To investigate the biological response mechanisms of the Yesso scallop(Mizuhopecten yessoensis)under static hydraulic pressure stress,the transcriptomes of the adductor muscle,gills,and mantle were analyzed in the Yesso scallops with shell length of(75.64 mm±2.15 mm)in a FH-100M manual hydrostatic press with a volume of 2 L at a high pressure of 25 MPa(equivalent to 2 500 m water depth)by transcriptome sequencing technology.The results showed that 130 upregulated genes and 150 downregulated genes were identified in the adductor muscle,314 upregulated genes and 390 downregulated genes in the gills,and 314 upregulated genes and 390 downregulated genes in the mantle by transcriptome screening.GO enrichment analysis revealed that the annotated differentially expressed genes were found to be primarily associated with activities related to cysteine-type endopeptidase and in-hibitor activities involved in apoptosis,organellar membranes,and innate immune response.KEGG pathway analy-sis showed that the differentially expressed genes were involved in antigen processing and presentation,apoptosis,endoplasmic reticulum protein processing,and the MAPK signaling pathway.It was found that the differentially ex-pressed genes in the Yesso scallop exposed to static hydraulic pressure stress were primarily enriched in pathways related to signal transduction and immunity.The findings provide valuable data and references for subsequent re-search.
