Abstract
Long non-coding RNAs (lncRNAs) represent the largest class of non-coding transcripts. They act a pivotal part in various insect developmental processes and stress responses. However, the investigation of lncRNA functions in insecticide resistant remains at an early phase. Herein, we conducted whole-transcriptome RNA sequencing for two cotton aphid (Aphis gossypii Glover) strains, i.e., insecticide-susceptible (SS) and spirotetramat-resistant (SR). We discovered 6059 lncRNAs in the RNA-Seq data, and 874 lncRNAs showed differential expression. In addition, 5 lncRNAs among 874 lncRNAs were predicted as targets of acetyl-CoA carboxylase (ACC). Reverse transcription real-time quantitative PCR (RT-qPCR) combined with RNA interference (RNAi) confirmed that selected ACC lncRNA was related to the expression of ACC. Moreover, we also identified two transcription factors, i.e., C/EBP and C/EBPzeta, that regulate the transcription level of ACC lncRNA. These results provide a good basis for the study of cotton aphid lncRNA functions in insecticide resistance development.
