ATAC-Seq and RNA-Seq data of Crassostrea ariakensis at different gonadal developmental stages

Jinjiang oyster Crassostrea ariakensis is an economically and ecologically important species in China. In this study, RNA sequencing (RNA-seq) and assay for transposase-accessible chromatin using sequencing (ATAC-seq) were performed respectively to explore the gene expression and dynamic changes of chromatin accessibility among the oysters with different glycogen contents. This study will enrich basic research data and provide insights into the molecular mechanisms underlying the regulation of glycogen metabolism in oyster.
