Nickel-induced depression of nitrogen assimilation in wheat roots (2009, background): “Due to its lower affinity for ammonium, as compared to GS, GDH is not considered to take part in the primary ammonium assimilation (Dubois et al. 2003), but is rather believed to be involved in glutamate catabolism to provide carbon skeletons for the tricarboxylic acid cycle (Robinson et al. 1991).”
Physiology of maize I: A comprehensive and integrated view of nitrogen metabolism in a C4 plant (2005, background): “Although the role of GDH is still not clearly defined (Dubois et al. 2003), the enzyme activity gives an indication of the physiological status of a particular leaf in relation to its development stage and mode of N nutrition (Tercé-Laforgue et al.”
Do plants need nitrate? The mechanisms by which nitrogen form affects plants (2013, background): “There has been considerable debate in the scientific literature as to whether the enzyme can operate in vivo (Dubois et al., 2003; Labboun et al., 2009), in particular, under stress conditions (Skopelitis et al.”
Breeding for increased nitrogen‐use efficiency: a review for wheat (T. aestivum L.) (2016, background): “…studies performed on a number of model and crop species (Terc e-Laforgue et al. 2013) as well as quantitative genetic approaches performed on maize (Dubois et al. 2003) and wheat (Fontaine et al. 2009) strongly suggest that the reaction catalysed by NAD(H)-GDH is involved in the control of plant…”
Growth promotion of the freshwater microalga Chlorella vulgaris by the nitrogen-fixing, plant growth-promoting bacterium Bacillus pumilus from arid zone soils (2009, background): “are capable of growing without combined nitrogen for a limited time, as ammonium can be produced and recycled inside the organism by a variety of metabolic pathways, such as photorespiration, phenylpropanoid metabolism, use of nitrogen transport compounds, and amino acid catabolism [18].”
Can less yield more? Is reducing nutrient input into the environment compatible with maintaining crop production? (2004, background): “Other gene systems regulating N metabolism Although the GS/GOGAT enzymes are the primary routes of ammonium assimilation in plants, the physiological role of glutamate dehydrogenase (GDH) has been less clear [ 43 ].”
Effects of Ammonium Toxicity on Nitrogen Metabolism and Elemental Profile of Cucumber Plants (2007, background): “Asparagine synthetase has been proposed to constitute an alternative pathway for NH+4 assimilation under conditions where GS activity may not be sufficient (Dubois et al., 2003).”
Nitrogen Assimilation and its Relevance to Crop Improvement (2010, background): “Immunolocalization studies in Nicotiana tabacum, wheat and vine (Paczek et al., 2002; Dubois et al., 2003; Tercé-Laforgue et al., 2004b; Kichey et al., 2005) suggest that under certain circumstances, for example senescing leaves, flower receptacles and in epidermal root tip cells, the enzyme is…”
The Functional Organization and Control of Plant Respiration (2006, background): “Although the subject of some debate, it has been clearly demonstrated by means of 15 N- or 13 C-labelling experiments that the main function of Glu dehydrogenase is to deaminate Glu into 2-OG ( Dubois et al, 2003 ).”
