Water pollution has become one of the most serious issues threatening water environments,
water as a resource and human health. The most urgent and effective measures rely on …

Gamma-aminobutyric acid (GABA) is a ubiquitous four-carbon, non-protein amino acid.
GABA has been widely studied in animal central nervous systems, where it acts as an …

Nitrate is an essential nutrient and signaling molecule for plant growth. Plants sense
intracellular nitrate to adjust their metabolic and growth responses. Here we identify the …

Chitosan in both native and degraded form (oligosaccharides) acts as a growth promoter
and generate responses associated with both primary and secondary metabolism in plants …

Plant growth and development has to be continuously adjusted to the available resources.
Their optimization requires the integration of signals conveying the plant metabolic status, its …

Background Nitrogen (N) is one of the key mineral nutrients for plants and its availability has
a major impact on their growth and development. Most often N resources are limiting and …

Nitrate is both a nitrogen source for higher plants and a signal molecule regulating their
development. In Arabidopsis, the NRT1. 1 nitrate transporter is crucial for nitrate signaling …

In plants, nitrate is not only a major nitrogen source but also a signalling molecule that
modulates the expression of a wide range of genes and that regulates growth and …

Nitrogen (N) and nitrate (NO3−) per se regulate many aspects of plant metabolism, growth,
and development. N/NO3− also suppresses parts of secondary metabolism, including …

Monocarpic senescence, characterized by whole-plant senescence following a single
flowering phase, is widespread in seed plants, particularly in crops, determining seed …
