SOX transcription factors play an irreplaceable role in biological developmental processes. Sox genes have been identified in a wide variety of species; however, their identification and functional analysis in the genome of the Chinese soft-shell turtle (Pelodiscus sinensis) have not been performed. In the present study, the Chinese soft-shell turtle genome was found to contain 17 Sox genes, which were categorized into seven groups according to their phylogenetic relationships. Gene structure and protein motif analysis of the Sox genes showed that within the same phylogenetic group, their exon-intron number and motif structure of the Sox family were relatively conserved, but diverged in the comparison between different groups. Sexual dimorphism expression analysis for the Sox genes displayed that Sox8 and Sox9 were upregulated in the testis, while Sox3, Sox7, Sox11, and Sox13 were upregulated in the ovary. A correlation network analysis of SOX transcription factors with their target genes analysis showed that Sox3 correlated negatively with Sox9 and gata4. Sox11 and Sox7 correlated negatively with gata4. Sox8 and Sox9 correlated positively with gata4. Therefore, the genome-wide identification and functional analysis of the Sox gene family will be useful to further reveal the functions of Sox genes in the Chinese soft-shell turtle.
