Nitric oxide (NO) is integral to modulating a wide array of physiological processes in plants, chiefly through its interactions with phytohormones. This review explores the complex dynamics between NO with four principal phytohormones: abscisic acid (ABA), salicylic acid (SA), auxin, and jasmonic acid (JA). The primary focus is on NO-mediated reversible redox-based modifications with a specific emphasis on S-nitrosylation. The impact of NO-induced S-nitrosylation is profound as it regulates crucial proteins involved in hormone signaling pathways, thereby influencing their synthesis, stability, and functional activity. The review elucidates how NO-mediated S-nitrosylation orchestrates the activities of ABA, SA, auxin, and JA under varying stress conditions and developmental stages. By modulating these phytohormones, NO effectively directs plant responses to a spectrum of biotic and abiotic stresses. This comprehensive review synthesizes current knowledge on highlights the essential role of NO in the regulation of hormonal networks and provides a comprehensive understanding of how S-nitrosylation facilitates plant adaptation and enhances stress resilience.
一氧化氮（NO）在调节植物的多种生理过程中不可或缺，主要是通过其与植物激素的相互作用来实现。本综述探讨了NO与四种主要植物激素：脱落酸（ABA）、水杨酸（SA）、生长素和茉莉酸（JA）之间的复杂动态关系。主要关注的是基于可逆氧化还原的NO介导修饰，特别强调S-亚硝基化。NO诱导的S-亚硝基化影响深远，因为它调节参与激素信号通路的关键蛋白质，从而影响其合成、稳定性和功能活性。该综述阐明了在不同的胁迫条件和发育阶段，NO介导的S-亚硝基化如何协调ABA、SA、生长素和JA的活性。通过调节这些植物激素，NO有效地引导植物对一系列生物和非生物胁迫作出反应。这篇全面的综述综合了当前的知识，突出了NO在激素网络调节中的重要作用，并全面理解了S-亚硝基化如何促进植物适应并增强胁迫恢复力。
