Nitrogen assimilation - Wikipedia
Nitrogen assimilation is the formation of organic nitrogen compounds like amino acids from inorganic nitrogen compounds present in the environment. Organisms like plants, fungi and certain bacteria that can fix nitrogen gas (N 2) depend on the ability to assimilate nitrate or ammonia for their needs. Other organisms, like animals, depend ...
Nitrogen assimilation in plants: current status and future prospects
2022年5月1日 · In this review, we comprehensively summarize the progress on functionally characterized members of NR, NiR, GS, GOGAT, and other enzymes involved in N assimilation in three major crops—rice, maize, and wheat, also model plant Arabidopsis, and their application in improving NUE in crops was highlighted.
KEGG PATHWAY: Nitrogen metabolism - Reference pathway
The core nitrogen cycle involves four reduction pathways and two oxidation pathways. Nitrogen fixation [MD: M00175] is the process of reducing atmospheric molecular nitrogen to ammonia, a biologically useful reduced form incorporated into amino acids and other vital compounds.
Evolution and regulation of nitrogen flux through ... - Nature
2019年10月7日 · Using a combination of transcriptomics, proteomics, metabolomics, fluxomics, and flux balance analysis to examine short-term shifts in nitrogen utilization in the model pennate diatom in...
The pathway of nitrogen assimilation in plants - ScienceDirect
1976年1月1日 · Abstract-The major route of nitrogen assimilation has been considered for many years to occur via the reductive amination of x-oxoglutarate, catalysed by glutamate dehydrogenase.
Plant nitrogen assimilation and its regulation: a complex puzzle …
2015年6月1日 · Transport and enzymatic steps involved in primary nitrogen assimilation. Nitrate and ammonium are taken up by the root via specific transporters. Nitrate is reduced in the cytosol to nitrite by nitrate reductase (NR). A side reaction of NR produces nitrogen oxide (NO).
Nitrogen uptake, assimilation and remobilization in plants: …
The availability of carbon skeletons for ammonium condensation and the supply of ATP, Fdx and NADH as products of photosynthesis, respiration and photorespiration pathways are thus essential for nitrogen assimilation. NITROGEN REMOBILIZATION: A KEY FACTOR FOR NITROGEN USE EFFICIENCY Nitrogen remobilization and yield dilemma
Nitrogen Journey in Plants: From Uptake to Metabolism, Stress
2023年9月25日 · Plants uptake and assimilate nitrogen from the soil in the form of nitrate, ammonium ions, and available amino acids from organic sources. Plant nitrate and ammonium transporters are responsible for nitrate and ammonium translocation from the soil into the roots.
Transcriptional regulation of nitrogen-associated metabolism ... - Nature
2018年10月24日 · Here we present a transcriptional regulatory network and twenty-one transcription factors that regulate the architecture of root and shoot systems in response to changes in nitrogen availability....
Nitrogen assimilation in plants: current status and future ... - PubMed
NUE of crops is determined by N uptake, transport, assimilation, and remobilization. In the process of N assimilation, nitrate reductase (NR), nitrite reductase (NiR), glutamine synthetase (GS), and glutamine-2-oxoglutarate aminotransferase (GOGAT, also known as glutamate synthase) are the major enzymes.
