Journal ArticleDOI
The role of glutamate dehydrogenase in plant nitrogen metabolism.
TL;DR: In vivo nuclear magnetic resonance spectroscopy, in vitro gas chromatography-mass spectrometry, and automated (15)N/(13)C mass spectromaetry have been used to demonstrate that glutamate dehydrogenase is active in the oxidation of glutamate, but not in the reductive amination of 2-oxogiutarate.
Journal ArticleDOI
Ammonium Assimilation and the Role of [gamma]-Aminobutyric Acid in pH Homeostasis in Carrot Cell Suspensions.
TL;DR: In vivo 15N NMR spectroscopy was used to monitor the assimilation of ammonium by cell-suspension cultures of carrot, demonstrating that cytoplasmic pH influences the pathways of intermediary nitrogen metabolism.
Journal ArticleDOI
Physiology of the interaction of angiosperm parasites and their higher plant hosts
TL;DR: Describing du phenomene de competition entre l'hote and le parasite, pour l'eau et les substances nutritives
Journal ArticleDOI
Regulation of glutamate dehydrogenase activity in relation to carbon limitation and protein catabolism in carrot cell suspension cultures.
TL;DR: Findings strengthen the view that the function of GDH is the catabolism of glutamate, which under conditions of carbon stress provides carbon skeletons for tricarboxylic acid cycle activity.
