Genome-wide identification and expression analysis of Dmrt gene family and their role in gonad development of Pacific oyster (Crassostrea gigas)

In this study, a total of three members of the Dmrt gene family were identified and characterized in Crassostrea gigas, and all these CgDmrt genes contained a conserved DM domain. Analysis of the phylogenetic tree and gene structure revealed that Dmrt genes clustered on one branch may have similar functions in bivalves. Expression profiling of CgDmrt mRNA in different tissues and stages of gonad development indicated that CgDmrt3 exhibited sexually dimorphic expression and played an important role in the development of the male gonad in C. gigas. Furthermore, analysis of CgDmrt mRNA expression between fertile triploids and sterile triploids showed that CgDmrt3 may be involved in sperm production. Collectively, the systematic analysis of the CgDmrt genes will provide potential insights into the function of these genes in gonadal development.PMID:37751789 | DOI:10.1016/j.cbpb.2023.110904
