Identification of tissue-specific alternatively spliced isoforms. a Venn diagram shows numbers of tissue specific alternatively spliced isoforms. b Percentage of five AS types of specific alternatively spliced isoforms in each tissue. Common represents the share isoforms of five tissues. c GO analysis of specific alternatively spliced isoforms in peg tissue. The top 15 GO terms are shown. The Y-axis on the left represents GO terms, and the X-axis indicates the “Rich factor” represented by the ratio of specific isoform numbers to total annotated isoform numbers of each term. The area of a circle represents specific isoform number. The lower the p-value, the more significant the enrichment. d The distributions of maximal tissue specificity scores (Jensen–Shannon, JS scores) for isoforms in the three categories
