Pathogen recognition by plants results in the activation of signaling pathways that induce defense reactions. There is growing evidence indicating that epigenetic mechanisms directly participate in plant immune memory. Here, we discuss current knowledge of diverse epigenomic processes and elements, such as noncoding RNAs, DNA and RNA methylation, histone post-translational modifications, and chromatin remodeling, that have been associated with the regulation of immune responses in plants. Furthermore, we discuss the currently limited evidence of transgenerational inheritance of pathogen-induced defense priming, together with its potentials, challenges, and limitations for crop improvement and biotechnological applications.
植物通过识别病原体激活信号通路，从而诱导防御反应。越来越多的证据表明，表观遗传机制直接参与植物的免疫记忆。在这里，我们讨论了不同的表观基因组过程和元件（如非编码 RNA、DNA 和 RNA 甲基化、组蛋白翻译后修饰以及染色质重塑）与植物免疫反应调控相关的最新知识。此外，我们还讨论了病原体诱导的防御启动的跨代遗传的有限证据，以及其在作物改良和生物技术应用方面的潜力、挑战和局限性。
