摘要
Nitric oxide is a major player in plant immune system In animals, nitric oxide (NO) functions as a ubiquitous signaling molecule involved in diverse physiological processes such as immunity. Recent studies provided evidence that plants challenged by pathogenic microorganisms also produce NO. The emerging picture is that NO functions as a signal in plant immunity and executes part of its effects through posttranslational protein modifications. Notably, the characterization of S-nitrosylated proteins provided insights into the molecular mechanisms by which NO exerts its activities. Based on these findings, it appears that NO is involved in both the activation and the negative control of the signaling pathways related to plant immunity.
