Crassostrea virginica isolate:SEPT_11B Genome sequencing
We present a new chromosome-level assembly for the eastern oyster (Crassostrea virginica), constructed using PacBio HiFi long reads, Illumina whole-genome sequencing, and Hi-C scaffolding. This updated reference genome is intended to support functional, comparative, and population genomic studies in C. virginica and related molluscan species. The improved assembly will enable detailed investigations of genome structure, regulatory evolution, and gene family diversification across oysters. It also provides a valuable resource for research into adaptation, resilience, and disease resistance in this ecologically and economically important marine organism.
