the University of Arkansas, convinced her to major in horticulture. At the same time, she also discovered molecular biology and how scientists could make plants glow using a firefly gene. After a summer internship in which she mainly did molecular work, Chrislyn saw the value and the importance of lab work to develop a successful breeding program, but she decided that it was no fun being stuck in the lab when she could be outside instead. From there, she continued her studies in horticulture with an emphasis on fruit breeding. She pursued a master’s degree with John Clark at the University of Arkansas, followed by a PhD at MSU with Jim Hancock, where she studied resistance to a strawberry root disease.

After a 5-year industry experience following grad school, Chrislyn moved to upstate New York and started a job as a coordinator for a USDA Specialty Crops Research Initiative grant led by Tim Martinson on cold-hardy grapes at Cornell University. Chrislyn reflected, “I really thrived in that job, and it was a turning point for me to find this other career path where I could still use my degree and my scientific knowledge while flexing the skills I have in other areas. I realized I was good at research management and this administrative side of science.” Additionally, Chrislyn was actively involved in the outreach component of the project, working directly with growers to help them make their businesses successful by facilitating the delivery of information they needed.

Chrislyn and her family eventually moved back to Michigan, and she joined the DOE-funded Great Lakes Bioenergy Research Center (GLBRC) at MSU as a research coordinator. Although her responsibilities were very similar to the ones she had had in her previous job, the research endeavors were completely different, focusing on the development of sustainable biofuels and bioproducts from bioenergy crops grown on nonagricultural lands. In this role, Chrislyn did a complete overhaul of the GLBRC Research Experiences for Undergraduates program, “which was probably the most rewarding part of that job, and really fun for me—to bring the students in and help them figure out if they wanted to go to grad school or not.”

When Chrislyn wanted to get back to her horticulture roots and felt she was ready for more responsibilities, she transitioned to her role as director of the Plant Science Research Greenhouse Facility at MSU. At the same time, MSU had made great progress to bring attention to the aging condition of the greenhouses and had requested a $20 million capital outlay project from the state of Michigan. “The chance to lead the facility through a major upgrade and a broad-scale improvement was pretty enticing and exciting to think about,” Chrislyn recalled. “MSU was the pioneer land grant college in the United States, and it is really important to me that we don’t lose sight of our roots and how we support farmers. With climate change and everything that is making it harder for farmers to be successful, there needs to be ongoing research to figure out how to raise good crops, and the greenhouse facility plays a part in it.”

Six months into her new role, the pandemic hit. Although the big improvements might not happen for another few years, MSU announced in March 2021 that they would dedicate $4 million to support the greenhouse facility over the next few years. “It is going to make a big difference,” Chrislyn said. “From the large-scale renovation plans I had, I am going to decide what can be done now to benefit the biggest numbers of greenhouse users.”

The facility has remained open and operational during the pandemic, and Chrislyn’s focus has been to help users find space, enable them to collect material and data, and make sure their overall research needs are being met. In the long term, Chrislyn hopes to achieve the complete overhaul of the greenhouses so she and her team can focus on offering more services to facility users. “My hope for this massive improvement of the facility is to make a difference in the quality of research that everyone is able to do, because it is important to me to keep the science that founded this land grant university at its best.”

In her spare time, Chrislyn enjoys baking and cooking, reading, spending time in her yard, and camping—no need for a Wi-Fi connection! The quieter, the better.

Ian Newman

Honorary Research Associate, Biophysics, University of Tasmania

ASPB Ambassador, University of Florida

Ian NewmanIan Newman is an honorary research associate in biophysics at the University of Tasmania ( During his long teaching and research career, he has published widely in the field of plant biophysics, especially on membrane transport and ion flux measurements. He developed the microelectrode ion flux estimation (MIFE), an automated technique for measuring membrane transport such as nutrient uptake by plant roots ( This technology is commercially available and widely used in plant science research.

Ian was born in Sydney, Australia, in 1936. He grew up in Sydney and then Wellington, New Zealand. At the age of 12, his father was appointed to head the Botany Department of the University of Ceylon (now Sri Lanka), so the family moved to Colombo. After a year and a half, Ian returned to Sydney for his high school and undergraduate studies.

