The Assembly, Resequencing, and Population Genomics of the Eastern Oyster Genome

The eastern oyster, Crassostrea virginica, is a valuable fishery and aquaculture species that provides critical services as an ecosystem engineer. Oysters have a life-history that promotes high genetic diversity and gene flow while also occupying a wide range of habitats in variable coastal environments from the southern Gulf of Mexico to the southern waters of Atlantic Canada. To understand the interplay of genetic diversity, gene flow, and intense environmental selection, we used whole genome re-sequencing data from 90 individuals across the eastern United States and Gulf of Mexico, plus 5 selectively bred lines.

东部牡蛎（Crassostrea virginica）是兼具重要渔业与水产养殖价值的物种，同时作为生态系统工程师提供关键的生态系统服务。牡蛎的生活史特征可促进高遗传多样性与基因流，同时其栖息范围覆盖从墨西哥湾南部到大西洋加拿大南部海域的各类多变近岸生境。为解析遗传多样性、基因流与强烈环境选择之间的相互作用，本研究使用了美国东部及墨西哥湾沿岸90个个体的全基因组重测序数据，外加5个选育品系的相关数据。
