This week, we welcome Wendy Van Drunen.
The immediate phenotypic effects of whole-genome duplication on asexual reproduction through clonality
Abstract: Polyploidy, having 2 or more complete chromosome sets, is extremely common throughout the flowering plants and is believed to play a large role in speciation and diversification. However, surprisingly little is known about the mechanisms that contribute to polyploid success in natural populations. Here I will present my work on the immediate phenotypic effects of whole-genome duplication (WGD) on asexual reproduction via clonality, a trait that is expected to promote polyploid establishment, by comparing diploids and newly synthesized polyploids in two study species. The use of synthesized polyploids in studying the evolutionary and ecological consequences of polyploidy remains rare, but is indispensable for understanding the specific role of WGD in evolutionary divergence between polyploids and their diploid progenitors.
