Lawrence Bogorad Award for Excellence in Plant Biology Research

The ASPB Lawrence Bogorad Award for Excellence in Plant Biology Research was approved by the Society’s executive committee in 2005 to honor Dr. Bogorad’s many contributions to plant biology, including his influential efforts to bring the techniques of molecular biology to bear on problems in plant biology; his groundbreaking research on chloroplast genetics, biogenesis, structure, and function;and his inspired teaching and mentoring. The ASPB Lawrence Bogorad Award for Excellence in Plant Biology Research is a monetary award made biennially to a plant scientist whose work both illuminates the present and suggests paths to enlighten the future.

2020 Winner: Alice Cheung

Alice Cheung is recognized for her many contributions to the understanding of the signaling systems that control pollination and fertilization. Alice biochemically characterized transmitting tract-specific proteins and demonstrated that they act on pollen tubes. She invented a widely used assay, the semi–in vivo pollen tube growth assay, that has had a major impact on the field. Using elegant imaging techniques, Alice defined components of the pollen tube endomembrane system and trafficking by the actin cytoskeleton. Alice identified Rab GTPases that regulate polarized tip growth. She determined that a receptor-like kinase, FERONIA, plays key roles in signaling through reactive oxygen species production in both root hairs and male–female pistil interactions. Her efforts revealed that FERONIA is a multifunctional regulator, stimulating many laboratories to study its role in diverse systems. Her most recent work solves the mystery of how multiple pollen tubes are prevented from entering an ovule when one tube has already entered.
