The visual deficiency symptoms developing on plants constitute the ultimate manifestation of
suboptimal nutrient supply. In classical plant nutrition, these symptoms have been …

Calcium is an essential element needed for growth and development of plants under both
non-stressed and stress conditions. It thereby fulfills a dual function, being not only an …

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 …

Adverse variations of abiotic environmental cues that deviate from an optimal range impose
stresses to plants. Abiotic stresses severely impede plant physiology and development …

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 (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 …

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 …

Soil composition largely defines the living conditions of plants and represents one of their
most relevant, dynamic, and complex environmental cues. The effective concentrations of …