He had a liking for mathematics and physics, so he earned his bachelor’s degree in those subjects at the University of Sydney. He
then completed an honors research degree at the University of Tasmania in the biophysics lab under Bruce Scott’s supervision, after which he enrolled for part-time PhD studies and continued working in Bruce’s lab. During this time, he was also tutoring and demonstrating at the physics lab to undergraduate students.

On completing his PhD in 1965, Ian realized that Tasmania was a very lovely place to live, so he settled there. He got married and was appointed a lecturer in medical biophysics to teach basic physics and biology to medical students, beginning a 30-year career as a lecturer and a senior lecturer while continuing with his research in plant biophysics. Essentially, Ian made electrical measurements of plants in a variety of ways and ended up developing MIFE, a noninvasive microelectrode technique automated to measure nutrient uptake by plant roots or any other tissue in a solution. This effort was stimulated in particular by a sabbatical with Bill Lucas at the University of California, Davis, in 1985. After Ian got back to Tasmania in 1986, he continued to work on the design and programming required for good functionality of MIFE, essentially updating what he had worked on while on sabbatical. Ian was supported in these studies by his postdoc, Sergey Shabala, who is now well known in the membrane transport field. Ian retired from teaching in 1996 and continued developing MIFE for diverse applications, especially for the elucidation of membrane functions and for nutrient uptake measurements.

Ian has developed dry age-related macular degeneration, a condition associated with the death of cells in the central part of the eye, leading to blindness. Ian first noticed difficulty reading a section of a poster with small print and low contrast at a conference in 2005. By late 2020, it had become impossible to read unless the text was very large; the limited reading he does now is with the use of peripheral vision.

What got you interested in plant biology in general, and what influences directed you to your specific area of research?
During the early days, my father, a botanist, used to take me along on excursions with his students, where he would explain things happening in nature. In high school, I got interested in physics because of the way my physics teacher used to teach. My love of physics, mathematics, and chemistry and the early influence of my father contributed to my future research in biophysics. During an academic trip to the University of Tasmania, I was intrigued by demonstrations of Bruce Scott’s use of physics in making measurements on plants. Therefore, I decided to come to the University of Tasmania to take an honors research degree in Bruce’s lab.

Who influenced your scientific thinking early in your career?
Just at the beginning of my PhD, several studies were published on auxins and their transport in plants, in particular work by Winslow Briggs on the movement of the growth hormone auxin across the tip of an Avena coleoptile. When light is shone onto it, the auxin moves away from the illuminated side toward the darker side, so the darker side grows more. When I saw the work described, I said to myself, “I want to make measurements of the electrical potential across the coleoptile,” and that was the main feature of my PhD.

I started working on developing a system for measuring electric current in Avena coleoptile using the systems laid out by Leicester McAulay, the founder of the biophysics lab at the University of Tasmania, and his predecessor, my then-supervisor Bruce Scott. My first two publications were about this work, first to show that there was an electrical wave that moved down the coleoptile when the light was shone on it, and then with some radioactive indolyl-3-acetic acid applied to the top to show that the auxin moving down could be traced and was linked to the electric wave. These two papers were letters to Nature, published in 1959 and 1965. With knowledge of my work, Winslow Briggs invited me for a postdoc, and we worked on phytochromes and phytochrome transformation with some electrical change.

Leicester had a key focus on the ability to design and conduct a well-planned experiment with good statistical fidelity, so that it is reproducible, and with well-defined conditions, so that observations are fully communicated and genuinely repeatable. Leicester, Bruce, and others in the biophysics group followed these approaches, which was unique at the time because previously methodologies had been poorly done. These clear methodological approaches were also used by PhD students in our lab, including me.

