In natural habitats, plants are exploited by pathogens in biotrophic or necrotrophic ways. Concurrently, plants have evolved their defense systems for rapid perception of pathogenic effectors and begin concerted cellular reprogramming pathways to confine the pathogens at the entry sites. During the reorganization of cellular signaling mechanisms following pathogen attack, non-coding RNAs serves an indispensable role either as a source of resistance or susceptibility. Besides the well-studied functions of non-coding RNAs related to plant development and abiotic stress responses, previous and recent discoveries have established that non-coding RNAs like miRNAs, siRNAs, lncRNAs and phasi-RNAs can fine tune plant defense responses by targeting various signaling pathways. In this review, recapitulation of previous reports associated with non-coding RNAs as a defense responder against virus, bacteria and fungus attacks and insightful discussion will lead us to conceive innovative ideas to fight against approaching threats of resistant breaking pathogens.
在自然栖息地中，植物会受到病原体的生物营养或坏死方式的侵害。同时，植物已经进化出了它们的防御系统，以便快速感知病原体效应子，并开始协同的细胞重编程途径，以在入口处限制病原体。在病原体攻击后细胞信号机制的重组过程中，非编码 RNA 作为抗性或易感性的来源发挥着不可或缺的作用。除了与植物发育和非生物胁迫反应相关的众所周知的非编码 RNA 功能外，以前和最近的发现已经确立了非编码 RNA（如 miRNA、siRNA、lncRNA 和 phasi-RNA）可以通过靶向各种信号通路来精细调节植物防御反应。在这篇综述中，对与非编码 RNA 作为防御应答物对抗病毒、细菌和真菌攻击的相关先前报告的回顾和深入讨论，将引导我们构想出创新的思路，以应对抗药性突破病原体的逼近威胁。
