Mar 18, 2010 · The use of nitrogen by plants involves several steps, including uptake, assimilation, translocation and, when the plant is ageing, recycling and remobilization. For crops, NUE has been defined as the grain yield per unit of nitrogen available from the soil, including nitrogen fertilizer.

May 1, 2022 · Nitrogen assimilation in plants. A: Diagram of N assimilation. B: Enzymes involved in N assimilation participate in different biological processes. The N assimilation-related enzymes in Arabidopsis, rice, maize, and wheat were summarized.
Sep 25, 2023 · 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.

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 ...
Jun 1, 2015 · Plants and fungi are the only eukaryotic organisms able to assimilate inorganic N. Aside from legumes, which can fix atmospheric N, plants use mainly nitrate in aerobic soils and ammonium in flooded wetland or acidic soils.

Jun 23, 2021 · Nitrogen is an important macronutrient for plant growth and development. Research has long been carried out to elucidate the mechanisms involved in nitrogen uptake, assimilation, and utilization in plants. However, despite recent advances, many of these mechanisms still are not fully understood.
Crop productivity relies heavily on nitrogen (N) fertilization. Production and application of N fertilizers consume huge amounts of energy, and excess is detrimental to the environment; therefore, increasing plant N use efficiency (NUE) is essential for the development of sustainable agriculture.
