The Green Revolution of the 1960s improved crop yields in part through the widespread
cultivation of semidwarf plant varieties, which resist lodging but require a high-nitrogen (N) …

BACKGROUND Although plants are dependent on the capture of a number of elemental
nutrients from the soil, the principal nutrients that limit plant productivity are nitrogen (N) and …

In order to optimally establish their root systems, plants are endowed with several
mechanisms to use at distinct steps during their development. In this review, we zoom in on …

Optimal plant development requires root uptake of 14 essential mineral elements from the
soil. Since the bioavailability of these nutrients underlies large variation in space and time …

Nitrogen (N) is an essential macronutrient that affects plant growth and development. N is an
important component of chlorophyll, amino acids, nucleic acids, and secondary metabolites …

Nitrogen availability is a major factor determining plant growth and productivity. Plants
acquire nitrogen nutrients from the soil through their roots mostly in the form of ammonium …

Plants uptake nitrogen (N) from the soil mainly in the form of nitrate. However, nitrate is often
distributed heterogeneously in natural soil. Plants, therefore, have a systemic long-distance …

Nitrogen (N) is a critical nutrient for plants but is often distributed unevenly in the soil. Plants
therefore have evolved a systemic mechanism by which N starvation on one side of the root …

Plants have developed adaptive responses allowing them to cope with nitrogen (N)
fluctuation in the soil and maintain growth despite changes in external N availability. Nitrate …
