Abstract

Abstract: Penaeus japonicas is an important shrimp species, which is exposed to stressors including a variety of epidemic diseases. To date, little is known about the mechanisms involved in the response to white spot syndrome virus (WSSV) mediated by long non-coding RNAs (lncRNAs). A total of 6544 putative lncRNAs were identified in the hepatopancreas in P. japonicas, which provides a useful lncRNA reference resource for use in future studies. In addition, a total of 444 differentially expressed mRNAs and 457 differentially expressed lncRNAs were identified at 6, 12, and 24 h after WSSV infection in the hepatopancreas of P. japonicas . Functional enrichment analysis showed that the differentially expressed mRNAs were enriched in terms related to immune response and viral infectivity such as defense response, aminopeptidase activity, whereas the differentially expressed lncRNA partner genes were enriched in ubiquitin-dependent protein catabolic process, lipoprotein metabolic process, and antigen processing and presentation. Moreover, several lncRNAs were induced by WSSV infection, indicating these lncRNAs might participate in regulating many immune processes referring to their partner genes. Co-expression analysis of the lncRNAs and their partner genes identified some high lncRNA-mRNA correlations. These results suggest that WSSV stimulates the immune response in the hepatopancreas potentially through an important coding and non-coding gene network, thereby providing valuable information regarding non-coding responses to WSSV in Penaeus species. Highlights: Profiles of mRNAs and lncRNAs were reported after WSSV infection in P. japonicus . LncRNAs activated by WSSV infection were first reported. DE lncRNAs appear to play crucial roles in anti-WSSV infection.
