Amino acids play several critical roles in plants, from providing the building blocks of
proteins to being essential metabolites interacting with many branches of metabolism. They …

Although amino acids are critical for all forms of life, only proteogenic amino acids that
humans and animals cannot synthesize de novo and therefore must acquire in their diets …

Glutamate occupies a central position in amino acid metabolism in plants. The acidic amino
acid is formed by the action of glutamate synthase, utilizing glutamine and 2-oxoglutarate …

Untargeted metabolomics aims to gather information on as many metabolites as possible in
biological systems by taking into account all information present in the data sets. Here we …

In cellular circumstances under which carbohydrates are scarce, plants can metabolize
proteins and lipids as alternative respiratory substrates. Respiration of protein is less …

High nitrogen (N) fertilization for maximizing crop yield commonly leads to postponed
flowering time (heading date in rice) and ripening, thus affecting resources use efficiency …

Cross-feeding interactions, in which bacterial cells exchange costly metabolites to the
benefit of both interacting partners, are very common in the microbial world. However, it …

Bacteria frequently exchange metabolites by diffusion through the extracellular environment,
yet it remains generally unclear whether bacteria can also use cell–cell connections to …

In a short time, plant metabolomics has gone from being just an ambitious concept to being
a rapidly growing, valuable technology applied in the stride to gain a more global picture of …

Bacillus sp B55, a bacterium naturally associated with Nicotiana attenuata roots, promotes
growth and survival of wild-type and, particularly, ethylene (ET)–insensitive 35S-ethylene …
