Enhancing nitrogen use efficiency (NUE) in crop plants is an important breeding target to
reduce excessive use of chemical fertilizers, with substantial benefits to farmers and the …

Nitrogen is essential for plant growth and crop productivity; however, nitrogen use efficiency
(NUE) decreases with increasing N supply, resulting in a waste of resources. Molecular …

The transmembrane transport of NO 3− and Cd 2+ into plant cell vacuoles relies on the
energy from their tonoplast proton pumps, V-ATPase and V-PPase. If the activity of these …

Aim: Heavy metal pollution is serious in China, and abscisic acid (ABA) is an important
stress hormone. How it regulates plant tolerance to cadmium remains unclear, so we aimed …

Nitrate, once taken up by plants, can either be stored in vacuoles or reduced by nitrate
reductase in the cytoplasm. High accumulation of NO 3− in the vacuole occurs when …

Wang, B. and Shen, QR 2011. NH 4+-N/NO 3−-N ratios on growth and NO 3−-N
remobilization in root vacuoles and cytoplasm of lettuce genotypes. Can. J. Plant Sci. 91 …

Abstract Nitrate (NO 3−) can accumulate in high concentrations in plant cell vacuoles if it is
not reduced, reutilized or transported into the cytoplasm. Such accumulation of NO 3− in the …

Large amount of N03--N are accumulated in vacuole, and cannot be timeously reducted,
reutilized and transported into cytoplasm. It is the main reason for great N03--N …

Abstract Nitrogen (N) is very important for chrysanthemum yield and quality. Nitrate (NO 3−)
is the main form of N absorbed by chrysanthemum. The NO 3− accumulated in the leaf …
