　　保卫细胞可整合多种复杂的环境信号并通过气孔的开闭调节以适应环境变化。研究已证明一氧化氮（NO）作为信号分子介导脱落酸（ABA）诱导的气孔关闭和 ABA 抑制的气孔开放。讨论了植物中 NO 的产生及其信号作用，NO 诱导的基因表达以及其与植物抗逆之间的可能作用机制；关注保卫细胞中 NO 与 ABA 信号级联的节点。对于保卫细胞中 NO 与 ABA 信号作用的研究将为通过提高植物水分利用效率而增强植物的抗旱性的生物技术提供理论基础。

Guard cells can integrate multiple complex signals from the environment and respond by opening and closing stomata in order to adapt to environment. Considerable research progress has been made in our understan-ding of the role of NO(nitric oxide) as essential signal molecules that mediate abscisic acid(ABA)-induced stomatal closure or inhibited stomatal opening. In this review,we discuss NO generation and signalling,NO-induced gene expression,crosstalk and the specificity between ABA and NO signalling,and the cellular mechanism for NO sensing in guard cells. This review focuses especially on the points of connection between ABA and NO signalling in guard cells. The fundamental progress in understanding the role of ABA and NO in guard cells will continue to provide a rational basis for biotechnological improvements in the development of drought-tolerant crop plants with improved water-use efficiency.
