▪ Abstract Nitrogen assimilation is a vital process controlling plant growth and development.
Inorganic nitrogen is assimilated into the amino acids glutamine, glutamate, asparagine, and …

The assimilation of inorganic nitrogen into organic form has marked effects on plant
productivity, biomass, and crop yield (Hageman and Lambert, 1988; Lawlor et al., 1989). As …

In the previous chapter we have outlined the pathways of nitrogen metabolism in higher
plants, with particular emphasis placed on the mechanisms by which ammonia is …

Studies of enzymes involved in nitrogen assimilation in higher plants have an impact on
both basic and applied plant research. First, basic research in this area should uncover the …

The assimilation of ammonia by a wide variety of organisms is the primary route for the
introduction of nitrogen into the biosphere. The assimilatory enzymes glutamine synthetase …

This short review outlines the central role of glutamine synthetase (GS) in plant nitrogen
metabolism and discusses some possibilities for crop improvement. GS functions as the …

Compared to other enzymatic systems, the regulation of GS isoenzyme expression shows a
unique diversity. Considering that GS is one of the oldest existing and functioning genes …

The majority if not all of the organic nitrogen in plants is derived from the assimilation of
ammonia into the amide position of glutamine by the enzyme glutamine synthetase (GS). A …

Ammonium is a form of inorganic nitrogen derived from several metabolic pathways, and is
assimilated into glutamine, glutamate, asparagine and carbamoylphosphate. These …

The field of amino acid biosynthesis from inorganic nitrogen has been one of the most active
in plant biochemistry in the last five years and a recent book has been devoted entirely to it …
