Upregulation of genes encoding plastidic isoforms of antioxidant enzymes and osmolyte synthesis impart tissue tolerance to salinity stress in bread wheat.

ABSTRACT: Wheat genotype Kharchia is a donor for salt tolerance in wheat breeding programs worldwide; however, the tolerance mechanism in Kharchia is yet to be deciphered completely. To avoid spending energy on accumulating organic osmolytes and to conserve resources for maintaining growth, plants deploy sodium (Na⁺) ions to maintain turgor. The enhanced ability to tolerate excess ion accumulation and ion toxicity is designated as tissue tolerance. In this study, salt-tolerant wheat genotype (Kharchia 65) and sensitive cultivars (HD2687, HD2009, WL711) were exposed to vegetative stage salinity stress (for four weeks). Kharchia 65 showed better tissue tolerance to salinity than the other genotypes based on different physiological parameters. Gene expression and abundance of chloroplast loc
