The mTORC1 kinase is a master growth regulator that senses many environmental cues,
including amino acids. Activation of mTORC1 by arginine requires SLC38A9, a poorly …

Acetyl-CoA is a metabolite at the crossroads of central metabolism and the substrate of
histone acetyltransferases regulating gene expression. In many tissues fasting or lifespan …

Ever since the beginning of biochemical analysis, yeast has been a pioneering model for
studying the regulation of eukaryotic metabolism. During the last three decades, the …

As an essential plant macronutrient, the low availability of phosphorus (P) in most soils
imposes serious limitation on crop production. Plants have evolved complex responsive and …

Phosphorus is a crucial component of major organic molecules such as nucleic acids, ATP
and membrane phospholipids. It is present in soils in the form of inorganic phosphate (Pi) …

Arbuscular mycorrhizal fungi (AMF) occur in the rhizosphere and in plant tissues as obligate
symbionts, having key roles in plant evolution and nutrition. AMF possess endobacteria, and …

Intracellular inorganic orthophosphate (Pi) distribution and homeostasis profoundly affect
plant growth and development. However, its distribution patterns remain elusive owing to the …

Inorganic phosphate (Pi) is an essential component of all life forms. Land plants acquire Pi
from the soil through roots and associated symbioses, and it is then transported throughout …
