Glutamate dehydrogenase and glutamine synthetase activities in maize under water and salt stress
NADH-GDH activity from roots of maize plants subjected lo polyethyleneglycol (PEG) and salt stress decreased, rapidly after 12 h of treatment. GS activity did not diminish so markedly. In the First leaves, GS aclivity was surprisingly high when plants were subjected to both types of stress for 6 h....

| Resumo: | NADH-GDH activity from roots of maize plants subjected lo polyethyleneglycol (PEG) and salt stress decreased, rapidly after 12 h of treatment. GS activity did not diminish so markedly. In the First leaves, GS aclivity was surprisingly high when plants were subjected to both types of stress for 6 h. There where clear differences in the isoenzymatic patterns of GDH in extracts from stressed and control plants. The response of GDH activity to a secondary in vitro stress, induced by adding PEG to the extracts, was different in planls under wather or salt stress. |
