a Distributions of sequence read mapping of the E. granulosus genome, indicating similar patterns of exon and intron percentages. b Total distribution of 3904 genes with alternative splicing events in pepsin-treated groups. c Frequency distribution of five different modes of alternative splicing events in the early developmental stages of E. granulosus. NT Non-treated group, PEP pepsin-treated protoscoleces, 12Â h 12Â h after pepsin treatment, 24Â h 24Â h after pepsin treatment
