摘要

环境胁迫对植物来说是一个持续的挑战，植物如何应对这些胁迫的关键决定因素是它们的营养状况，特别是必需营养素如硝酸盐（NO3-）的可用性。最近的研究揭示了硝酸盐信号通路与应激反应之间的复杂串扰。除了作为一种关键的常量营养素外，NO3-还作为一种信号分子，调节植物代谢和防御的各个方面。本文综述了硝酸盐信号与植物抗逆性之间的两层相互作用：通过相互关联的生理过程调节介导的间接串扰，以及通过特定调节蛋白介导的直接串扰。通过研究NO3-有效性如何影响胁迫反应，我们旨在为植物抗逆性的机制提供新的见解。这一认识对于促进更可持续的农业实践和提高作物在逆境条件下的生产性能具有重大潜力。

Shaping plant resilience through nitrate nutrition: Insights from the crosstalk between nitrate signaling and stress response

Environmental stresses are a constant challenge for plants and a key determinant of how plants respond to these stressors is their nutritional status, particularly the availability of essential nutrients such as nitrate (NO₃^-). Recent research has uncovered a complex crosstalk between nitrate signaling pathways and stress response. In addition to being a key macronutrient, NO₃^- acts as a signaling molecule that modulates various aspects of plant metabolism and defense. This review explores two layers of interaction between nitrate signaling and plant resilience: indirect crosstalk mediated by the regulation of interconnected physiological processes, and direct crosstalk via specific regulatory proteins. By examining how NO₃^- availability influences stress responses, we aim to provide new insights into the mechanisms underlying plant resilience. This understanding holds significant potential for promoting more sustainable agricultural practices and enhancing crop performance under stress conditions.

期刊介绍： The journal Plant Stress deals with plant (or other photoautotrophs, such as algae, cyanobacteria and lichens) responses to abiotic and biotic stress factors that can result in limited growth and productivity. Such responses can be analyzed and described at a physiological, biochemical and molecular level. Experimental approaches/technologies aiming to improve growth and productivity with a potential for downstream validation under stress conditions will also be considered. Both fundamental and applied research manuscripts are welcome, provided that clear mechanistic hypotheses are made and descriptive approaches are avoided. In addition, high-quality review articles will also be considered, provided they follow a critical approach and stimulate thought for future research avenues. Plant Stress welcomes high-quality manuscripts related (but not limited) to interactions between plants and: Lack of water (drought) and excess (flooding), Salinity stress, Elevated temperature and/or low temperature (chilling and freezing), Hypoxia and/or anoxia, Mineral nutrient excess and/or deficiency, Heavy metals and/or metalloids, Plant priming (chemical, biological, physiological, nanomaterial, biostimulant) approaches for improved stress protection, Viral, phytoplasma, bacterial and fungal plant-pathogen interactions. The journal welcomes basic and applied research articles, as well as review articles and short communications. All submitted manuscripts will be subject to a thorough peer-reviewing process.
