Since the 20th century, when plant resistance to aphids was available, it has been widely used by farmers and the inheritance of plant resistance has been understood for several crops. However, it is only when the plant-aphid relationship was compared with that of microbial pathogens, that aphid resistance has begun to be understood and integrated into the plant immune network. Three of the four genes identified for plant resistance to aphid encode nucleotide-binding site leucine-rich repeat receptor (NLR) proteins responsible for aphid-effector triggered immunity, and NLRs are serious candidates for aphid resistance in four other plant species. Aphids are vectors for plant viruses, and aphid-effectors triggering immunity when they pierce plant cells are expected to trigger resistance to the viruses transmitted to the plant with effectors, as has been shown for aphid resistance in melon. This dual phenotype increases the interest of NLRs in the control of aphids.
自20世纪植物对蚜虫产生抗性以来，农民们广泛利用这种抗性，并且已经了解了几种作物中植物抗性的遗传情况。然而，只有当将植物与蚜虫的关系与植物与微生物病原体的关系进行比较时，人们才开始理解蚜虫抗性并将其纳入植物免疫网络。已鉴定出的四种植物抗蚜虫基因中有三种编码核苷酸结合位点富含亮氨酸重复序列受体（NLR）蛋白，这些蛋白负责蚜虫效应子触发的免疫反应，并且NLR是其他四种植物物种中蚜虫抗性的重要候选者。蚜虫是植物病毒的传播媒介，正如甜瓜中的蚜虫抗性所显示的那样，当蚜虫效应子穿透植物细胞时触发免疫反应，有望引发对随效应子传播到植物上的病毒的抗性。这种双重表型增加了NLR在控制蚜虫方面的吸引力。
