The Charles Albert Shull Award

This award was initiated in 1971 by the Society to honor Dr. Charles A. Shull, whose personal interest and support were largely responsible for the founding and early growth of the Society. It is a monetary award made annually for outstanding investigations in the field of plant biology by a member who is generally under forty-five years of age on January 1st of the year of presentation, or is fewer than ten years from the granting of the doctoral degree. Breaks in careers will be considered when addressing the age limit of this award. The recipient is invited to address the Society at the annual meeting the following year.

Jiří Friml

2016 Winner: Jiří Friml

Jiří Friml (professor, Institute of Science and Technology Austria) is the 2016 recipient of the Charles Albert Shull Award. Jiří has played a leading role in elucidating the biology of polar auxin transport, including the discoveries that PIN family proteins mediate auxin efflux from the cell and that the PIN proteins are expressed at cell poles where they establish a tissue-wide polar auxin gradient responsible for the apical–basal axis of the plant embryo and organs. Jiří showed that this mechanism accounts for developmental plasticity via which growth and development reorient in response to developmental or environmental cues. Jiří discovered that clathrin-mediated endocytosis plus polar recycling give rise to the polar distribution of PIN proteins. He found that some PIN family members reside in the endoplasmic reticulum, where they regulate cellular levels of auxin. His work has had major impacts on several areas of plant biology, including hormone signaling (auxin transport), plant development (cell polarity and auxin gradients), and plant cell biology (endocytosis).
