Abstract
The effect of water stress was on gene expression was studied in Pancratium maritimum L. and barley. And he following results were obtained: ??The growth of Pancratium and barley was reduced by water stress but improved by exogenous proline. Additionally, Gly and Glu also improved the growth of stressed barley seedlings. ??There were major similarities between proteomic changes in response to salt and mannitolstress, in addition to unique effects of each osmoticum in both Pancratium and barley. Proline regulated some stress responsive proteins similarly as salt and mannitolstress did. ??Free ubiquitin and ubiquitinated proteins were increased by water stress but the whole pathway was more stable under mannitolstress and was stabilized by exogenous proline in Pancratium but the expression of ubiquitin was not modified by the stress in barley. ??Antioxidant enzymes (catalase and peroxidase) in Pancratium were induced by both kinds of stress but some inhibition occurred at severe saltstress more apparently in the roots. This inhibition was partially alleviated by exogenous proline. They were slightly modified in barley by stress and neither has responded to exogenous proline. ??Dehydrins were constitutively expressed in Pancratium, upregulated by both salt and mannitol, and some were induced by proline. In barley, they were inducibly expressed in response to stress but not to proline. ??Heat chock cognate (HSC70) was constitutively expressed in both plants and slightly induced by stress. ??Rubisco was reduced by saltstress in Pancratium and barley but was restored by exogenous proline.
