摘要
植物中普遍存在的抗病机制有两种 ,即过敏反应 (HR)和系统获得性抗性 (SAR)。抗病基因(R )是决定寄主植物对病原物的专化性识别并激发抗病反应的基因 。
There are two types of mechanism of plant disease resistance, hypersensitive response (HR) and systemic acquired resistance (SAR). Disease resistance genes are determinant for the host that recognize the pathogeny specifically and trigger the resistant response complementing to avirulence genes of pathogeny.
