Glutamine synthetase(GS)is the key enzyme in the assimilation of ammonium in higer plants.In this paper,progress of the studies on glutamine synthetase(GS)and its isoforms in higher plants is reviewed.The distribution,properties,physiological functions and molecular biology of GS and its isoforms are...
A glutamine synthetase gene from alfalfa (Medicago sativa) has been expressed in Escherichia coli after fusion of bacterial transcription and translation signals to a complete alfalfa glutamine synthetase coding sequence. Synthesis of the alfalfa glutamine synthetase enzyme in Escherichia coli was demonstrate...

In plants, the primary input of nitrogen (obtained from the soil or from symbiotic dinitrogen fixation) occurs through the assimilation of ammonia into organic form. Synthesis of glutamine (via glutamine synthetase) is the major, and possibly exclusive, route for this process, and there is little...

Plant cells resistant to glutamine synthetase inhibitors, made by genetic engineering of EP0242236 The invention relates to a DNA fragment containing a determined gene, the expression of which inhibits the antibiotic and herbicidal effects of Bialaphos and related products. It also relates to ...
The plants dry weight (DW), the nodule fresh weight (FW), the nitrogenase activity, the nodule glutamine synthetase (GS) and glutamate synthase (GOGAT) activities, as well as the leghemoglobin content and the amino acid in the stem were measured 28 days after inoculation. The highest DW of...
Glutamine synthetase (GS) is a key enzyme in nitrogen assimilation, which catalyzes the formation of glutamine from ammonia and glutamate. Plant GS isoforms are multimeric enzymes, recently shown to be decamers. The Arabidopsis genome encodes five cytosolic (GS1) proteins labeled as GLN1;1 through...
