Fig. 5

Differential expression analysis of tissue comparisons between the breeding and post-breeding periods. Volcano plot of differentially expressed genes in the brain (a), testis (b) and upper jaw skin (c; spine for short in figure) are separately presented. The X axis represents differential fold-change (log2FC) of the differentially expressed genes (DEGs), and the Y axis represents the –log padj value of the DEGs. padj represents the adjusted P-value of the DEG, and 0.05 was set as the significance level. Significantly up-regulated DEGs in the breeding period compared with the post-breeding period are presented in red, whereas significantly down-regulated DEGs are shown in green. Non-significantly differentially expressed genes are presented in blue. d Venn diagram showing co-differentially expressed genes among different tissue comparisons in Leptobrachium boringii
