Sex determination and sex differentiation are important phenomena in fish, but the mechanisms of sex determination in Takifugu rubripes are poorly understood. In our study, the expression patterns of genes for DMRTs (DMRT1, DMRT2 and DMRT3),sox9a and sox9b in T. rubripes tissues were verified with the Reverse Transcription (RT)-PCR detection. It is showed that DMRT1 expressions in testis and ovaries were much lower, and no expressions were fotmd in muscle, blood and tailfin. However, expressions for DMRT2 and DMRT3 were not found in the tissues stated above. Transcripts of sox9a were detected in muscle, fin, ovary and testis, but not in blood, whereas sox9b expression was only detected in ovary. The expression patterns of DMRTs, sox9a and sox9b in T. rubripes gonads suggest that these genes may not be sex-specific.