What scientific discoveries over the past couple of years and decades have influenced your research directions?
After an early observation of plant cell membrane potential, I wanted to find out more. In the 1950s and 1960s, there was still some discussion of whether the outer boundary of a plant cell should be called a membrane or a cell wall. Research led to discovery of the nature of the lipid bilayer membrane and its distinction from the cell wall with the complex microfibril and other structures. The cell wall is required to withstand turgor pressure, whereas the cell membrane controls the turgor itself in terms of water and nutrient exchange.

The discovery of semiconductor junctions happened while I was at school. The development of diodes, transistors, and integrated circuits allowed me to develop the equipment I wanted, and the gene revolution allowed us to start explaining the electrical observations we had made earlier, which had yet to be worked out.

If you were able to repeat your years as a graduate student or postgrad, would you do anything differently?
In terms of technical things, I don’t think there is anything special that I would have done differently. However, in looking back, one important thing I should have done differently was to start going to conferences earlier. In those days, around the 1960s, I thought conferences were attended by existing research scientists, not by students, even PhD students. That was a mistake; it’s possible that that perception was part of a mistake by the scientific societies and conferences themselves. Of course, ASPB does not make that mistake. So at present graduate students in America, Australia, and other countries are encouraged to go to conferences.

Because the MIFE system has become commercially viable and has turned some profit, we have real income from it—not a huge amount, but as an inventor, I get a royalty. I decided to donate the royalty to a university foundation fund that supports students working with the MIFE technique to attend conferences in Australia and overseas. Attendance at conferences is a crucial thing, and I think current graduate students should start doing this early.

As an employer, what are the key qualities you look for in a potential team member?
I have not been out in the big world as an employer, but I have employed graduate students whom I have supervised for their PhD. The very first quality, I suppose, is curiosity: Are you asking questions? Almost automatically, are you asking questions, about yourself even, little or otherwise? What is going on? Why is this happening? I would like to find more about this! The kind of curiosity that you see in a baby fooling around on the floor—I have seen that in my children, and you have seen young children, too. They want to find out what’s going on in this wonderful world we are in—that kind of curiosity. I look for genuine curiosity in prospective employees—those who want to know what is going on, those who have done some research.

In science, I look for personal integrity and integrity in science, respect for the observation in concert with the raw data, vigilance for unexpected results, and humility in the results. Of course, they should have some relevant training and qualifications, as well.

What do you think are good career moves for young scientists?
While choosing a career in plant science, have clear reasons why you want to join a particular company or group. Disregard the company you do not know completely, and look at the opportunities from the point of view of your background to make decisions on what to join or what suits you best.

What advice would you give to a student interested in plant biology today?
You need to have a broad overview of and basic background in science, including mathematics, physics, biology, and chemistry, among other subjects. These different subjects are especially necessary in plant science because for sound, good-quality research, you need well-defined research conditions, plenty of repeated observations under controlled conditions, competent statistical analysis, and reproducibility. Therefore, I advise young graduate students to consider issues of quality as they get involved in research.

What advice would you give educators to encourage young people to explore science and plant biology?
Try to stimulate the excitement. I got interested in plant science because my father took me on excursions with his students to the bush and the seashore. He would take time to talk about the interesting things that were happening there—for example, the marine algae and what they were doing there, as well as other important processes that were going on. When I got back from a conference in the 1980s, when the gene revolution was just beginning, there were these interesting discussions by people trying to transform plants. I spoke about that work on gene transformation to my students—that is an example of giving new and important information to stimulate interest.

Congressional Updates

Proposals to Bolster Competitiveness Through NSF
Federal policy makers in the House, Senate, and Biden administration are proposing separate approaches to improving U.S. scientific competitiveness, but the approaches all revolve around support for the National Science Foundation (NSF). The National Science Foundation for the Future Act, introduced in the House earlier this year, would authorize increased funding for NSF research, support STEM education at all levels, increase opportunities for broadening participation, and create a new Directorate for Science and Engineering Solutions to address societal grand challenges, including climate change and other environmental topics.

