As an environmental stress factor, ultraviolet-B (UV-B) radiation directly affects the growth and development of Myzus persicae (Sulzer) (Homoptera: Aphididae). How M. persicae responds to UV-B stress and the molecular mechanisms underlying this adaptation remain unknown. Here, we analyzed transcriptome data for M. persicae following exposure to UV-B radiation for 30 min. We identified 758 significant differentially expressed genes (DEGs) following exposure to UV-B stress, including 423 upregulated and 335 downregulated genes. In addition, enrichment analysis using the Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases illustrated that these DEGs are associated with antioxidation and detoxification, metabolic and protein turnover, immune response, and stress signal transduction. Simultaneously, these DEGs are closely related to the adaptability to UV-B stress. Our research can raise awareness of the mechanisms of insect responses to UV-B stress.

桃蚜对 UV-B 胁迫的转录组分析

作为环境胁迫因素，紫外线-B（UV-B）辐射直接影响桃蚜（Sulzer）（同翅目：蚜科）的生长发育。M. persicae 如何对 UV-B 应激作出反应，以及这种适应背后的分子机制仍然未知。在这里，我们分析了暴露于 UV-B 辐射 30 分钟后 M. persicae 的转录组数据。我们在暴露于 UV-B 应激后鉴定了 758 个显着差异表达基因 (DEG)，其中包括 423 个上调基因和 335 个下调基因。此外，使用基因本体论和京都基因和基因组百科全书数据库的富集分析表明，这些 DEG 与抗氧化和解毒、代谢和蛋白质周转、免疫反应和压力信号转导有关。同时地，这些DEG与对UV-B胁迫的适应性密切相关。我们的研究可以提高人们对昆虫对 UV-B 应激反应机制的认识。
