Gene Expression Divergence Between Locally Adapted Inland Annual and Coastal Perennial Ecotypes of Mimulus guttatus Across Developmental Stages.

ABSTRACT: The action of natural selection across heterogeneous natural landscapes drives local adaptation and the formation of plant ecotypes, the precursors to new species. Plant ecotypes typically differ significantly in morphology, physiology, and development, yet our understanding of their underlying genetic basis remains limited. Despite their importance, studies of the molecular underpinnings of ecotypic divergence through developmental stages are rare. Here, we compared gene expression at different developmental time points between ecologically reproductively isolated coastal perennial and inland annual ecotypes of the yellow monkeyflower, Mimulus guttatus. We took two major approaches to understand differences in gene regulation between the ecotypes at the level of gene networks. First, we e
