植物对蚜虫危害的防御响应研究进展

Aphids are important worldwide economic pests. Besides causing damage by taking in plant nutrients, they can also indirectly transmit a variety of plant virus diseases during feeding, seriously affecting the yield and quality of crops. Using the defense mechanisms of plants against aphids is an environmentally friendly control method. This research mainly reviews the strategies of plants in defending against aphids, including constitutive defense and inducible defense, the conduction of aphid damage signals and their specificity, the antagonism and cooperation of various signal pathways, and the application status of aphid-resistant genes. It also discusses the existing problems and looks forward to the future development directions.

蚜虫是重要的世界性经济害虫,除通过摄取植物营养造成伤害外,在取食期间还可间接传播多种植物病毒病,严重影响作物的产量和质量。利用植物对蚜虫的防御机制控制蚜虫是一种环境友好型防治方法。本研究主要对植物防御蚜虫的策略,包括组成防御和诱导型防御、蚜虫危害信号的传导及其特异性、各信号途径的对抗与协作及抗蚜基因的应用现状进行了综述，探讨了存在的问题并对今后的发展方向进行了展望。
