Exogenous AsA Coordinates Carbon and Nitrogen Metabolism and Enhances Drought Tolerance in Upland Rice ( Oryza sativa L.) by Activating the AsA–GSH Cycle
Prolonged drought leads to excessive accumulation of reactive oxygen species, damage to photosystems and an imbalance in carbon and nitrogen metabolism, thereby limiting the reproductive growth and yield potential of drought‐stressed rice ( Oryza sativa L .). The Ascorbate–Glutathione Cycle is a key metaboli...
