The transcriptome analysis of the whole-body of the gastropod mollusk Limax flavus and screening of putative antimicrobial peptide and protein genes.

The gastropod mollusk Limax flavus , one of the most widespread pests in China, is used to treat infectious diseases in traditional Chinese medicine. However, little genomic information is available for this non-model species. In this study, the whole-body transcriptome of L. flavus was sequenced using next generation sequencing technology. A total of 6.81 Gb clean reads were obtained, which were assembled into 150,766 transcripts with 132,206 annotated unigenes. Functionally classification assigned 30,542 unigenes to 56 Gene Ontology terms, 16,745 unigenes were divided into 26 euKaryotic Ortholog Groups of proteins categories, and 13,854 unigenes were assigned to 230 Kyoto Encyclopedia of Genes and Genomes pathways. Furthermore, we identified 17,251 simple sequence repeats and several kinds of antimicrobial peptide and protein (AMPs) genes. The transcriptome data of L. flavus will provide a valuable genomic resource for further studies on this species, and the AMPs identified in L. flavus will support its medical potential. • The gastropod mollusk Limax flavus is used to treat infectious diseases in traditional Chinese medicine. • Little genomic information is available for the non-model species L. flavus. • This study is the first whole transcriptome analysis of L. flavus. • It will help explore the genome of L. flavus and promote the medicinal use of L. flavus.
