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 …

In the context of a recent massive increase in research on plant root functions and their
impact on the environment, root ecologists currently face many important challenges to keep …

Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants
acquire inorganic N from the soil, mainly in the form of nitrate and ammonium. To date …

Plant growth-promoting rhizobacteria (PGPR) are the rhizosphere bacteria that can enhance
plant growth by a wide variety of mechanisms like phosphate solubilization, siderophore …

Nitrogen (N) and potassium (K) are essential macronutrients for plants growth; however, the
mechanism by which K mediates negative effects on ammonium-sensitive plants is still …

Put Theory into Practice Scarcity of natural resources, higher costs, higher demand, and
concerns about environmental pollution-under these circumstances, improving food supply …

In this review, recent developments and future prospects of obtaining a better understanding
of the regulation of nitrogen use efficiency in the main crop species cultivated in the world …

Nitrogen (N), one of the most important nutrients, limits plant growth and crop yields in
sustainable agriculture system, in which phytohormones are known to play essential roles in …

Background Plants can utilize two major forms of inorganic N: NO3−(nitrate) and NH4+
(ammonium). In some cases, the preference of one form over another (denoted as β) can …

This short review outlines the central role of glutamine synthetase (GS) in plant nitrogen
metabolism and discusses some possibilities for crop improvement. GS functions as the …
