在植物免疫四阶段模型的背景下，基因间相互作用获得了新的相关性。水稻 (Oryza sativa) 中已克隆了对亚洲稻瘿蚊 (Orseolia oryzae) 和小褐飞虱 (Nilaparvata lugens) 具有抗性的基因。导致植物抗性失效的昆虫无毒基因突变已被鉴定和克隆。结果与基因对基因假说和植物免疫的新模型一致。昆虫抗性基因编码具有核苷酸结合位点和富含亮氨酸重复序列的蛋白质。昆虫使用效应子来引发效应子触发的免疫。至少 7% 的 Hessian 果蝇基因是效应子编码。
Within the context of the four-phase model of plant immunity, gene-for-gene interactions have gained new relevance. Genes conferring resistance to the Asian rice gall midge (Orseolia oryzae) and the small brown planthopper (Nilaparvata lugens) have been cloned in rice (Oryza sativa). Mutations in insect avirulence genes that defeat plant resistance have been identified and cloned. Results are consistent with both the gene-for-gene hypothesis and the new model of plant immunity. Insect resistance genes encode proteins with nucleotide binding sites and leucine-rich repeats. Insects use effectors that elicit effector-triggered immunity. At least seven-percent of Hessian fly genes are effector encoding.
