General Information

EC Number General Information Comment Organism
2.7.2.8 physiological function the enzyme plays a vital role in enhancing drought tolerance by likely affecting the arginine and nitric oxide accumulation. The enzyme is involved in different strategies in response to drought stress. The ectopic expression of the maize enzyme in tobacco results in higher tolerance to drought compared to plants transformed with empty vector. Enzyme overexpression can enhance the activities of antioxidant defense enzymes, and decrease malondialdehyde content and leakage of electrolyte in tobacco under drought stress. Moreover, the transgenic tobacco accumulate more arginine and nitric oxide than control plants under drought stress Zea mays
