Unigenes towards the protein sequences of public databases. A total of 24,574 (43.05 ) unigenes were successfully annotated in no less than one of the queried databases (Table 3). Of which, 23,114 (40.50 ) and 13,488 (23.63 ) unigenes had homologous sequences in the Nr and Swiss-prot protein databases, respectively. Meanwhile, 12,434 (21.78 ), 15,157 (26.56 ), and 13,699 (24.00 ) unigenes might be annotated and classified within the GO, KOG, and KEGG databases, respectively (Table three). Specifically, 12,434 unigenes annotated in the GO database had been divided into three most important subcategories and assigned into 56 2nd GO terms (Figure S2), and 15,157 unigenes were effectively clustered into 25 KOG subcategories (Figure S3). Additionally, 13,699 (24.28 ) unigenes were grouped into six primary KEGG categories that involve 287 secondary pathways (Figure S4). three.three. Differential Expression Evaluation The levels of gene expression have been normalized working with the FPKM values. The distribution of gene expression levels was shown as a series of box plots (Figure 1A). About half on the genes had been identified to be expressed at incredibly low levels (0.1 FPKMs 1) or not expressed at all (0 FPKMs 0.1) within the gonads, and only a modest proportion was viewed as to become very expressed (FPKMs 60). To ensure if all gonad samples had been dependable, the gene expression patterns of testes and ovaries have been visualized through a heatmap employing the Pearson correlation coefficient as distance measure (Figure 1B). The correlation XIAP Formulation analysis clearly indicated that the samples had been classified into two big groups, representing testis and ovary, respectively.
