Abstract

The innate immunity of plants is a dynamic, multilevel system traditionally divided into pattern-triggered immunity (PTI) and effector-triggered immunity (ETI). Despite being activated by different types of receptors localized in different cell compartments, PTI and ETI are currently considered interdependent components of a single defense system. This view suggests that, due to various positive interactions between these two pathways, the innate immunity of plants is more than the sum of PTI and ETI. Available data indicate that PTI and ETI enhance each other synergistically, increasing the concentration of signaling molecules, such as components of kinase cascades, reactive oxygen species, calcium ions, and phytohormones. This leads to the activation of defense genes, providing a local response to pathogens and the development of systemic plant resistance.

植物先天免疫:信号通路的串扰
植物的先天免疫是一个动态的、多层次的系统,传统上分为模式触发免疫(PTI)和效应触发免疫(ETI)。尽管PTI和ETI被定位于不同细胞区室的不同类型的受体激活,但它们目前被认为是单一防御系统中相互依赖的组成部分。这一观点表明,由于这两种途径之间的各种正相互作用,植物的先天免疫大于PTI和ETI的总和。现有数据表明,PTI和ETI相互协同增强,增加信号分子的浓度,如激酶级联成分、活性氧、钙离子和植物激素。这导致防御基因的激活,提供对病原体的局部反应和系统植物抗性的发展。
