Comparing the assimilation of dietary nitrogen supplied by animal-, plant- and microbial-derived ingredients in Pacific white shrimp Litopenaeus vannamei: A stable isotope study

Aquaculture Reports, 2020
In order to become a more profitable and sustainable industry, the aquaculture sector is constantly exploring alternative nutrient sources. In the present study, the natural stable isotope signatures of different animal-, plant- and microbial-derived ...

Expression and analysis of StNR and StNiRs, key enzyme genes of nitrogen assimilation in potato (Solanum tuberosum L.) with different nitrogen efficiencies

Czech Journal of Genetics and Plant Breeding
The potato is a pivotal food crop on a global scale. Nitrate reductase (NR) and nitrite reductase (NiR) are the key enzymes in nitrogen assimilation. In previous research, we found that the nitrogen assimilation process was effectively regulated by StNR ...

Influence of Nitrogen Enrichment during Reproductive Growth Stage on Leaf Nitrogen Accumulation and Seed Yield in Soybean

Plant Production Science, 2014
Nitrogen assimilation during seed filling limits the seed yield in soybean. Seed nitrogen dependence on either redistributed nitrogen or absorbed nitrogen from soil during seed filling shows varietal differences.

Omeprazole Treatment Enhances Nitrogen Use Efficiency Through Increased Nitrogen Uptake and Assimilation in Corn

Frontiers in Plant Science, 2019
Omeprazole is a selective proton pump inhibitor in humans that inhibits the H+/K+-ATPase of gastric parietal cells. Omeprazole has been recently shown to act as a plant growth regulator and enhancer of salt stress tolerance.

Metabolic networks for nitrogen utilization in Prevotella ruminicola 23

Scientific Reports, 2017
Nitrogen metabolism in gut systems remains poorly studied in spite of its importance for microbial growth and its implications for the metabolism of the host. Prevotella spp. are the most predominant bacteria detected in the rumen, but their presence has

GlnR negatively regulates the transcription of the alanine dehydrogenase encoding gene ald in Amycolatopsis mediterranei U32 under nitrogen limited conditions via specific binding to its major transcription initiation site. [PDF]

PLoS ONE, 2014
Ammonium assimilation is catalyzed by two enzymatic pathways, i.e., glutamine synthetase/glutamate synthase (GS/GOGAT) and alanine dehydrogenase (AlaDH) in Amycolatopsis mediterranei U32.

Certain Environmental Conditions Maximize Ammonium Accumulation and Minimize Nitrogen Loss During Nitrate Reduction Process by Pseudomonas putida Y-9

Frontiers in Microbiology, 2021
Realizing the smallest nitrogen loss is a challenge in the nitrate reduction process. Dissimilatory nitrate reduction to ammonium (DNRA) and nitrate assimilation play crucial roles in nitrogen retention. In this study, the effects of the carbon source, C/

Nitrogen Assimilation in Mycorrhizas [PDF]

Plant Physiology, 1984
Ammonium assimilation was followed in N-starved mycelia from the ectomycorrhizal Ascomycete Cenococcum graniforme. The evaluation of free amino acid pool levels after the addition of 5 millimolar NH(4) (+) indicated that the absorbed ammonium was assimilated rapidly.

The regulatory mechanism of the low-nitrogen-responsive MADS-box transcription factor PpAGL24 in peach root system development and nitrogen utilization

Fruit Research
Nitrogen critically regulates peach yield formation and fruit quality development through multifaceted physiological mechanisms. In peach production, the problems of large nitrogen input and low Nitrogen Use Efficiency (NUE) are more prominent. Therefore,
