effects of water temperature stress in the adductor muscle of Argopecten irradians concentricus by transcriptomics

Both high and low water temperature stresses are major environmental threats of growth and productivity in aquatic animals. However, the mechanism of response to temperature stress of scallop remains unclear. In this study, Argopecten irradians concentricus treated with high and cold temperature stress were analysed with the transcriptomes, metabolomes and integrated network analysis. Transcriptomic analyses revealed that there were many differentially expressed genes enriched calcium ion, kinase activity, phosphatase activity, and lipid related pathways between high temperature stress group and the control group. Although similar results were found in the low temperature stress group versus the control group, the genes enriched in these pathways were different. Moreover, much more genes were enriched in transcription factor activity in the low temperature stress group versus the control group Overall design: Total mRNA profiles of the control group under normal temperature,high temperature and cold temperature were generated by deep sequencing, in triplicate.
