16th GCOE International Seminar
Speaker: Erika Edwards (Brown University)
Date: June 12 (Wed) 17:00-18:00
Room: #3521 on 5th floor of Faculty of Sciences Building #3
Title: Convergent evolution in plants
Abstract: At first glance, plants are remarkably diverse, measured by any yardstick. A closer look, however, will reveal a very common set of ecological syndromes that have evolved time and time again, in many distantly related plant groups, suggesting that there are certain evolutionary trajectories in plants that are more 'accessible' than others. I will discuss the evolutionary history of two very distinct plant ecological syndromes: C4 photosynthesis, and the temperate deciduous leaf habit. In both cases, there is a strong phylogenetic clustering of origins, implying that certain lineages have an elevated evolutionary accessibility to these syndromes. In the case of C4 photosynthesis, we have identified a leaf anatomical trait in non-C4 relatives that may act as a precursor to the C4 syndrome. From our work on tropical-temperate transitions in the woody plant lineage Viburnum, we have identified a new suite of leaf traits that have co-evolved during movements into the northern temperate zone, and suggest a new hypothesis for why so many temperate trees have toothed or lobed leaves.

We are also planning to go dinner with Dr. Edwards and Dr. David Chatelet after the seminar. If you want to join us, please contact a GCOE staff. We are looking forward to your participation.