The House bill contains several provisions relevant to ASPB’s interests, including additional support for climate change research; research at the intersection of food, energy, and water; and reaffirmation of NSF’s role in sustaining biological collections. In the Senate, the Endless Frontier Act (EFA) was introduced by Majority Leader Chuck Schumer (D-NY) and Todd Young (R-IN). The EFA proposes the creation of a new Translational and Innovation Directorate authorized at a level of $100 billion (the House bill proposes a similar, but smaller new directorate). This directorate would have 11 technology focus areas, including one for biotechnology, medical technology, genomics, and synthetic biology. The bill was brought to the floor for consideration under a new title, the U.S. Innovation and Competition Act, and, after several days of debate and over 500 amendments, at the time of this writing, the bill looks poised to pass the Senate. Both the House and Senate bills only authorize funding levels; appropriated funding would come from different congressional committees.

In addition, the Biden administration included $50 billion for NSF in the recently released American Jobs Plan for supporting use-inspired research and improving U.S. scientific competitiveness. Both bills and the White House’s proposed plan show a burgeoning interest in significantly boosting scientific funding, especially for translational research. It is unclear how the different plans will come together, but it is clear that there is support for increased NSF funding, the STEM workforce and education pipeline, and outcomes-focused research. Finally, the preview of the president’s fiscal year (FY) 2022 budget request, with full details released on May 28, 2021, included $10.2 billion for NSF overall, and also proposed a new Directorate for Technology, Innovation, and Partnership.

Biden Administration Releases American Jobs Plan
On March 31, President Biden announced a signature legislative proposal focused on accelerating economic growth through an ambitious $2.25 trillion stimulus plan. The American Jobs Plan would modernize America’s infrastructure, spur climate action, strengthen the workforce and education, and promote U.S. global competitiveness. If passed by Congress, these goals would be achieved through investments in scientific research, federal incentives and mandates, encouragement of private sector participation and public–private partnerships, and policies that address broad and longstanding inequalities facing marginalized and underserved populations. Highlights include the following:

  • $50 billion is included for NSF, part of it for creating a new technology directorate.
  • $35 billion would be invested across the federal government to support climate technology R&D and mitigation techniques and practices. The proposal does not provide a detailed breakdown by federal agency but does highlight the creation of a new Advanced Research Projects Agency for Climate (ARPA-C) to fund high-risk, high-reward projects to reduce emissions, build resilience, and support climate research across the board. In addition, $5 billion is included to support and expand existing climate research programs.
  • $40 billion is included for research infrastructure at research institutions and national laboratories, including research facilities and computing centers and networks. The proposal does not specify the distribution of funding across federal agencies, but it would include agencies such as NSF and DOE.
  • The proposal mentions that investing in technological developments, including advanced carbon dioxide reduction methods like advanced pavements and other future-proof technologies, can help mitigate and redress the impacts of environmental disparities.
  • The proposal also calls for supporting rural communities by providing R&D funding to land grant universities and helping push the agriculture industry toward net-zero emissions.

Congress will now work to translate the American Jobs Plan into legislation. The likelihood of passage, either in whole or in part, remains uncertain.

House Science Committee Hearing on Rebuilding the Federal Workforce
The Subcommittee on Investigations and Oversight of the House Committee on Science, Space, and Technology held a hearing examining the challenges facing the federal scientific workforce. Subcommittee Chairman Bill Foster (D-IL) used his opening remarks to outline the inflection point facing the federal workforce and the broader R&D enterprise. He noted that the House and Senate have “dueling proposals” for substantially increasing investment in federal scientific research but pointed out that enabling such a ramp-up would require an accompanying strategy for reinvigorating the federal scientific workforce that oversees research programs and performs research at federal facilities. Ranking Member Jay Obernolte (R-CA), new to the subcommittee, emphasized the importance of empowering federal agencies to be entrepreneurial in their recruitment tactics.

Members of the subcommittee heard from the witnesses, which included current and former officials with the Government Accountability Office (GAO), Partnership for Public Service (PPS), Union of Concerned Scientists (UCS), and Environmental Protection Agency, about root causes of the scientific workforce recruitment and retention challenges. Witnesses cited negative public perceptions of working in government following political interference in science-based decision making, scarce opportunities for early career professionals, lengthy hiring processes, and failure to pursue more diversity in the workforce. These shortcomings, they argued, are leading causes of the federal government’s inability to compete with industry and academia in STEM talent recruitment.

