Primary root growth in the absence or presence of exogenous NO3–was studied by a
quantitative genetic approach in a recombinant inbred line (RIL) population of Medicago …

Nitrate (NO 3−) is one of the most important sources of mineral nitrogen, which also serves
as a key signaling molecule for plant growth and development. To cope with nitrate …

Abstract The Medicago truncatula NIP/LATD (for Numerous Infections and
Polyphenolics/Lateral root-organ Defective) gene encodes a protein found in a clade of …

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 …

The high affinity nitrate transport system (HATS) plays an important role in rice nitrogen
acquisition because, even under flooded anaerobic cultivation when NH4+ dominates …

Protons in acid soil are highly rhizotoxic to plants, but the mechanism of tolerance of plants
to protons is largely unknown. Nitrate uptake by root cells is accompanied by the uptake of …

Nitrate uptake by plant cells requires both high-and low-affinity transport activities.
Arabidopsis thaliana nitrate transporter 1/peptide transporter family (NPF) 6.3 is a dual …

Nitrate is an important nutrient required for plant growth. It also acts as a signal regulating
plant development. Nitrate is actively taken up and transported by nitrate transporters (NRT) …

Up-regulation of the high-affinity transport system (HATS) for NO3− and stimulation of lateral
root (LR) growth are two important adaptive responses of the root system to nitrogen …

Root NO3− efflux to the outer medium is a component of NO3− net uptake and can even
overcome influx upon various stresses. Its role and molecular basis are unknown. Following …
