General Information

General Information Comment Organism
metabolism leaves of seedling grown in light for seven days contain about twofold higher glutamine synthetase activity than etiolated leaves. In both light and dark grown seedlings, total glutamine synthetase, isoforms GS1 and GS2 activities decline with plant age with more pronounced effect in leaves of etiolated seedlings. Isoform GS2 declines at a much faster rate than isoform GS1. Exposure of etiolated seedlings to light markedly enhances GS1 and GS2 activity, which is not affected by cycloheximide. Photosynthetic inhibitor dichlorophenyl dimethyl urea inhibits light dependent appearance of glutamine synthetase Cenchrus americanus
