坏死性真菌病原体用来侵染植物的策略通常被认为缺乏其吸器产生、寄主防御抑制、生物营养对应物的复杂程度。关于基于基因对基因的抗性反应如何对坏死性植物病原体起作用的知识也相对匮乏。然而，最近的数据来自一些系统，它们强调了特定种类的坏死(和/或半生物营养)真菌已经进化出非常复杂的植物感染策略，实际上，这些策略似乎劫持了通常对生物营养菌部署的寄主抗性反应。抗病(R)蛋白同源物和丝裂原活化蛋白激酶(MAPK)级联反应通常与不相容的抗病反应有关；在相容的疾病相互作用中，似乎是坏死性真菌的靶标。这些发现突显了坏死性真菌感染植物的策略正在出现的复杂性。
The strategies used by necrotrophic fungal pathogens to infect plants are often perceived as lacking the sophistication of their haustorium producing, host defence suppressing, biotrophic counterparts. There is also a relative paucity of knowledge regarding how effective gene-for-gene based resistance reactions might function against necrotrophic plant pathogens. However, recent data has emerged from a number of systems which has highlighted that particular species of necrotrophic (and/or hemibiotrophic) fungi, have evolved very sophisticated strategies for plant infection which appear, in fact, to hijack the host resistance responses that are commonly deployed against biotrophs. Both disease resistance (R) protein homologues and mitogen-activated protein kinase (MAPK) cascades commonly associated with incompatible disease resistance responses; appear to be targeted by necrotrophic fungi during compatible disease interactions. These findings highlight an emerging sophistication in the strategies deployed by necrotrophic fungi to infect plants.
