- Abstract
In this study, the cDNA of dmrt1 gene from the Chinese sturgeon Acipenser sinensis was isolated and its expression pattern was characterized in different tissues of immature A. sinensis. By real-time quantitative PCR (qrtPCR) analysis, the A. sinensis dmrt1 mRNA was detected mainly in gonad and with a higher level in the testis than the ovary, especially in 3 and 4 year-old samples. This indicated that the dmrt1 expression exhibited gradual testis specificity with development. The subcellular localization analysis indicated that the Dmrt1 protein exists only in germ cells and not in somatic cells. These results suggest that A. sinensis dmrt1 might be a highly specific sex differentiation gene for testis development and spermatogenesis., (© 2015 The Fisheries Society of the British Isles.)
