The pattern‐triggered immunity (PTI) response is triggered at the plant cell surface by the recognition of microbe‐derived molecules known as microbe‐ or pathogen‐associated molecular patterns or molecules derived from compromised host cells called damage‐associated molecular patterns. Membrane‐localized receptor proteins, known as pattern recognition receptors, are responsible for this recognition. Although much of the machinery of PTI is conserved, natural variation for the PTI response exists within and across species with respect to the components responsible for pattern recognition, activation of the response, and the strength of the response induced. This review describes what is known about this variation. We discuss how variation in the PTI response can be measured and how this knowledge might be utilized in the control of plant disease and in developing plant varieties with enhanced disease resistance.

植物模式触发免疫反应的自然变异：研究、影响和应用

模式触发免疫（PTI）反应是在植物细胞表面通过识别微生物衍生的分子（称为微生物或病原体相关分子模式）或源自受损宿主细胞的分子（称为损伤相关分子模式）而触发。膜定位受体蛋白（称为模式识别受体）负责这种识别。尽管 PTI 的大部分机制是保守的，但就负责模式识别、反应激活和诱导反应强度的成分而言，PTI 反应在物种内部和物种之间存在自然变异。这篇评论描述了有关此变体的已知信息。我们讨论了如何测量 PTI 响应的变化，以及如何利用这些知识来控制植物病害和开发具有增强抗病性的植物品种。
