摘　　要：叶际微生物的定居、组成及其对宿主植物的益生和拮抗作用受到越来越多的关注。气孔不再被认为是微生物侵入植物的被动通道,而是植物先天免疫的一个重要组成部分,对植物气孔与微生物的免疫互作的分子机制研究也越来越详尽。本文综述了叶际微生物与植物的免疫互作机制,结合环境因素影响的气孔开闭振荡及其对作物的水分利用效率的影响研究,提出可利用植物气孔免疫过程中的气孔振荡行为来发展农业节水增产技术的观点。植物气孔-微生物免疫互作将成为分子生态与农业生态的交叉点和新焦点。Phyllosphere microbes have received much attention. More and more studies have been conducted to know about the microbes species and how they colonize and interact with plants. Stomata were considered as passive portal of entry for plant pathogenic bacteria. However, recent studies suggest that stomata can play an active role in restricting bacterial invasion as one part of the plant innate immune system. The paper has summarized recent developments in molecular ecology on stomata-based immunity. And on the base of reports on the relationship between stomata closure and plant water use efficiency, studies to develop crop water-saving and product- increasing technique by making use of the stomata-based defense are feasible. Plant stomata-pathogen interaction will become the next focus of molecular ecology and agricultural ecology.
