Fig. 4From: Analyzing the gonadal transcriptome of the frog Hoplobatrachus rugulosus to identify genes involved in sex developmentqRT-PCR analysis of 17 differentially expressed genes (DEGs) in male/female gonads from Hoplobatrachus rugulosus at two ages. Gapdh expression was detected as a reference gene to normalize the qRT-PCR data. Data are expressed as the mean + standard error. *P < 0.05; **P < 0.01; ***P < 0.001Back to article page
