The Arabidopsis nitrate transporter NPF7.3/NRT1.5 is involved in lateral root development under potassium deprivation.

Plant signaling & behavior - 3 May 2016

Zheng Yue, Drechsler Navina, Rausch Christine, Kunze Reinhard

Abstract excerpt

Plants have evolved a large array of transporters and channels that are responsible for uptake, source-to-sink distribution, homeostasis and signaling of nitrate (NO3(-)), which is for most plants the primary nitrogen source and a growth-limiting macronutrient. To optimize NO3(-) uptake in response to changing NO3(-) concentrations in the soil, plants are able to modify their root architecture. Potassium is...
