Abstract:
Stomata serve as the battleground between plants and plant pathogens. Plants can perceive pathogens, inducing closure of the stomatal pore, while pathogens can overcome this immune response with their phytotoxins and elicitors. In this review, we summarize new discoveries in stomata-pathogen interactions. Recent studies have shown that stomatal movement continues to occur in a close-open-close-open pattern during bacterium infection, bringing a new understanding of stomatal immunity. Furthermore, the canonical pattern-triggered immunity pathway and ion channel activities seem to be common to plant-pathogen interactions outside of the well-studied Arabidopsis-Pseudomonas pathosystem. These developments can be useful to aid in the goal of crop improvement. New technologies to study intact leaves and advances in available omics data sets provide new methods for understanding the fight at the stomatal gate. Future studies should aim to further investigate the defense-growth trade-off in relation to stomatal immunity, as little is known at this time.
摘要:
气孔是植物和植物病原体之间的战场。植物可以感知病原体,诱导气孔孔闭合,而病原体可以用它们的植物毒素和激发剂克服这种免疫反应。在这次审查中,我们总结了气孔-病原体相互作用的新发现。最近的研究表明,在细菌感染过程中,气孔运动持续以闭-开-闭-开模式发生,带来了对气孔免疫的新认识。此外,典型模式触发的免疫途径和离子通道活性似乎在经过充分研究的拟南芥-假单胞菌致病系统之外的植物-病原体相互作用中很常见。这些发展可以有助于作物改良的目标。研究完整叶片的新技术和可用组学数据集的进步为理解气孔门的斗争提供了新方法。未来的研究应旨在进一步研究与气孔免疫有关的防御-增长权衡,在这个时候鲜为人知。
