Overview of transcriptome sequence assembly. a The assembled 47,777 transcripts by mapping to domestic pig blasted to pig, mice and human, respectively. b Venn diagrams show the shared transcripts with orthologous transcripts to human, Mus musculus and pig genes. c Frequency distribution of the exon number (1 exon and 313 exons not included) and Trinity transcript length of assembled transcripts mapping to WZSP. X axis represented exon number and Y axis represented frequency of the exon number. d The assembled transcripts covered 20,248 in 20,326 protein-coding genes identified from the WZSP genome. e The identity of the transcript assembly–based domestic pig (47,777) and WZSP (45,614) reference genome. f The assembled 45,614 transcripts were annotated by blasting to WZSP, human, Mus musculus and cow
