Portunus trituberculatus is an ideal model for elucidating crustacean genetic networks.Here we combined single molecule real-time(SMRT)sequencing and Illumina RNA-seq to characterize the coding genes,non-coding RNAs and pseudogenes and further to improve the genome annotation information of P.trituberculatus.In this study,we assembled 9 694 non-redundancy full-length transcripts,and 658 737 307-bp repetitive sequences were identified in the P.trituberculatus full-length transcriptome.We also predicted the P.trituberculatus genome structure based on full-length transcripts,including 18 602 genes,28 686 non-coding RNAs,1 407 pseudogenes,740 motif,and 26 434 domain.Meanwhile,14 460,10211,5412,7314,and 14 448 genes had significant matches with sequences in the NR,KOG,GO,KEGG,and TrEMBL database,respectively.Overall,our work firstly provided the long-read transcriptome and we believed that these data are very necessary to improve the annotation information of P.trituberculatus genome structure,and useful information for the future studies on evolution and physiological regulation of P.trituberculatus.
