Population epigenetic divergence exceeds genetic divergence in the Eastern oyster Crassostrea virginica in the Northern Gulf of Mexico

Abstract: Evolutionary Applications. 2020;13:945-959. | 945 wileyonlinelibrary.com/journal/eva AbstractPopulations may respond to environmental heterogeneity via evolutionary divergence or phenotypic plasticity. While evolutionary divergence occurs through DNA sequence differences among populations, plastic divergence among populations may be generated by changes in the epigenome. Here, we present the results of a genome-wide comparison of DNA methylation patterns and genetic structure among four populations of Eastern … Show more

“…Although DML were found across various genome features, they were mostly in exons and introns. This is consistent with a recent study of C. virginica gill tissue found differentially methylated regions in response to a salinity gradient were primarily in genic regions (Johnson and Kelly, 2019). Interestingly, DML were not found consistently in one particular region of a gene.…”

“…The association between DNA methylation and phenotypic differences in these corals demonstrates that epigenetic regulation of genes is potentially important for acclimatization and adaptation to environmental perturbation. Recent examination of C. virginica methylation patterns in response to a natural salinity gradient suggests that differential methylation may modulate environmental response in this species (Johnson and Kelly, 2019).…”

“…In the eastern oyster (C. virginica) DNA methylation is more divergent between populations than single nucleotide polymorphism-based estimates of divergence, suggesting a nongenetic (i.e., environmental) influence on DNA methylation (Johnson and Kelly, 2020). Together, these studies provide some evidence of an association between DNA methylation and transcriptomic expression levels; however, the functional consequences of changes in DNA methylation are still largely unknown in bivalves.…”

“…Presence of high molecular weight DNA was confirmed using a 1.5% agarose gel, and DNA concentration was verified using a Qubit 3.0 Fluorometric dsDNA BR assay kit (Q32850; Life Technologies). The epiGBS library preparation followed previously published methods (Van Gurp et al, 2016;Johnson and Kelly, 2020). Briefly, a total of 500 ng of purified genomic DNA was double digested using the two frequent cutter enzymes AseI and NsiI (NEB-R0127L and NEB-R0526L; Van Gurp 2016).…”
