MicroRNAs Mediate Insecticide Tolerance in Spodoptera frugiperda

Project description:Spodoptera frugiperda is the world’s major agricultural pests, and has the distinctive features of high fecundity, strong migratory capacity and high resistance to most insecticides. At present, the control of S. frugiperda in China relies mainly on the spraying of chemical insecticides. MicroRNAs (miRNAs) are a class of small, single-stranded, non-coding RNAs, and play crucial regulatory roles in various physiological processes, including the insecticide resistance in insects. However, little is known about the regulatory roles of miRNAs on the resistance of S. frugiperda to insecticides. In the present research, the miRNAs that were differentially expressed after cyantraniliprole, spinetoram, emamectin benzoate and tetraniliprole treatment were analyzed by RNA-Seq. A total of 504 miRNAs were systematically identified from S. frugiperda, and 24, 22, 31 and 30 miRNAs were differentially expressed after treatments of cyantraniliprole, spinetoram, emamectin benzoate and tetraniliprole. GO and KEGG enrichment analyses were used to predict the function of differentially expressed miRNAs’ target genes. Importantly, ten miRNAs were significantly differentially expressed among the treatments of three insecticides. MiR-278-5p, miR-13b-3p, miR-10485-5p and miR-10483-5p were significantly down-regulated among the treatments of three insecticides by RT-qPCR. Furthermore, overexpression of miR-278-5p, miR-13b-3p, miR-10485-5p and miR-10483-5p significantly increased the mortality of S. frugiperda to cyantraniliprole and emamectin benzoate. The mortality was significantly increased with spinetoram treatment after overexpression of miR-13b-3p, miR-10485-5p and miR-10483-5p. These results suggest that miRNAs, which are differentially expressed in response to insecticides, may play a key regulatory role in the insecticide resistance in S. frugiperda.

Transcriptomic analysis the mechanism of detoxification metabolism induced by different insecticide in Spodoptera frugiperda

Project description: In order to clarify the molecular mechanism of metabolic detoxification in Spodoptera frugiperda, the enzyme activity assay and transcriptome sequencing analysis were used to screen and identify the relevant genes related to metabolic detoxification after induced by insecticides at LC50 dose.

Identification of differentially expressed miRNAs associated with diamide detoxification pathways in Spodoptera frugiperda

Project description:The fall armyworm (FAW) Spodoptera frugiperda is one of the most severe economic pests of multiple crops globally. Control of this pest is often achieved using insecticides; however, over time, S. frugiperda has developed resistance to new mode of action compounds, including diamides. Previous studies have indicated diamide resistance is a complex developmental process involving multiple detoxification genes. Still, the mechanism underlying the possible involvement of microRNAs in post-transcriptional regulation of resistance has not yet been elucidated. In this study, a global screen of microRNAs (miRNAs) revealed 109 known and 63 novel miRNAs. Nine miRNAs (four known and five novel) were differentially expressed between insecticide-resistant and -susceptible strains. Gene Ontology analysis predicted putative target transcripts of the differentially expressed miRNAs encoding significant genes belonging to detoxification pathways. Additionally, miRNAs are involved in response to diamide exposure, indicating they are probably associated with the detoxification pathway. Thus, this study provides comprehensive evidence for the link between repressed miRNA expression and induced target transcripts that possibly mediate diamide resistance through post-transcriptional regulation. These findings highlight important clues for further research to unravel the roles and mechanisms of miRNAs in conferring diamide resistance.

Identification and profiling of microRNAs in Zea mays in response to Spodoptera frugiperda feeding

Project description:MicroRNAs (miRNAs) are endogenous small noncoding RNAs (18–25 nt) that are involved in many physiological processes including development, cancer, immunity, apoptosis and host-microbe interactions through posttranscriptional regulation of gene expression. In this study, we measured the profile of small RNAs in Zea mays after one day and three days of Spodoptera frugiperda feeding. We identified 500 miRNAs, including 449 known and 51 novel miRNAs. In addition, we identified the miRNAs differentially expressed in Z. mays after one day and three days of S. frugiperda feeding, and the possible target genes were identified. This study identified critical miRNAs involved in the Z. mays during S. frugiperda feeding, thus providing a useful resource for exploring the regulatory role of miRNAs during plant-insect interactions.
