BACKGROUND Many insect cytochrome P450 proteins (CYPs) are involved in the metabolic detoxification of exogenous compounds such as plant toxins and insecticides. Tribolium castaneum, the red flour beetle, is a major agricultural pest that damages stored grains and cereal products. With the completion of the sequencing of its genome, two T. castaneum species-specific CYP genes, CYP4BN6, and CYP6BQ11, were identified. However, it is unknown whether the functions of most CYPs are shared by TcCYP4BN6 and TcCYP6BQ11, and the upstream regulatory mechanism of these two CYPs remains elusive. RESULTS QRT-PCR analysis indicated that TcCYP4BN6 and TcCYP6BQ11 were both most highly expressed at the late pupal stage and were mainly observed in the head and gut, respectively, of adults. Moreover, the transcripts of these two CYPs were significantly induced by dichlorvos and carbofuran, and RNA interference (RNAi) targeting of each of them enhanced the susceptibility of beetles to these two insecticides. Intriguingly, knockdown of the latrophilin (lph) gene, which has been reported to be related to the insecticide susceptibility, reduced the expression of TcCYP4BN6 and TcCYP6BQ11 after insecticide treatment, suggesting that these two CYP genes are regulated by lph to participate in insecticide susceptibility in T. castaneum. CONCLUSION These results shed new light on the function and mechanism of CYP genes associated with insecticide susceptibility and could facilitate research on appropriate and sustainable pest control management. © 2019 Society of Chemical Industry.

CYP4BN6和CYP6BQ11介导杀虫剂敏感性,它们的表达受乳脂素在Tribolium castaneum中的表达调控。

背景技术许多昆虫细胞色素P450蛋白(CYP)参与外源化合物(例如植物毒素和杀虫剂)的代谢解毒。红粉甲虫Tribolium castaneum是一种主要的农业害虫,会破坏储存的谷物和谷类产品。完成其基因组测序后,鉴定了两个锥栗种特异性CYP基因CYP4BN6和CYP6BQ11。但是,尚不清楚大多数CYP的功能是否由TcCYP4BN6和TcCYP6BQ11共享,并且这两种CYP的上游调节机制仍然不清楚。结果QRT-PCR分析表明,TcCYP4BN6和TcCYP6BQ11都在p后期表达最高,主要在成年人的头部和肠道中观察到。而且,敌敌畏和呋喃丹显着诱导了这两种CYP的转录本,并且靶向它们的RNA干扰(RNAi)增强了甲虫对这两种杀虫剂的敏感性。有趣的是,据报导与杀虫剂敏感性有关的拉托菲林(lph)基因的敲低降低了杀虫剂处理后TcCYP4BN6和TcCYP6BQ11的表达,表明这两个CYP基因受lph调控,参与杀虫剂敏感性的研究。锥栗 结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。靶向它们的RNA干扰(RNAi)增强了甲虫对这两种杀虫剂的敏感性。有趣的是,据报导与杀虫剂敏感性有关的拉特洛林(lph)基因的敲低降低了杀虫剂处理后TcCYP4BN6和TcCYP6BQ11的表达,这表明这两个CYP基因受lph调控,参与了杀虫剂敏感性的研究。锥栗 结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。靶向它们的RNA干扰(RNAi)增强了甲虫对这两种杀虫剂的敏感性。有趣的是,据报导与杀虫剂敏感性有关的拉特洛林(lph)基因的敲低降低了杀虫剂处理后TcCYP4BN6和TcCYP6BQ11的表达,这表明这两个CYP基因受lph调控,参与了杀虫剂敏感性的研究。锥栗 结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。据报道,这与杀虫剂敏感性有关,在杀虫剂处理后降低了TcCYP4BN6和TcCYP6BQ11的表达,这表明这两个CYP基因受lph调控而参与了锥栗木的杀虫剂敏感性。结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。据报道,这与杀虫剂敏感性有关,在杀虫剂处理后降低了TcCYP4BN6和TcCYP6BQ11的表达,这表明这两个CYP基因受lph调控而参与了锥栗木的杀虫剂敏感性。结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。结论这些结果为CYP基因与杀虫剂敏感性相关的功能和机制提供了新的思路,并可能促进对适当和可持续的害虫控制管理的研究。©2019化学工业协会。
