Abscisic acid (ABA)-, stress-, and ripening-induced (ASR) proteins are reported to be involved in abiotic stresses. However, it is not known whether ASR genes confer drought stress tolerance by utilizing the antioxidant system. The findings of this study demonstrated TaASR1 function in drought/osmotic stress tolerance. TaASR1 conferred drought/osmotic stress tolerance through regulating the expression of stress-, and defense-associated genes and enhancing the antioxidant system, thus preventing plants from oxidative damage.
