【摘要】 几丁质是昆虫的主要组成成分，由于几丁质不存在于植物和无脊椎动物中，被认为是环境友好型农药的设计靶标。几丁质合成酶B是几丁质合成路径中的最后一个关键酶，近些年已成为国内外研究的热点内容。根据国内外对昆虫几丁质合成酶B基因功能的研究，综述了几丁质合成酶B对几丁质合成的调控研究进展，包括时空表达特性、基因功能、基因在害虫防治中的研究、并对RNA干扰技术应用存在的问题及解决途径进行了展望。更多还原

【Abstract】 Chitin is the main component of insects, and its synthesis plays an important role in insect growth and metamorphosis. Because chitin does not exist in plants and invertebrates, it is considered to be a design target for environmentally friendly pesticides. Chitin synthase B is the last key enzyme in the chitin synthesis pathway, which has become a hot topic in recent years. Based on the author ’s own, domestic and foreign research on the function of insect chitin synthase B gene, this paper reviewd the research progress of chitin synthase B in the regulation of chitin synthesis Including temporal and spatial expression characteristics, gene function, gene research progress in pest control, and the problems and solutions of RNA interference technology application.更多还原
