Green synthesis of nanoparticles (NPs) is competent in inducing physiological responses in plants for combating the abiotic stresses. Considering this, salt stress is one of the most alarming conditions that exerts complex and polygenic impacts on morph-physiological functioning of plants; resulting in reduced crop productivity and yield. Therefore, understanding the salt responses and tolerance mechanisms are important for sustaining crop productivity. In the current study, we have examined the effects of biosynthesized gold nanoparticles (AuNPs) on wheat (Triticum aestivum) plants under salt stress. Green-synthesized AuNPs were found beneficial in modulating the K⁺/Na⁺ ratio, chlorophyll concentration, defense systems, nitrogen assimilation, stomatal dynamics and growth traits under salt stress condition. Furthermore, the excessive accumulation of oxidative stress markers including reactive oxygen/nitrogen species was controlled in response of AuNPs treatment under salt stress. Overall, modulation of these traits commanded to induce salt stress tolerance in wheat plants.

纳米粒子 (NPs) 的绿色合成能够在植物中诱导生理反应以对抗非生物胁迫。考虑到这一点，盐胁迫是对植物形态生理功能产生复杂和多基因影响的最令人担忧的条件之一。导致作物产量和产量下降。因此，了解盐分反应和耐受机制对于维持作物生产力很重要。在目前的研究中，我们研究了生物合成金纳米粒子 (AuNPs) 对盐胁迫下小麦 ( Triticum aestivum ) 植物的影响。发现绿色合成的 AuNPs 有助于调节 K ⁺ /Na ⁺盐胁迫条件下的比例、叶绿素浓度、防御系统、氮同化、气孔动力学和生长特性。此外，在盐胁迫下，AuNPs 处理响应控制了包括活性氧/氮物质在内的氧化应激标志物的过度积累。总体而言，这些性状的调节命令诱导小麦植物的盐胁迫耐受性。
