Integrated RNA-seq and RNAi Analysis of the Roles of the Hsp70 and SP Genes in Red-Shell Meretrix meretrix Tolerance to the Pathogen Vibrio parahaemolyticus.

ABSTRACT: The "Wanlihong" Meretrix meretrix (WLH-M) clam is a new variety of this species that has a red shell and stronger Vibrio tolerance than ordinary M. meretrix (ORI-M). To investigate the molecular mechanisms responsible for the WLH-M strain's tolerance to Vibrio, we challenged clams with Vibrio parahaemolyticus and then assessed physiological indexes and conducted transcriptome analysis and RNA interference experiments. The mortality, tissue bacterial load, and hemocyte reactive oxygen species level of ORI-M were significantly higher than those of WLH-M, whereas the content and activity of lysozyme were significantly lower. Gene Ontology functional annotation analysis and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis revealed that immune and metabolic pathways were enri
