Biography

Scott Poethig is a distinguished professor emeritus in the Department of Biology at the University of Pennsylvania. He specializes in plant developmental biology, focusing on critical processes such as the juvenile-to-adult transition in plants, known as vegetative phase change. This transition is marked by changes in shoot architecture, cellular differentiation, and physiological processes like photosynthesis. His research emphasizes the importance of plant-specific transcription factors and their regulation by microRNAs, particularly miR156 and miR157, in driving the vegetative phase change. Poethig has also explored the evolutionary significance of vegetative phase change in various plant species, including studies on Acacia species that maintain juvenile characteristics. In addition to his specific research interests, he has developed genetic tools for Arabidopsis thaliana, including transgenic lines that facilitate the monitoring of genetic analysis tasks. He has made significant contributions to our understanding of plant biology, genetics, and genomics, and has taught various courses at the university.
