Microorganisms are able to utilize nitrogen (N) from a wide range of organic and mineral
compounds. In this paper, we review the current knowledge about the regulation of the …

Ammonium is one of the most important nitrogen sources for bacteria, fungi, and plants, but it
is toxic to animals. The ammonium transport proteins (methylamine permeases/ammonium …

In the symbiotic association of plants and arbuscular mycorrhizal (AM) fungi, the fungus
delivers mineral nutrients, such as phosphate and nitrogen, to the plant while receiving …

Although ammonium is the preferred nitrogen source for microbes and plants, in animal cells
it is a toxic product of nitrogen metabolism that needs to be excreted. Thus, ammonium …

The ammonium transport (Amt) family of proteins comprises a unique and ubiquitous group
of integral membrane proteins found in all domains of life. They are present in bacteria …

Efficient regulation of nitrogen metabolism likely plays a role in the ability of fungi to exploit
ecological niches. To learn about regulation of nitrogen metabolism in the rice blast …

External hyphae, which play a key role in nitrogen nutrition of trees, are considered as the
absorbing structures of the ectomycorrhizal symbiosis. Here, we have cloned and …

The proteins of the ammonium transporter/methylammonium permease/Rhesus factor family
(AMT/MEP/Rh family) are responsible for the movement of ammonia or ammonium ions …

Nutrient sensing plays important roles in fungal development in general, and specifically in
critical aspects of pathogenicity and virulence, for both animal and plant pathogens …

Proper regulation of metabolism is essential to maximizing fitness of organisms in their
chosen environmental niche. Nitrogen metabolite repression is an example of a regulatory …
