Nitrogen Absorption in Plants (With Diagram)

Until recently, the reductive amination of 2-oxoglutarate catalyzed by the enzyme glutamate dehydrogenase has been considered as the main reaction of ammonia assimilation in plants. Now there is convincing evidence that most of the inorganic nitrogen available to a plant is incorporated into the amide amino group of glutamine via the enzyme glutamine synthetase (L-glutamate ammonia ligase— ADP, GS). Subsequently [...]
