Polyploidy: Genetics, Evolution and Ecology.
Studies of the genetic, evolutionary, and ecological consequences of polyploidy represent an active and important research area within plant biology. As most plants have at least one genome duplication event in their evolutionary history, the impacts of polyploidy on plant diversification are pervasive, and important to our overall understanding of patterns and processes of diversification in plants. Recent progress in our understanding of the impacts of polyploidy comes from a diversity of approaches and taxa, as illustrated by the talks in this symposium. Talks will include consideration of gene dosage effects, changes in gene expression, and the identification of physiological changes in polyploids and their molecular characterization. Talks also will include studies of the ecology and geographic distribution of both sexual and apomictic polyploids, and evidence of adaptive phenotypic changes in natural allopolyploid populations that do not result directly from genome duplication. Taxa will include a variety of angiosperms and ferns, formed on a range of time scales from neopolyploids to paleopolyploids. Together these talks illustrate progress in linking ecological, phenotypic, and physiological variation with gene expression and molecular mechanisms to further our understanding of the role of polyploidy in plant evolution.
