Summary of alternative splicing events and alternative polyadenylation events. a Alternative splicing events classification and number statistics. AS, alternative splicing; SE, skipping exon events; A5, 5′ splice sites events; A3, 3′ splice sites events; MX, mutually exclusive exons events; RI, retained intron events; AF, alternative first exons events; AL, alternative last exons events. b Distribution of genes that produce one or more splice isoforms. c Distribution of alternative splicing events in assembled chromosomes. d Distribution of the number of poly(A) sites per gene. e Relative frequency of each nucleotide around poly(A) cleavage sites. f The differentially expressed genes related to alternative splicing and alternative polyadenylation, the genes in red font are related to alternative polyadenylation, the genes in black font are related to alternative splicing
