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 …

Nitrogen accounts for approximately 60% of the fertilizer consumed each year; thus, it
represents one of the major input costs for most nonlegume crops. Nitrate is one of the two …

Nutrient signalling integrates and coordinates gene expression, metabolism and growth.
However, its primary molecular mechanisms remain incompletely understood in plants and …

Nitrogen is an essential macronutrient for plant growth and basic metabolic processes. The
application of nitrogen-containing fertilizer increases yield, which has been a substantial …

Nitrogen (N) availability is a major factor determining plant growth and productivity. Plants
acquire inorganic N from the soil, mainly in the form of nitrate and ammonium. To date …

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 …

Crop productivity relies heavily on nitrogen (N) fertilization. Production and application of N
fertilizers consume huge amounts of energy, and excess is detrimental to the environment; …

Highlights•Myriad transporters ensures N uptake and its distribution throughout the
plant.•Distinct glutamine synthetase isoenzymes contribute to meet the N demand under …

Plants need to cope with multitudes of stimuli throughout their lifecycles in their complex
environments. Calcium acts as a ubiquitous secondary messenger in response to numerous …
