Phosphate Uptake by Phosphate-Starved Euglena

Phosphate Uptake by Phosphate-Starved Euglena

Phosphate participates in an essential way in a number of cell functions, including glycolysis, oxidative phosphorylation, and nucleic acid synthesis. In almost all the cell types studied, the entry of phosphate seems to be controlled at the cell surface (1). In yeast, in which phosphate can be transported against a concentration gradient, the accumulation of phosphate depends on glycolysis and...

Phosphate uptake by yeast cells

Metabolic adaptations of phosphate-starved plants.

Orthophosphate (Pi) is an essential macronutrient that plays a central role in virtually all major metabolic processes in plants, particularly photosynthesis and respiration. Many metabolites are Pi monoesters, whereas the phosphoanhydride bonds of compounds such asATP function to transfer energy from the energyyielding process of photo-, oxidative, and substratelevel phosphorylation to the ene...

High Phosphate Uptake

Human red blood cells reach an equilibrium of phosphate distribution at 37 ° much faster with o . I I M or intermediate levels than with o.o2 M and lower phosphate levels. Other divalent anions added to 0.o2 M phosphate solutions have an action similar to that of the extra phosphate. A past observation that phosphate escapes from red cells more slowly than it enters them appears to have arisen ...

Dissecting nutrient-related co-expression networks in phosphate starved poplars

Phosphorus (P) is an essential plant nutrient, but its availability is often limited in soil. Here, we studied changes in the transcriptome and in nutrient element concentrations in leaves and roots of poplars (Populus × canescens) in response to P deficiency. P starvation resulted in decreased concentrations of S and major cations (K, Mg, Ca), in increased concentrations of N, Zn and Al, while...
