However, the role of long noncoding RNAs (lncRNAs) of V. ceranae in its infection of the host remains poorly understood. Using lncRNA-seq data from the midguts of Apis mellifera workers at 7 and 10 days post-inoculation with V. ceranae (NcT1L and NcT2L groups), along with controls inoculated with spores (NcCKL group), we performed transcriptome-wide identification and structural characterization of lncRNAs. We identified lncRNAs in V. ceranae and analyzed the regulatory network of the differentially expressed lncRNAs (DElncRNAs). A total of 27 V. ceranae lncRNAs were identified in the midguts. The 19, 21, and 4 DElncRNAs were identified in the NcCKL vs. NcT1L, NcCKL vs. NcT2L, and NcT1L vs. NcT2L comparison groups. These DElncRNAs were predicted to regulate 26, 27, and 2 upstream/downstream genes. Furthermore, 15, 23, and 4 DElncRNAs were found to target 195, 211, and 94 miRNAs, which in turn targeted 204, 216, and 73 mRNAs into the respective comparisons. The ceRNA network prediction revealed that DElncRNAs, miRNAs and mRNAs form a complex regulatory network. This study presents the expression profile of lncRNAs during V. ceranae infection and highlights their potential regulatory functions in pathogenesis. Our findings provide new molecular insights into host-pathogen interactions at the RNA level and establish a foundation for developing targeted strategies to control nosemosis.PMID:42450809 | PMC:PMC13359526 | DOI:10.3390/ani16132102
