TLDR
It is proposed that NRT1.1 represses lateral root growth at low nitrate availability by promoting basipetal auxin transport out of these roots, which defines a mechanism connecting nutrient and hormone signaling during organ development.About:

Plant nitrogen assimilation and use efficiency.
TL;DR: The limiting factors in plant metabolism for maximizing NUE are different at high and low N supplies, indicating great potential for improving the NUE of current cultivars, which were bred in well-fertilized soil.
Journal ArticleDOI
Agricultural uses of plant biostimulants
TL;DR: There is growing scientific evidence supporting the use of biostimulants as agricultural inputs on diverse plant species, such as increased root growth, enhanced nutrient uptake, and stress tolerance.

Plasticity of the Arabidopsis Root System under Nutrient Deficiencies
TL;DR: A systematic comparison of RSA responses to nutrient deficiencies provides a comprehensive view of the overall changes in root plasticity induced by the deficiency of single nutrients and provides a solid basis for the identification of nutrient-sensitive steps in the root developmental program.
Journal ArticleDOI
Metabolic and signaling aspects underpinning the regulation of plant carbon nitrogen interactions
TL;DR: Recent advances in carbon/nitrogen metabolisms as well as sensing and signaling systems in illuminated leaves of C3-plants are discussed and a perspective of the type of experiments that are now required in order to take understanding to a higher level is provided.

Local, Efflux-Dependent Auxin Gradients as a Common Module for Plant Organ Formation
Eva Benková,Marta Michniewicz,Michael Sauer,Thomas Teichmann,Daniela Seifertová,Gerd Jürgens,Jiří Friml +6 more
TL;DR: It is shown that organ formation in Arabidopsis involves dynamic gradients of the signaling molecule auxin with maxima at the primordia tips, which suggest that PIN-dependent, local auxin gradients represent a common module for formation of all plant organs, regardless of their mature morphology or developmental origin.
Journal ArticleDOI
Aux/IAA proteins repress expression of reporter genes containing natural and highly active synthetic auxin response elements.
TL;DR: Cotransfection experiments with natural and synthetic AuxRE reporter genes and effector genes encoding Aux/IAA proteins showed that overexpression of Aux/ IAA proteins in carrot protoplasts resulted in specific repression of TGTCTC Auxre reporter gene expression.

The PIN auxin efflux facilitator network controls growth and patterning in Arabidopsis roots
Ikram Blilou,Jian Xu,Marjolein Wildwater,Viola Willemsen,Ivan A. Paponov,Jiří Friml,Renze Heidstra,Mitsuhiro Aida,Klaus Palme,Ben Scheres +9 more
TL;DR: This work shows that five PIN genes collectively control auxin distribution to regulate cell division and cell expansion in the primary root and reveals an interaction network of auxin transport facilitators and root fate determinants that control patterning and growth of the root primordium.
Journal ArticleDOI
Organization and cell differentiation in lateral roots of Arabidopsis thaliana
TL;DR: These studies show that organization and cell differentiation in the lateral root primordia precede the appearance of a lateral root meristem, with differential gene expression apparent after the first set of divisions of the pericycle.
