From Genes to Distributions: physiological ecology as an integrator of polyploid biology.

Polyploidy is widely considered to be an important driver of plant evolution by facilitating diversification and speciation. Studies have shown that polyploidization can induce extreme genetic and genomic changes, which have been postulated to increase the potential for physiological trait innovations required for polyploid establishment. In addition, classic and recent ecological studies have shown that polyploid species can evolve unique and sometimes extreme climatic distributions relative to their progenitors, which implies distinct physiologies between polyploids and progenitors. Recent studies on the physiological ecology of polyploids have provided new insight to the mechanisms underlying the ecological and evolutionary success of polyploid plants. We are now seeing physiological studies inform polyploid biology like never before. This symposium will draw on research from multiple disciplines and scales of inquiry (from genes to distributions), with a central focus on physiology. The invited speakers will present the latest work on the physiological impacts of polyploidy, including cutting-edge research that links physiology with genetics, ecology, and evolution. This symposium will present a balanced view of polyploidy across vascular plants, and will include current research on polyploidy in ferns, gymnosperms, and angiosperms. In this way, we will bring attention to the ecological and evolutionary significance of polyploidy across all major vascular plant lineages, cross multiple sections of BSA including Genetics, Systematics, Ecology, Physiology, and Pteridological, and draw interest from other societies such as ASPT and AFS.
