Abstract：
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.
摘要：
模式触发的免疫（PTI）反应是通过识别微生物来源的分子（称为微生物或病原体相关分子模式）或来自受损宿主细胞的分子（称为损伤相关分子模式）在植物细胞表面触发的。膜定位受体蛋白，被称为模式识别受体，对这种认可负责。尽管PTI的大部分机制都是保守的，就负责模式识别的成分而言，PTI响应的自然变异存在于物种内部和物种之间，激活反应，以及诱导的反应强度。这篇评论描述了关于这种变化的已知内容。我们讨论了如何测量PTI反应的变化，以及如何将这些知识用于控制植物病害和开发具有增强抗病性的植物品种。
