Salinity stress is one of the significant abiotic stresses that influence critical metabolic
processes in the plant. Salinity stress limits plant growth and development by adversely …

Background Nitrogen (N) is one of the key mineral nutrients for plants and its availability has
a major impact on their growth and development. Most often N resources are limiting and …

Nitrogen (N) is the main mineral element in plant tissues and almost all of this nutrient is
acquired from the soil by the roots. Nitrogen is available in many different forms in the soil …

In the majority of agricultural growing regions, crop production is highly dependent on the
supply of exogenous nitrogen (N) fertilizers. Traditionally, this dependency and the use of N …

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 …

In higher plants, two types of nitrate transporters, NRT1 and NRT2, have been identified. In
Arabidopsis, there are 53 NRT1 genes and 7 NRT2 genes. NRT2 are high-affinity nitrate …

Physiological measurements of nitrate (NO3−) uptake by roots have defined two systems of
high and low affinity uptake. In Arabidopsis, genes encoding both of these two uptake …

In the rhizosphere, exudates from plants and microorganisms as well as stable soil organic
matter influence processes that can control plant growth, microbial infections, and nutrient …

Under temperate climates and in cultivated soils, nitrate is the most important source of
nitrogen (N) available for crops and, before its reduction and assimilation into amino acids …

▪ Abstract Nitrate is the major source of nitrogen (N) for plants growing in aerobic soils.
However, the NO3− ion is also used by plants as a signal to reprogram plant metabolism …
