Lack of GxE suggests limited potential for evolutionary changes in plasticity in the eastern oyster, Crassostrea virginica

We assess the physiological and transcriptomics response of C. virginica, eastern oysters, raised in common garden at two Louisiana, USA estuaries naturally differing in salinity regimes. We use a combination of growth rates, P. marinus infection levels, and 3 prime RNA sequencing (TagSeq) to identify the effect of genotype, environment, and genotype by environment interaction on the oyster's response to site.
