Ammonium is a major inorganic nitrogen source for plants. At low external supplies,
ammonium promotes plant growth, while at high external supplies it causes toxicity …

The yeast Saccharomyces cerevisiae has been a favorite organism for pioneering studies
on nutrient-sensing and signaling mechanisms. Many specific nutrient responses have been …

For organisms to coordinate their growth and development with nutrient availability, they
must be able to sense nutrient levels in their environment. Here, we review select nutrient …

In Arabidopsis the plasma membrane nitrate transceptor (transporter/receptor) NRT1. 1
governs many physiological and developmental responses to nitrate. Alongside facilitating …

Highlights•Root nitrate sensing is affected by rhizosphere pH and water availability.•Nitrate
transporters are involved in sensing cellular pH changes.•Root derived small mobile …

Fungi occupy diverse environments where they are constantly challenged by stressors such
as extreme pH, temperature, UV exposure, and nutrient deprivation. Nitrogen is an essential …

Signaling pathways that activate different mitogen-activated protein kinases (MAPKs) elicit
many of the responses that are evoked in cells by changes in certain environmental …

Root development is strongly affected by the plant's nutritional status and the external
availability of nutrients. Employing split-root systems, we show here that local ammonium …

During arbuscular mycorrhizal (AM) symbiosis, the plant gains access to phosphate (Pi) and
nitrogen delivered by its fungal symbiont. Transfer of mineral nutrients occurs at the interface …

All living organisms use numerous signal-transduction systems to sense and respond to
their environments and thereby survive and proliferate in a range of biological niches …
