Molecular Ecology Tisinai, Shelby [1], Busch, Jeremiah [2]. Gene expression plasticity in response to an environmental gradient in a mountain crucifer. Plasticity is thought to facilitate the adaptation of populations to novel environments. Gene expression is a highly variable component of phenotypic plasticity with important fitness consequences, but gene expression analyses to quantify plasticity in wild relatives of model species is under-utilized. Because of the central role gene expression plays in plasticity, there is a need to evaluate it in whole transcriptomes to understand its potential adaptive value. The objective of the proposed work is to determine how adaption to elevation has influenced selection on plastic response. Using Cardamine cordifolia, a wetland crucifer endemic to western USA mountain ranges and a wild relative of Arabidopsis thaliana, we plan to test the following hypotheses: (1) adaptation to elevation-specific conditions leaves a genetic signature; (2) historic environmental conditions specific to elevation explain differentiation in plasticity between low and high elevation populations; (3) genes contributing to adaptation can be predicted on the basis of their function and regulation. Together, these aims will shed light on the mechanisms plants utilize to adapt to environmental change.
