Growth responses and differential expression of VrDREB2A gene at different growth stages of mungbean (Vigna radiata L. Wilczek) under drought stress.

ABSTRACT: Mungbean is an important pulse crop and is predominantly cultivated across Asia. However, its production is hampered by climate change-induced drought stress. Drought affects various morpho-physiological processes associated with growth and molecular functions. This study analyzed growth responses and VrDREB2A gene expression in two mungbean cultivars, DX208 and Tam Thanh Hoa under water deficit at vegetative and flowering stages. Water use and growth characters were evaluated at four time-points (8, 12, 15 and 20-day drought) and 7-day recovery while yield components and yield were recorded after harvesting. Differential expression of VrDREB2A gene was analyzed at four time-points for leaf and root. Plants used up water more quickly at the flowering stage than vegetative sta
