| 中文摘要:目前化学防治仍是植物保护的重要手段，化学杀虫剂通过参与昆虫自然选择，诱导其产生可遗传的基因突变，从而导致昆虫抗药性的增加，近年来随着杀虫剂的广泛使用，抗药性已成为植物保护领域亟需解决的重大问题。利用分子生物学手段对由基因变异引起的昆虫抗药性进行解析已成为可能，在现今大多数昆虫抗药性研究中，功能基因组技术已被广泛用于候选基因调控抗药性机制的研究。本文介绍了双元基因表达技术——GAL4/UAS技术、基因干扰技术——RNAi技术和基因编辑技术——CRISPR/Cas9技术这3种有助于阐明昆虫抗药性分子机制的功能基因组技术，综述了这3种功能基因组技术在近几年昆虫抗药性研究中的应用实例，讨论了其目前的发展状况及其优势和局限性，以期在完善的功能基因组技术支持下为昆虫抗药性研究取得更多突破性进展。 |

| Abstract:At present, chemical control is still the significant approach for plant protection. Chemical insecticides participate in natural selection of insects by inducing hereditary genetic mutations, resulting in an increase of insecticide resistance. With the wide applications of insecticides in recent years, the resistance has become a crucial problem that needs to be solved in the field of plant protection. It is now possible to use methods in molecular biology to analyze insecticide resistance caused by genetic mutations. Functional genome analysis technologies have been widely used in the study on the mechanism of candidate genes in regulating insecticide resistance. This article introduced three functional genomic techniques that helped clarify the molecular mechanisms of insecticide resistance:the binary gene expression technology-GAL4/UAS technology, the gene interference technology-RNAi technology and the gene editing technology-CRISPR/Cas9 technology. Meanwhile, this article reviewed the application examples for the three functional genomic techniques in insecticide resistance research in recent years, discussed the current development and their advantages and limitations, with a view to make more breakthrough progresses in the insecticide resistance research based on the comprehensive functional genomic technologies. |
