Similar to animal systems, plants have been suggested to possess both positive and antagonistic interactions between nitric oxide (NO) and melatonin. This review summarizes the current understanding of NO-melatonin crosstalk in plants with regard to redox homoeostasis, regulation of gene expression, and developmental changes. It also addresses the possible role of N-nitrosomelatonin (NOmela), which is likely to be associated with redox signaling and long-distance communication. Localization and quantification of NOmela are expected to add new insights into its precise role in plants. Methodological advances in imaging, isolation, and quantification of such a transient molecule require further attention. The quest for the biological role of NOmela in plants should lure physiologists to pursue investigations to obtain solid experimental evidence.
类似于动物系统，人们已经提出一氧化氮 (NO) 和褪黑素之间在植物中存在着相互促进和拮抗的作用。本综述总结了目前对植物中 NO-褪黑素相互作用的理解，包括氧化还原稳态、基因表达调控和发育变化。它还探讨了 N-亚硝酰基褪黑素 (NOmela) 的可能作用，NOmela 可能与氧化还原信号和长距离通讯有关。NOmela 的定位和定量有望为其在植物中的精确作用提供新的见解。对这种瞬态分子的成像、分离和定量的方法学进展需要进一步关注。对植物中 NOmela 的生物作用的探索应该吸引生理学家进行研究，以获得确凿的实验证据。
