Abstract: Green gram (Vigna radiata L. Wilczek) is one of the important pulse crops in India belongs to the family Fabaceae. The production and productivity is severely affected by abiotic stresses like drought and salinity. Both control and transformed plants of green gram variety ‘IPM-02-03’ were evaluated for moisture stress. Soil moisture stress was imposed at the reproductive stage by withholding irrigation completely for 7 days. Morphological, physiological and biochemical parameters were evaluated for drought tolerance at 0th, 3rd and 7th days with 100%, 50% and 25% water holding capacity, respectively during drought stress. In almost all the cases under moisture stress, transgenic plants showed higher yield and 100 seed weight. Pigments like chlorophyll and carotenoids accumulation was drastically decreases with increase in moisture stress. Higher accumulation of proline and antioxidant enzymes in transgenic plants than control showed better survival in stress condition. The present study suggests that, over expression of TIP1 gene in transformed plant can enhance better survival under drought stress condition.
