Great strides have been made in defining the details of the plant defense response involving biotrophic fungal and bacterial pathogens. The groundwork for the current model was laid by H.H. Flor and others who defined the gene-for-gene hypothesis, which is now known to involve effector-triggered immunity (ETI). PAMP-triggered immunity (PTI) is also a highly effective response to most pathogens because of the recognition of common pathogen molecules by pattern recognition receptors. In this article, we consider the three pathogens that make up the foliar disease complex of wheat, , , and , to review the means by which necrotrophic pathogens circumvent, or outright hijack, the ETI and PTI pathways to cause disease.
在定义涉及生物亲和性真菌和细菌病原体的植物防御反应细节方面取得了重大进展。目前的模型基础是 H.H.弗洛尔等人建立的基因对基因假说，现在已知该假说涉及效应子触发免疫（ETI）。由于模式识别受体对常见病原体分子的识别，植物病原蛋白触发免疫（PTI）也是对大多数病原体的一种高度有效的反应。在本文中，我们考虑了构成小麦叶部病害复合体的三种病原体 、 、 和 ，以综述坏死型病原体规避或完全劫持 ETI 和 PTI 途径引起疾病的方式。
