ASPB is pleased to announce the award winners for 2020.



The Charles F. Kettering Award was established by the Kettering Foundation to recognize excellence in the field of photosynthesis. 


The 2020 Charles F. Kettering Award recipient is Donald Bryant, who is the Ernest C. Pollard Professor of Biotechnology, Department of Biochemistry and Molecular Biology, at Pennsylvania State University. Don’s seminal contributions over a five-decade career include elucidation of the structure, function, and assembly of multiple types of photosynthetic complexes, including phycobilisomes, chlorosomes, and Photosytem I, as well as unraveling biosynthetic pathways for chlorophylls, bacteriochlorophylls, and carotenoids.  Most recently, he characterized the response of cyanobacteria to red light, demonstrating that they extensively remodel their photosynthetic apparatus by synthesizing new chlorophylls, phycobiliproteins, and photosystems to adapt to the changes in the incident light spectrum. Introduction of this capability into crop plants could increase plant productivity by expanding the wavelengths of light utilization.



The Charles Reid Barnes Life Membership Award is the society’s oldest award established in 1925 at the first annual meeting of the Society through the generosity of Dr. Charles A. Shull. It honors Dr. Charles Reid Barnes, the first professor of plant physiology at the University of Chicago. It is an annual award for meritorious work in plant biology. Membership is a requirement for the award and the award provides a life membership in the Society to an individual who is at least sixty years old. 


In 2020, ASPB honors two outstanding recipients, Don Ort and Brian Larkins for the Charles Reid Barnes Life Membership Award.

Don Ort is the Robert Emerson Professor of Plant Biology and Crop Sciences at the University of Illinois. Don’s research on photosynthesis and plant-environment interactions spans scales from the molecular level to the biochemical, physiological, agronomic scales and final at the ecological scale. His research leverages fundamental insights into mechanisms to advance improvements in crop performance and addresses climate change’s intersection with crop productivity. Throughout his career, Don has generously served the plant science community in many capacities, including as President of ASPB and as Editor-in-Chief of Plant Physiology and the mentoring of a generation of students and post-doctoral scholars.

The second awardee for the Charles Reid Barnes Life Membership Award is Brian Larkins, associate vice chancellor emeriti for life sciences and professor emeriti, University of Nebraska-Lincoln. Brian is one of the world’s foremost experts in maize seed development and protein assembly processes and he created an extensive body of work impacting agriculture. Brian has also generously dedicated his time and energies in service of ASPB. He served as Editor-in-Chief of The Plant Cell, ASPB President, President of the International Society for Plant Molecular Biology, is a founding member of the ASPB Legacy Society working tirelessly to ensure a solid financial future for ASPB. Throughout his distinguished career, Brian has served on numerous evaluation committees, review teams, and advisory boards in support of the plant science community. Brian mentored a generation of graduate students, postdocs, and junior faculty, providing advice on career decisions and emerging opportunities. Above all, he shows a benevolence to his friends and colleagues that is uncommon amidst the pressure and competition of scientific endeavor.



The Lawrence Bogorad Award for Excellence in Plant Biology Research was initiated 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. This award is made to a plant scientist whose work both illuminates the present and suggests paths to enlighten the future.


The 2020 Lawrence Bogorad Award for Excellence in Plant Biology Research awardee is Alice Cheung, who is Professor in the Department of Biochemistry and Molecular Biology at the University of Massachusetts Amherst and is internationally recognized for her discoveries on the signaling systems that control pollination and fertilization. Alice invented a widely used assay termed the “semi-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 ROS production in both root hairs and in male-female pistil interactions. Her efforts revealed that FERONIA is a multi-functional regulator, stimulating many laboratories to study its role in diverse systems.


The Stephen Hales Prize honors the Reverend Stephen Hales for his pioneering work in plant biology published in his 1727 book Vegetable Staticks. It is an award for a ASPB scientist who has served the science of plant biology in some noteworthy manner.


The 2020 Stephen Hales Prize awardee is Julian Schroeder. Julian is the Novartis Chair and Distinguished Professor of Biology in the Division of Biological Sciences at the University of California San Diego and was founding Co-Director of the Center for Food and Fuel for the 21st Century at UCSD. Julian has made successive fundamental discoveries in plant biology and mentored generations of younger scientists, many of whom are themselves now leaders in their fields. Julian is a leader in plant electrophysiology and was one of the pioneers of patch clamping in plants, allowing detailed characterization of the function and regulation of ion channels in plant cells, which revolutionized the understanding of the processes by which stomata open and close. His work has provided major insights into the signaling pathways by which abscisic acid and carbon dioxide close stomata, the role of calcium signals in stomatal signaling, and the molecular bases for mineral uptake and metal toxicity.



The Charles Albert Shull Award award was initiated in 1971 to honor Dr. Charles A. Shull’s founding of and early support for ASPB. This award honors an individual 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.


The 2020 recipient of the Charles Albert Shull Award is  Zachary B. Lippman. Zachary is the Jacob-Goldfield Professor of Genetics at Cold Spring Harbor Laboratory and an Investigator of the Howard Hughes Medical Institute. Zach has made pioneering contributions to our understanding of the genetic and regulatory networks and mechanisms that control floral meristem activity in tomato and related plants in the Solanaceae, using a combination of classical and quantitative genetics, genomics, and cutting-edge gene editing. Moreover, he has demonstrated an exceptional ability to translate his fundamental discoveries in plant biology into novel germplasm resources and innovative strategies for agricultural crop improvement.
