Phosphorus (P) is the second most essential macronutrient in terms of limiting plant growth. The genes involved in P acquisition, transport, storage, utilization and respective regulation have been extensively studied. In addition, significant attention has been given to the crosstalk between P and other environmental stresses. In this review, we summarize recent discoveries pertaining to the emerging function of P in plant immunity. The roles of external soil P availability, internal cellular P in plants, P starvation signaling machinery and phosphate transporters in biotic interactions are discussed. We also highlight the impact of several phytohormones on the signaling convergence between cellular P and immune responses. This information may serve as a foundation for dissecting the molecular interaction between nutrient responses and plant immunity.
就限制植物生长而言，磷（P）是第二重要的大量元素。参与磷获取、运输、储存、利用及各自调控的基因已得到广泛研究。此外，磷与其他环境胁迫之间的相互作用也受到了极大关注。在本综述中，我们总结了关于磷在植物免疫中新兴功能的最新发现。讨论了外部土壤有效磷、植物内部细胞磷、磷饥饿信号传导机制和磷酸盐转运蛋白在生物相互作用中的作用。我们还强调了几种植物激素对细胞磷信号与免疫反应之间信号汇聚的影响。这些信息可为剖析营养反应与植物免疫之间的分子相互作用奠定基础。