Witnesses suggested solutions that varied widely, including public relations efforts and changes in compensation. In terms of specific employment mechanisms, Max Stier, president and CEO of PPS, called for more internship opportunities for early career professionals that could lead to full-time employment. Andrew Rosenberg, director of the Center for Science and Democracy at UCS, suggested that federal agencies be more aggressive in their outreach to minority serving institutions as a means to address a lack of diversity in the federal workforce. Candice Wright, acting director of Science, Technology Assessment, and Analytics at GAO, suggested that agencies offer increased pay to compete with industry’s ability to attract young talent with more lucrative salaries. Finally, there was unanimous agreement that agencies—except NASA—were not doing enough to tout their own missions and frame their open positions as opportunities to serve the American public.

Appropriations Committee Hearing on USDA’s Year Ahead
On April 14, Secretary of Agriculture Tom Vilsack appeared before the House Appropriations Committee’s Agriculture, Rural Development, and Food and Drug Administration Subcommittee to outline USDA’s plans for the upcoming year. During his opening remarks, he cited four pillars of focus for the agency: (1) prioritizing climate change and the unique opportunity it presents to bring jobs and resources back to the agricultural community, (2) addressing systemic discrimination across USDA programs, (3) increasing the profitability and resilience of agriculture in the United States, and (4) emphasizing nutrition insecurity in addition to food insecurity.

Vilsack drew attention to some ongoing and upcoming initiatives to address these overarching themes. He stated the intention to reestablish the task force on resilience and drought that was in place during the Obama administration and set up the Civilian Climate Corps. Ongoing initiatives include expanding climate hubs, working on flood mitigation practices, and filling the 100 positions at the National Institute of Food and Agriculture that remain vacant.

President’s FY2022 Discretionary Budget Proposal
On May 28, President Biden released his first budget request to Congress. Unrestrained by legally imposed budget caps for the first time in a decade, this proposal includes an 18% boost in discretionary spending, for a total of $1.522 trillion. A budget request was due to Congress the first week in February, but was significantly delayed by the transition from the Trump administration and the need to fill key federal leadership positions.

Although it is ultimately up to Congress to decide which proposals to embrace, modify, or reject as part of the annual appropriations process, Congress has been waiting on the new administration to highlight its major political priorities and new funding initiatives. President Biden’s top FY2022 budget priorities are public health, climate and clean energy, and education. Proposed FY2022 funding levels for major federal research and education agencies of interest are as follows:

  • $10.2 billion for NSF, a $1.7 billion or 20% increase over the FY2021 enacted level. Key elements include $9.4 billion to support fundamental research across NSF, an increase of $1.6 billion or 25%; establishment of a new Directorate for Technology, Innovation, and Partnership to strengthen U.S. leadership in emerging technology areas; $1.2 billion for climate and clean energy–related research, an increase of $500 million or 71%; $100 million for programs to increase participation in STEM fields, an increase of 50%; and support for construction of major NSF facilities and new smaller research facilities and equipment across the United States.
  • $46.1 billion for DOE, a $4.3 billion or 10% increase over the FY2021 enacted level, including $7.4 billion for the Office of Science, an increase of $400 million or 6%, with targeted investments in climate change modeling, new materials for clean energy technologies, and construction of user facilities at DOE national laboratories.
  • $51 billion for NIH, an increase of $8.1 billion. The funding increase would include $110 million, an increase of $100 million over the FY2021 enacted level, for NIH’s Climate Change and Human Health program to focus on issues related to the health impacts of climate change with a focus on health equity.
  • $27.8 billion for USDA, a $3.8 billion increase, including $4 billion for the Research, Education, and Economics mission area and a $40 million increase for USDA climate hubs to expand climate science tools and increase awareness and engagement in combating climate change.

