Identification of AS isoforms and lncRNA. a. The gene numbers involving AS events. SE: skipped exon; MX: mutually skipped exon; RI: retained intron; A5: alternative 5′ splice site; A3: alternative 3′ splice site; AF: alternative first exon; AL: alternative last exon. b. Distribution of the number of poly (A) sites per gene. c. Venn diagram of lncRNAs predicted by CNCI, Pfam, CPC, and PLEK methods. d. Proportions of four types of lncRNA
