摘要

In the drought-tolerant rice cv. Lal nakanda, 95 steady-state high and low molecular weight proteins were identified which increased (such as those with molecular weights of 102, 100, 87, 85, 55, 44, 43.5, 43, 41.7, 39, 36, 32, 31, 29, 26, 24, 23.8,23, 21.5, 19, 18.2, 16.8 and 16.2 kDa in shoots and 100, 91, 87, 85, 81, 78, 63, 60, 52, 40.5, 31 and 26 kDa in roots) or decreased (such as those with molecular weights of 81, 58 and 10.2 kDa in shoots and 24, 22.5, 19, 16, 15.5, 15.2, 14.2 and 13.8 kDa in roots) when intact seedlings were subjected to salinity (NaCl), air drying or high and low temperatures. Several proteins (such as those with molecular weights of 100, 91, 87, 85 and 78 kDa) were found to be co-regulated in response to the above stresses. On the other hand, proteins specific to a given type of stress (such as 15 and 13 kDa in response to salinity; 60 and 10 kDa in response to desiccation; and 104, 93 and 76 kDa in response to high temperature) were also observed. Exogenous application of abscisic acid mimicked several of the protein perturbations caused by imposition of stress.
