Bombyx mori nucleopolyhedrovirus (BmNPV) is a major pathogen that threatens the growth and sustainability of the sericultural industry. Currently, accumulated studies showed that long non-coding RNAs (lncRNAs) play important roles in the genesis and progression of various viruses and host-pathogens interactions. However, the functions and regulatory mechanisms of lncRNAs in insect-virus interaction are still limited. In this study, transcriptome sequencing and ribosome profiling sequencing (Ribo-seq) were performed in the BmNPV-infected midgut and control tissue, and a total of 9 differentially expressed (DE) lncRNAs and 27 small ORFs (sORFs) with micropeptide coding potential were identified. Among them, lncRNA XR_001139971.3 (lnc557) is verified to be significantly up-regulated upon BmNPV infection and may have the potential to encode a small peptide (ORF-674). The subcellular localization experiment showed that lnc557 was expressed in the cytoplasm. Overexpression of lnc557 promotes BmNPV replication and vice versa. By combining RNA pull-down, mass spectrometry, protein truncation and RNA immunoprecipitation (RIP) assays, we confirmed that lnc557 can bind to the RRM-5 domain of BmELAVL1 protein. Subsequently, we found that lnc557 could promote the expression of BmELAVL1 by enhancing the stability of BmELAVL1. Further, enhancing the expression of BmELAVL1 can promote the proliferation of BmNPV, while knockdown shows the opposite effect. Our data suggest that lnc557-mediated BmELAVL1 expression enhancement could play a positive role in BmNPV replication, which will provide a new insight into the molecular mechanism of interaction between Bombyx mori and virus.
