Naser A. Anjum,Iqbal Ahmad,Iram Mohmood,Mário Pacheco,Armando C. Duarte,Eduarda Pereira,Shahid Umar,Altaf Ahmad,Nafees A. Khan,Muhammad Iqbal,Majeti Narasimha Vara Prasad +10 more
TL;DR: In this paper, a review of recent studies on the modulation of total reduced GSH, GSH/GSSG redox couple, the major GSH-related enzymes and their cumulative significance in plants' adaptation and/or tolerance to TMs and metalloids in detail is presented.
Journal ArticleDOI
A new perspective of phytohormones in salinity tolerance: Regulation of proline metabolism
TL;DR: The present review focuses on enhancing understanding on the mechanism of salinity tolerance via proline and phytohormones with emphasis on phytOHormones interaction with proline under salinity stress.
Journal ArticleDOI
Nitrogen availability regulates proline and ethylene production and alleviates salinity stress in mustard (Brassica juncea).
TL;DR: Nitrogen differentially regulates proline production and ethylene formation to alleviate the adverse effect of salinity on photosynthesis in mustard, suggesting that a regulatory interaction exists between ethylene, proline and N for salt tolerance.
Journal ArticleDOI
Salicylic acid supplementation improves photosynthesis and growth in mustard through changes in proline accumulation and ethylene formation under drought stress
TL;DR: In this article, Salicylic acid (SA) was used to protect the mustard (Brassica juncea L.) cultivar Pusa Jai Kisan subjected to moderate drought stress on the basis of growth and photosynthesis.
Journal ArticleDOI
Exogenous salicylic acid improves photosynthesis and growth through increase in ascorbate-glutathione metabolism and S assimilation in mustard under salt stress.
TL;DR: Treatment of salicylic acid (SA) alleviated the negative effects of salt stress and improved photosynthesis and growth through increase in enzymes of ascorbate-glutathione pathway which suggest that SA may participate in the redox balance under salt stress.
