During the past two decades, nitric oxide (NO) has evolved from a mere gaseous free radical to become a new messenger in plant biology with an important role in a plethora of physiological processes. This molecule is involved in the regulation of plant growth and development, pathogen defence and abiotic stress responses, and in most cases this is achieved through its interaction with phytohormones. Understanding the role of plant growth regulators is essential to elucidate how plants activate the appropriate set of responses to a particular developmental stage or a particular stress. The first task to achieve this goal is the identification of molecular targets, especially those involved in the regulation of the crosstalk. The nature of NO targets in these growth and development processes and stress responses remains poorly described. Currently, the molecular mechanisms underlying the effects of NO in these processes and their interaction with other plant hormones are beginning to unravel. In this review, we made a compilation of the described interactions between NO and phytohormones during early plant developmental processes (i.e. seed dormancy and germination, hypocotyl elongation and root development).
在过去二十年中，一氧化氮（NO）已从单纯的气态自由基演变为植物生物学中的一种新信使，在众多生理过程中发挥着重要作用。该分子参与植物生长发育、病原体防御和非生物胁迫反应的调控，并且在大多数情况下，这是通过其与植物激素的相互作用来实现的。了解植物生长调节剂的作用对于阐明植物如何针对特定发育阶段或特定胁迫激活适当的反应组合至关重要。实现这一目标的首要任务是确定分子靶点，尤其是那些参与调控相互作用的靶点。在这些生长发育过程和胁迫反应中，NO靶点的性质仍鲜为人知。目前，NO在这些过程中的作用及其与其他植物激素相互作用的分子机制正开始被揭示。在本综述中，我们汇编了在植物早期发育过程（即种子休眠与萌发、下胚轴伸长和根发育）中所描述的NO与植物激素之间的相互作用。
