植物对病原菌的防卫反应ＣｈｒｉｓＢｏｗｌｅｒ等植物与病原菌之间有亲和和不亲和两种类型的关系。不亲和关系（抗病寄主，无毒病原菌）常常表现过敏反应（在病原菌穿透位点局部植物细胞坏死），这种过敏反应可以阻止病原菌进一步扩展到其他细胞。在亲和反应（感病寄主，... Plant defense response to pathogens ChrisBowler and other plants and pathogens have affinity and incompatibility between the two types of relationship. Incompatibilities (disease-resistant hosts, non-toxic pathogens) often manifest anaphylactic reactions (local plant cell necrosis at sites of pathogen breakthrough) that prevent the pathogen from further spreading to other cells. In the affinity reaction (susceptible host, ...
