Comparative transcriptome analysis of the differentiating gonads in Scatophagus argus

The reproductive-related studies, including genetic and genomic such as gonadal transcriptome analyses, have previously focused on the adult spotted scat, with little information juvenile fish. Transcriptomics is a powerful tool that allows for massive parallel analysis to identify differential expression patterns of gene holistically at particular stage in cell or tissue development. This study presents first report differentiating (juvenile; 4 months after hatch; I ovary testis) scat gonads. revealed potential reproduction development-related genes. A total 25936 genes were identified, which 16248 co-expressed, 17893 17258 expressed males females, respectively, from sequence data testis (n = 3) 2). 6549 differentially (DEGs) identified between females. Genes attributable male gonad development pathway dmrt1 , gsdf amh are significantly testes, while female-related foxl2, cyp19a1a, 42sp50 sox3 considerably ovaries. In addition, dmrt1/dmrt1y was not female (FPKM=0.00), its paralog dmrt1b both pathway, dmrt1y critical sex determination maintenance foxl2/foxl3 cyp19a1a pathway. current studies provide an insight into gonadal-related gonads scat.
