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.
