Abstract
Evolutionary theory predicts that transitions in ploidy and mating system should have major genome-wide effects on the nature and efficacy of natural selection. While over long evolutionary timescales there is clear evidence that loss of recombination and transitions in ploidy have important effects on the genome, the processes driving these shifts remain unclear. Plants routinely undergo major transitions in ploidy and mating system, providing an outstanding opportunity to examine the evolutionary processes occurring at the earliest stages of these transitions. I will discuss work in the lab examining how rapidly plant evolutionary transitions influence genome-wide selection, and our ongoing attempts to understand the unique and joint effects of ploidy and recombination in driving genome-wide selective pressures.
