Salt and drought stress exhibits oxidative stress and modulated protein patterns in roots and leaves of date palm (Phoenix dactylifera L.)

The formation of new proteins under the influence harsh environmental conditions is a plant adaptation reaction. Two-year-old date palm tissue culture-derived plants from ‘Barhee’ grown in field were subjected to salt stress (70 g l-1 NaCl) and dehydration-induced by applying 70 polyethylene glycol or without irrigation withholding (0 l-1) for one month. soluble carbohydrate content increased response salinity treatment leaves compared control drought irrigation. Proline all treatments. Malondialdehyde hydrogen peroxide salinity. Salinity activity ascorbate peroxidase catalase enzyme. treatments abscisic acid, whereas indoleacetic acid level decreased. protein pattern roots one-dimensional polyacrylamide gel electrophoresis showed that led bands' appearance other proteins' disappearance. A comparison patterns between revealed relative intensity more associated with than drought. results may be clearing important molecular mechanism tolerance extreme stress.
