Abstract	ABA is a key regulator of redox homeostasis in plants exposed to abiotic stress. Both endogenous and exogenous ABA can cause the generation of H 2 O 2 in plant cells or tissues. The ascorbate peroxidase enzyme scavenges H 2 O 2 and neutralizes it through the ascorbate-glutathione cycle. The relationships between ABA, H 2 O 2 and thylakoid bound ascorbate peroxidase was investigated in a drought tolerant and a sensitive wheat cultivar after exogenous treatment with ABA and H 2 O 2 by analysis of thylakoid bound ascorbate peroxidase transcript modulation. Differential response of the antioxidant system indicated genotype specific tolerance mechanism under stress in wheat crop.
