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 …

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

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 …

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 …

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 …

Glutamine synthetase assimilates ammonium into amino acids, thus it is a key enzyme for
nitrogen metabolism. The cytosolic isoenzymes of glutamine synthetase assimilate …

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 …

Plant growth‐promoting bacteria (PGPB) and NO–3 availability both affect NO–3 uptake and
root architecture. The presence of external NO–3 induces the expression of NO–3 …