Increasing Emphasis on Intersection Between Climate and Agriculture
The Biden administration has made clear that combating climate change will be a top priority for the duration of his term and that the agriculture sector will play a role in meeting those aspirations. The administration will take a “whole-of-government approach” to the climate crisis as exemplified by the January 27 Executive Order “Tackling the Climate Crisis at Home and Abroad,” which laid out a series of actions for climate change mitigation and resilience that agencies should take. The Executive Order specified several information collection activities, and USDA released a request for information to collect “input on a climate-smart agriculture and forestry strategy” that will inform some of the department’s steps to support the Executive Order and the administration’s goals.

Agriculture Secretary Tom Vilsack and Senior Climate and Agriculture Policy Advisor Robert Bonnie also plan to release a report on climate change in the spring that will outline the sector’s contributions to climate change and environmental quality and steps USDA will take over the next four years to address these issues. It is anticipated that carbon sequestration, regenerative agriculture, and soil health will be areas of interest, in addition to a continued focus on artificial intelligence and machine learning to improve resource use in farming.

In Congress, new leadership on both the House and Senate Agriculture Committees will focus on addressing climate impacts. Senate Agriculture Committee Chair Debbie Stabenow (D-MI) has said that climate change, supply chains, and the effects of COVID-19 on farmers will be top priorities. Similarly, House Agriculture Committee Chair David Scott (D-GA) will make climate change a major priority in addition to equity in agriculture and nutrition. Both the House and the Senate kicked off the 117th Congress with hearings focused on climate change, and hearings with leaders and stakeholders in the climate and agriculture space are expected to continue.

Farther on the horizon, conversations around the 2023 Farm Bill are beginning to take place. Although two years and an election will happen before then, congressional leaders are likely to push for the inclusion of climate provisions and will be open to new ideas for addressing climate change and agriculture.

Support, Even from Six Feet Apart: An ASPB SURFer’s Experience


Marty AlaniWhen I applied for a SURF fellowship in January of 2020, I thought the biggest challenge I would experience in the program would be having my experiments succeed. But in early March, it became clear that would not be the case. At my school, Cornell University, classes went entirely online, and undergraduates were denied access to research labs. As an added challenge to an already difficult year, I broke my leg at the end of the semester and lost much of my mobility. Despite the nationwide crisis, ASPB maintained the SURF program. Thanks to the support of my PI, Georg Jander, and ASPB, I was able to have a valuable research experience despite these setbacks.

In my SURF project, I investigated the transport and biosynthesis of cardiac glycosides in Erysimum cheiranthoides, a non–model plant in the Brassicaceae that synthesizes these compounds as an herbivore defense. Just before labs shut down on campus, I performed a mutagenesis experiment to screen for cardiac glycoside biosynthesis genes, and during the months I was kept from my research, my PI gave me regular updates on the mutant populations and maintained them for me, setting me up for success when I was allowed back into lab.

Gordon Younkin, a grad student in the lab, trained me in the basics of mass spectrometry, crucial for screening the mutant populations for phenotypes of interest. Georg, Gordon, and other lab members continued to help me manage my plants when my injury prevented me from doing so myself, and their help throughout the summer was crucial for my SURF experience. Because of the pandemic, it was harder to have the same mentor–student relationship with my PI and other lab members, yet I was able to receive the support I needed, even from 6 feet apart.

Although I’d had about a year of lab experience before my SURF fellowship, the summer of 2020 was my first time proposing, designing, and performing experiments for my own project. The plant I work on is a non–model organism, meaning that I had to optimize most procedures myself. This process was time consuming and challenging, but it ultimately gave me ownership of my project and produced results. My SURF experience was very encouraging for me as a scientist and helped cement my plan to continue on to graduate school after graduation.

In the year before the fellowship, I found it difficult to complete work in the lab alongside my other responsibilities. Summer research allowed me to focus more completely on my work, become more acquainted with the literature, and complete time-intensive experiments that would be difficult during the semester. Since I began working in the Jander lab, I have become interested in plant secondary metabolism and how it mediates interactions with other organisms. I am excited to learn about current research in plant natural products at Plant Biology 2021 and to meet PIs to create contacts for graduate school.
