[Co-phylogeny of Perkinsus-Crassostrea] - RADseq SNP genotypes of Perkinsus marinus and Crassostrea virginica from the Gulf of Mexico and eastern Atlantic shorelines collected from 2011-2019 (The genetic legacy of an Asian oyster introduction and its disease-causing parasite)

The eastern oyster, Crassostrea virginica, is among the most important aquacultured species in the United States. Natural and farmed oyster populations can be heavily impacted by ‘dermo' disease caused by an alveolate protist, Perkinsus marinus.

Here, we used restricted site-associated DNA sequencing (RADseq) to simultaneously examine the spatial population genetic structure of host and parasite. We analyzed 393 single-nucleotide polymorphisms (SNPs) for P. marinus and 52,100 SNPs for C. virginica from 36 individual oysters from the Gulf of Mexico (GOM) and mid-Atlantic coastline. This dataset includes metadata, methods, links to published code and processed data used to generate figures for results publication Weatherup et al. (2024, doi:10.1017/S0031182024000611) titled "Co-phylogeographic structure in a disease-causing parasite and its oyster host." This dataset also includes genetic accession identifiers for sequence data contributed to the National Center for Biotechnology Information (NCBI)'s Sequence Read Archive (SRA), available under BioProject PRJNA1074361.
