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

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.
