Gene expression differentiation is consistent with local adaptation across an elevational gradient in Drummond's rockcress (Boechera stricta).

Abstract excerpt

A central goal of evolutionary biology is to understand the mechanisms conferring adaptation. Gene expression is sensitive to environmental variability; thus, investigating gene expression differentiation among populations may reveal signatures of selection from predictable environmental conditions. Environmental pressures which covary with elevation gain (e.g. temperature) result in stark environmental...
