Plants fight microbial attacks using both constitutive and induced defenses which include RNA silencing, basal and highly specific resistance. Basal resistance (PTI, for PAMP Triggered Immunity) is very often mediated via the detection of pathogen-associated molecular patterns (PAMPs). However, adapted microbes express a suite of effector proteins that often act to suppress these defenses. Plants have evolved other receptors called resistance proteins (R proteins) that detect these pathogen effectors and activate strong defenses called Effector Triggered Immunity (ETI).

植物利用组成型和诱导型防御来抵抗微生物的攻击，包括RNA沉默、基础和高度特异性抗性。基础耐药（PTI，PAMP触发免疫）通常通过检测病原体相关分子模式（PAMP）介导。然而，适应的微生物表达了一套效应蛋白，这些效应蛋白通常会抑制这些防御。植物已经进化出称为抗性蛋白（R蛋白）的其他受体，它们检测这些病原体效应物并激活称为效应物触发免疫（ETI）的强大防御。
