通过引发植物免疫增强植物对病虫害的抗性是作物保护的一个有吸引力的概念，因为它提供了对病虫害的持久广谱保护。本文综述了植物免疫启动的分子、生化和表观遗传驱动因子的最新研究进展。我们回顾了最近的研究结果的感知和信号机制控制启动的植物胁迫代谢产物β-氨基丁酸。此外，我们回顾了表观遗传调控的长期维护的启动和讨论如何压力诱导的DNA低甲基化在转座因子的减少可以总理防御基因的证据。最后，我们研究了如何启动可以利用作物保护和阐明的机会和挑战，从拟南芥模型系统的研究成果转化为作物。
Enhancing plant resistance against pests and diseases by priming plant immunity is an attractive concept for crop protection because it provides long-lasting broad-spectrum protection against pests and diseases. This review provides a selected overview of the latest advances in research on the molecular, biochemical and epigenetic drivers of plant immune priming. We review recent findings about the perception and signalling mechanisms controlling the onset of priming by the plant stress metabolite β-aminobutyric acid. In addition, we review the evidence for epigenetic regulation of long-term maintenance of priming and discuss how stress-induced reductions in DNA hypomethylation at transposable elements can prime defence genes. Finally, we examine how priming can be exploited in crop protection and articulate the opportunities and challenges of translating research results from the Arabidopsis model system to crops.
