Abstract
Salt stress has been inimically affecting agricultural productivity through diminishing crop yield outputs and leading to food insecurities around the globe. These consequences are expected to be worsening by 2050 leading to 50% loss in the arable areas, causing soil infertility, and hence making them unsuitable for the crop sustenance. Therefore, to tackle salt-induced adversities, it is necessary to adapt profitable and environment friendly approaches to resolve the concerns related to crop health and survival in response to the underlying stressful circumstances. With this regard, green-synthesized gold nanoparticles (AuNPs) have been emerging as an area of immense interest to enhance crop sustainable production to improve plant acclimatizing competence in the challenging environments including salt stress. The present study discusses the significance of green-synthesized AuNPs in the antioxidant-mediated defense regulations to manage salt-induced oxidative injuries in mustard plants. In addition, AuNPs-mediated modulations in photosynthetic functioning, sugar and nitrogen metabolism along with stomatal behavior have significantly inhibited salt-induced abnormalities in mustard growth and physiology. Altogether, the study suggested the benefitted response of green-synthesized AuNPs, which could be bestowed as ‘growth stimulants’ under salt-challenged regimes to safeguard mustard plant responses with minimized yield penalties.
