Roots are a highly organised plant tissue consisting of different cell types with distinct developmental functions defined by cell identity networks. Roots are the target of some of the most devastating diseases and possess a highly effective immune system. The recognition of microbe- or plant-derived molecules released in response to microbial attack is highly important in the activation of complex immunity gene networks. Development and immunity are intertwined, and immunity activation can result in growth inhibition. In turn, by connecting immunity and cell identity regulators, cell types are able to launch a cell type-specific immunity based on the developmental function of each cell type. By this strategy, fundamental developmental processes of each cell type contribute their most basic functions to drive cost-effective but highly diverse and, thus, efficient immune responses. This review highlights the interdependence of root development and immunity and how the developmental age of root cells contributes to positive and negative outcomes of development-immunity cross-talk.
根是一种高度组织化的植物组织，由不同类型的细胞组成，这些细胞具有不同的发育功能，由细胞身份网络定义。根是一些最具破坏性疾病的目标，并且具有高度有效的免疫系统。识别微生物或植物衍生的分子，这些分子是对微生物攻击的反应释放的，对于激活复杂的免疫基因网络非常重要。发育和免疫是交织在一起的，免疫激活会导致生长抑制。反过来，通过连接免疫和细胞身份调节剂，细胞类型能够根据每个细胞类型的发育功能启动细胞类型特异性免疫。通过这种策略，每个细胞类型的基本发育过程都为驱动具有成本效益但高度多样化的、因此高效的免疫反应做出了自己最基本的贡献。这篇综述强调了根发育和免疫的相互依赖性，以及根细胞的发育年龄如何影响发育-免疫交叉对话的积极和消极结果。
