Abstract:

This study analyzed the expression profiles of miRNAs in fifth-instar larvae and pupae of Cnaphalocrocis medinalis using high-throughput sequencing technology, and predicted the target genes of significantly differentially expressed miRNAs and performed functional enrichment analysis. In the miRNA library of fifth-instar larvae and pupae of C. medinalis, 44 miRNAs were present. There were 11 differentially expressed miRNAs between the fifth-instar larval and pupal libraries, with a total of 756 predicted target genes. Functional analysis of the target genes showed that these target genes were significantly enriched to 14 GO terms. This study not only provided miRNA expression profile and differential expression information during the development of fifth-instar larvae and pupae of C. medinalis, but also laid a foundation for the study of the function of miRNA in regulating insect development.

Key words: Cnaphalocrocis medinalis, miRNA, target gene
