Soilless cultivation represent a valid opportunity for the agricultural production sector,
especially in areas characterized by severe soil degradation and limited water availability …

Anthropogenic activities are altering total nutrient loads to many estuaries and freshwaters,
resulting in high loads not only of total nitrogen (N), but in some cases, of chemically …

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 …

In plant cells, ammonium is considered the most convenient nitrogen source for cell
metabolism. However, despite ammonium being the preferred N form for microalgae, at …

Ammonium (NH4+) toxicity is an issue of global ecological and economic importance. In this
review, we discuss the major themes of NH4+ toxicity, including the occurrence of NH4+ in …

Nitrogen (N) deposition is impacting the services that ecosystems provide to humanity.
However, the mechanisms determining impacts on the N cycle are not fully understood. To …

The decade since the publication of the third edition of this volume has been an era of great
progress in biology in general and the plant sciences in particular. This is especially true …

Background Plants can utilize two major forms of inorganic N: NO3−(nitrate) and NH4+
(ammonium). In some cases, the preference of one form over another (denoted as β) can …

Current global nitrogen fertilizer use has reached approximately one hundred billion kg per
annum. In many agricultural systems, a very substantial portion of this applied nitrogen …

The NO3-transporter plays an important role in rice nitrogen acquisition and nitrogen-use
efficiency. Our previous studies have shown that the high affinity systems for nitrate uptake in …
