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

Supply and behaviour of NH4 and NO3 in the soil and processes of release, mechanisms of
N uptake in plants, factors affecting NH4 and NO3 uptake, general features of N nutrition and …

The major route of nitrogen assimilation has been considered for many years to occur via
the reductive amination of α-oxoglutarate, catalysed by glutamate dehydrogenase. However …

Recent work on the development of herbicide-resistant crops is reviewed. Examples of the
introduction of herbicide resistance into crop plants by several different biotechnological …

Aspartate is the common precursor of the essential amino acids lysine, threonine,
methionine and isoleucine in higher plants. In addition, aspartate may also be converted to …

The discovery of glutamate synthases (EC 1.4. 1.13 and EC 1.4. 7.1) caused a major re-
assessment of the way in which ammonium is assimilated in bacteria and higher plants. The …

The subject is reviewed under the headings: NH3 assimilation reactions; amide
accumulation and its regulation during NH3 assimilation/detoxification; respiration and …

The enzyme acetolactate synthase (ALS) is the target enzyme for the sulfonylurea and
imidazolinone herbicides. We describe the isolation and characterization of the ALS genes …

Acetolactate synthase (ALS) inhibitors are among the most commonly used herbicides. They
fall into four distinct families of compounds: sulfonylureas, imidazolinones, triazolopyrimidine …
