Screening TSGs and revealing genes related to male reproduction in the pig. a Distribution of the number of protein-coding genes in various pig tissues with different expression levels (log2 transformed FPKM). Note: colour code is palette = “paired”. b Distribution of the tissue specificity index (τ) of protein-coding genes across ten or nine (except testis) tissues is showed. The dotted line represents the value of the top 20% of the tissue specificity index scores. c Number of tissue-specific genes in the various tissues. d Boxplots show the expression level of TSGs in testis and nine other tissues. The significance level is determined using one-sided Wilcoxon rank-sum test (P < 2.00 × 10− 16). * P < 0.05; ** P < 0.01; *** P < 0.001. e GO analysis for TSGs. f Heat map showing the enriched gene sets for porcine TSGs based on hypergeometric distribution test.
