叶际微生物诱发气孔免疫的机制及其应用前景

Mechanism and Application Prospects of Plant Stomatal Immunity Induced by Phyllosphere Microbes

植物叶际微生物通过自身代谢活动影响植物功能的正常运行。而植物则可感应叶际微生物的存在,在诱发气孔免疫关闭以抵御病原菌入侵的同时,也降低了植物蒸腾作用,提高了其水分利用效率。对气孔免疫相关理论的研究有利于开发新型生物抗蒸腾剂,并对开发节水农业新技术具有重要意义。该文综述了叶际微生物与植物间的互作关系、气孔免疫及其免疫机制等方面的研究进展,并探讨了相关机制在节水农业方面的应用前景和重点研究方向。

Phyllosphere microbes may influence the functional properties of their host plants by their metabolic activities. Plants can sense the presence of phyllosphere microbes and then induce stomatal closure to prevent their invasion, which can reduce transpiration and improve water use efficiency. Theoretical research of stomatal immunity can help with the development of new biological anti-transpiration agents and water-saving agriculture. We here reviewed the progress in research into plant--phyllosphere microbe interactions as well as the phenomenon and mechanism of stomatal immu- nity and then discuss their application in water-saving agriculture and the need for future work.
