Abstract
Several polypeptides were induced in leaves of Sesbania sesban var. bicolor under water stress (desiccation). Among them, the SDS-PAGE resolved a few high molecular mass polypeptides along with one major of 66 kDa. After boiling the total protein fraction, some low molecular mass polypeptides (10 – 30 kDa) as well as the one of 66 kDa remained stable. The latter (66 kDa) polypeptide is also regulated by exogenous application of ABA, indicating its significant role in adaptation of sesban to drought.
