Title: An evolutionary genomics approach to the evolution of plasticity.
Abstract:
All traits are expressed in a specific environment, so understanding the evolution of environmental responses (aka plasticity) is crucial for determining evolutionary forces shaping genetic variation for traits. In this talk I'll discuss a few ways my lab has approached this topic using evolutionary genomics in plants. First, I'll present an investigation into whether gene expression plasticity to herbicides in weedy Morning Glories tends to be beneficial or deleterious. Second, I'll show work on how the accumulation of deleterious mutations could limit the evolution of expression plasticity.
