Project description:Boihai Red is new strains of inter-specific hybridizing the bay scallop (Argopecten irradians irradians) with the Peruvian scallop (Argopecten purpuratus). Orange color variant of adductor muscle have been developed through successive selective breeding in this strain. In the present study, transcriptomic was conducted on orange and white adductor muscle tissues. Transcriptomic analysis showeds 416 differentially expressed genes (DEGs) were identified between white and orange adductor muscle tissues in Boihai Red Scallop, with 216 up regulated and 200 down. In DEGs, apolipophorin, CYP450 and tyrosinase were expressed highly in orange adductor muscle tissues, which related to carotenoids or melanin. It is probable that not only carotenoids, but also melanin act on orange color of adductor muscle. This study provides valuable genetic resources for understanding underlying mechanisms and pathways of adductor muscle color.
Project description:Boihai Red is new strains of inter-specific hybridizing the bay scallop (Argopecten irradians irradians) with the Peruvian scallop (Argopecten purpuratus). Orange color variant of adductor muscle have been developed through successive selective breeding in this strain. In the present study,proteomic were conducted on orange and white adductor muscle tissues.Notably, 74 differentially expressed proteins (DEPs) were identified by lable free proteomics, including 36 up and 38 down regulated. In DEGs, apolipophorin, CYP450 and tyrosinase were expressed highly in orange adductor muscle tissues, which related to carotenoids or melanin. In DEPs, high expression of VPS and TIF in orange adductor muscle tissues indicated that proteins outside the carotenoid pathway might also affect carotenoid biosynthesis. In addition, RAB11A related to melanin was also expressed highly in orange adductor muscle tissues at protein level. It is probable that not only carotenoids, but also melanin act on orange color of adductor muscle. This study provides valuable genetic resources for understanding underlying mechanisms and pathways of adductor muscle color.
Project description: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
