It is a well-established fact that nitric oxide (NO) is a multifaceted signaling molecule, which plays diverse role in organisms. In the past two decades, various pieces of evidence have been documented to address its involvement under various abiotic and biotic stress responses in plant systems. One of the prime consequences of abiotic stress is an increase in the cellular concentration of reactive oxygen species (ROS) and reactive nitrogen species such as nitric oxide (NO) peroxynitrite (ONOO), and nitrogen dioxide (NO₂). But how the pathways of these reactive oxygen species (ROS) and hormones are integrated with NO and how the signals are relayed in biological systems remain incoherent and scanty in the literature. Thus, this review attempts to address NO-mediated ROS metabolism, defense responses, and its interactions with other bioactive molecules.

众所周知，一氧化氮（NO）是一个多方面的信号分子，在生物中起着不同的作用。在过去的二十年中，已记录了各种证据来解决它在植物系统中受到各种非生物和生物胁迫反应的影响。非生物胁迫的主要后果之一是增加细胞内活性氧（ROS）和活性氮的浓度，例如一氧化氮（NO）过氧亚硝酸盐（ONOO）和二氧化氮（NO ₂）。但是，这些活性氧物质（ROS）和激素的途径如何与NO整合在一起，以及如何在生物系统中传递信号在文献中仍然缺乏连贯性和不足。因此，本综述试图解决NO介导的ROS代谢，防御反应及其与其他生物活性分子的相互作用。
