Comparative metabolomics in hybridizing milkweed species: adaptation and hybrid dysregulation
Carrie Olson-Manning, Associate Professor of Biology at Augustana University
Abstract
Despite the remarkable chemical diversity generated by plants, our understanding of both metabolite diversity and the associated effects on plant survival and fitness remains limited to a set of well-studied pathways. This seminar will discuss metabolic divergence between two closely-related milkweed species, Asclepias speciosa and Asclepias syriaca, inhabiting western and eastern North America, respectively. With untargeted metabolomics, we identified divergence in stress-response and signaling pathways between the species, environment-specific expression of candidate pathways, and the disruption of those pathways in hybrids. The differences in stress-metabolism provide a unique avenue to study postzygotic isolation mechanisms and species-specific responses to environmental challenges.
Join us on Monday, April 15 at 1:30 PM in Stephens Room (3503 Thomas Hall) and ZOOM for the Genetics and Genomics Seminar Series.
