Abstract 15 N-Nuclear magnetic resonance spectroscopy was used to follow nitrogen
assimilation and amino-acid production in Wolffia arrhiza (L.) Hork. ex. Wimmer, clone Golan …

Nitrogen assimilation and amino acid production in Spirodela oligorrhiza plants exposed to
30 mM 15 NH 4 Cl was studied using l5 N NMR spectroscopy. Green and etiolated plants …

Ammonia assimilation has been followed in ectomycorrhizal roots of Fagus sylvatica. The
absorption of ammonium ions was associated with a rapid synthesis of free amino acids in …

summary Nuclear magnetic resonance spectroscopy was used to monitor 15NH4+
assimilation and amino acid biosynthesis in the ectomycorrhizal basidiomycete Laccaria …

The high affinity of Lemna minor glutamine synthetase for ammonium (Kappm 1.2–1.5× 10−
5 M) and its strong inhibition by ADP and 5‐AMP contrasts with the low affinity (Kappm 3× …

Plants of duckweed (Lemna minor) were grown under constant illumination and with a
controlled supply of ammonium-N so as to maintain a constant low concentration. In two …

Lemna minor has the potential to assimilate ammonia via either the glutamine or glutamate
pathways. A 3-4 fold variation in the level of ferredoxindependent glutamate synthase may …

In Myrica gale L. plants the assimilation of ammonia released by symbiotic Frankia was
observed by 15N2 labelling and subsequent analysis of the isotopic enrichment of nodule …

Recent studies of nitrogen metabolism in higher plants suggest that ammonia assimilation
may take place through the combined operation of glutamine synthetase and glutamate …
