To investigate the differences between mantle repair tissue and normal mantle tissue of Panopea japonica following shell damage, this study employed RNA-Seq and bioinformatics analysis to compare the transcriptomes of mantle repair tissue (A4Y1), external mantle tissue (A4Wa1), and internal mantle tissue (A4Wb1). A total of 1864 differentially expressed genes (DEGs) were identified across the three types of mantle tissues (selection criteria: p.adj < 0.05 and |log2FoldChange| ≥ 1). Among these, 807 upregulated and 598 downregulated genes were found in A4Wa1 vs. A4Y1, 678 upregulated and 563 downregulated genes in A4Wb1 vs. A4Y1, and 44 upregulated and 142 downregulated genes in A4Wa1 vs. A4Wb1. GO and KEGG enrichment analyses revealed significant enrichment of these DEGs in pathways associated with biomineralization and immunity, with higher expression levels in repair tissues. These findings indicate that the three mantle tissue types exhibit significant differences in biomineralization and immune functions, which are likely linked to the shell repair mechanisms of P. japonica. This study provides data support for further exploration of mantle functions in P. japonica and serves as a reference for research on mantles in other mollusks. %K 日本海神蛤， %K 外套膜， %K RNA-Seq， %K 生物矿化
