Root exudation is an important process determining plant interactions with the soil
environment. Many studies have linked this process to soil nutrient mobilization. Yet, it …

Glutamate occupies a central position in amino acid metabolism in plants. The acidic amino
acid is formed by the action of glutamate synthase, utilizing glutamine and 2-oxoglutarate …

Nitrogen is a limiting resource for plant growth in most terrestrial habitats since large
amounts of nitrogen are needed to synthesize nucleic acids and proteins. Among the 21 …

Proline fulfils diverse functions in plants. As amino acid it is a structural component of
proteins, but it also plays a role as compatible solute under environmental stress conditions …

The enzymatic controlled metabolic processes in cells occur at their optimized pH ranges,
therefore cellular pH homeostasis is fundamental for life. In plants, the nitrogen (N) source …

Amino acids are not only a nitrogen source that can be directly absorbed by plants, but also
the major transport form of organic nitrogen in plants. A large number of amino acid …

Among higher plants graminaceous species have the unique ability to efficiently acquire iron
from alkaline soils with low iron solubility by secreting phytosiderophores, which are …

Background For more than a century, crop N nutrition research has primarily focused on
inorganic N (IN) dynamics, building the traditional model that agricultural plants …

▪ Abstract Sugars and amino acids are generated in plants by assimilation from inorganic
forms. Assimilated forms cross multiple membranes on their way from production sites to …

Amino acid transporters are the main mediators of nitrogen distribution throughout the plant
body, and are essential for sustaining growth and development. In this review, we …
