Application of chemical fertilizers, especially nitrogen (N), to crops has increased
dramatically in the last half century and therefore developing crop varieties with improved N …

All crops require nitrogen (N) for the production of a photosynthetically active canopy, whose
functionality will strongly influence yield. Cereal crops also require N for storage proteins in …

The literature on nitrogen (N) form effects on plants at different stages of their development
has been critically reviewed, assessing the possible mechanisms of these effects. In …

Overexpression of the cytosolic enzyme glutamine synthetase 1 (GS1) has been
investigated in numerous cases with the goal of improving crop nitrogen use efficiency …

Nitrogen fertilizer is the most used nutrient source in modern agriculture and represents
significant environmental and production costs. In the meantime, the demand for grain …

Nitrogen is one of the most important nutrients for tea plants, as it contributes significantly to
tea yield and serves as the component of amino acids, which in turn affects the quality of tea …

Glutamine synthetase (GS) is a key enzyme involved in the nitrogen metabolism of higher
plants. Abiotic stresses have adverse effects on crop production and pose a serious threat to …

More than 80% of land plant species can form symbioses with arbuscular mycorrhizal (AM)
fungi, and nutrient transfer to plants is largely mediated through this partnership. Over the …

Among three genes for cytosolic glutamine synthetase (OsGS1; 1, OsGS1; 2 and OsGS1; 3)
in rice (Oryza sativa L.) plants, the OsGS1; 2 gene is known to be mainly expressed in …

Inorganic nitrogen in the form of ammonium is assimilated into asparagine via multiple steps
involving glutamine synthetase (GS), glutamate synthase (GOGAT), aspartate …
