Summary: | Exorista civilis Rondani (Diptera:Tachinidae) is an excellent dominant parasitic enemy all over the world. But there has been a lack of research on the molecular regulation of diapause in E. civilis. To investigate the important diapause‐associated genes and metabolic pathways in E. civilis, we can provide a theoretical basis for clarifying the molecular mechanism of diapause at the transcriptome level. The Illumina HiSeq. 2000 platform was used to perform transcriptome sequencing and bioinformatics analysis of the non‐diapause and diapause pupae of E. civilis. 58,050 unigenes were successfully assembled, in which 4355 upregulated and 3158 downregulated unigenes were differentially expressed. Moreover, by Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichments, 896 kinds of the differentially expressed genes were specifically analyzed and showed that diapause‐associated genes were related to be involved in the pathways of cold resistance, amino acid metabolism, and energy metabolism. Furthermore, these upregulated five genes showed the same trends of expression patterns between quantitative real‐time polymerase chain reaction and RNA‐Seq. This study provides a theoretical basis for the further study of the diapausing molecular mechanisms of E. civilis.
Induction of diapausing pupae and transcriptomic analysis for the diapause and non‐diapause pupae of the parasitic fly, Exorista civilis.
Research Highlights
The diapause‐associated genes were mainly involved in the pathways of cold resistance, amino acid metabolism, and energy metabolism.
The expression of phosphoenolpyruvate carboxykinase was downregulated, indicating that gluconeogenesis may be supressed. |
