Few empirical systems allow to jointly examine the evolutionary patterns and genetic mechanisms resulting in the emergence of complex phenotypes. The repeated evolution of wind pollination from insect pollination, dioecy (separate sexes) from hermaphroditism and polyploidy (multiple genomes within a species) from diploidy in a group of closely related species provides a unique opportunity for multiple, independent comparisons of trait evolution. The overall goal of this project is to investigate patterns of correlated trait evolution in a phylogenetic comparative framework, to inform future directions on the underlying genetic basis of complex phenotypes (wind pollination syndrome, separate sexes) that have evolved repeatedly in a diverse angiosperm lineage. This research thrust on the flowering plant genus Thalictrum (Ranunculaceae) focuses on the evolutionary consequences of the emergence of novel floral traits and is funded by an NSF-OPUS mid-career synthesis award.
