Polyphosphate (polyP), a polymer of orthophosphate (PO4 3-) of varying lengths, has been
identified in all kingdoms of life. It can serve as a source of chemical bond energy …

There are a several molecules on Earth that effectively store energy within their covalent
bonds, and one of these energy-rich molecules is polyphosphate. In microbial cells …

Metal transporters are a central component in the interaction of algae with their environment.
They represent the first line of defense to cellular perturbations in metal concentration, and …

We identified a Cu-accumulating structure with a dynamic role in intracellular Cu
homeostasis. During Zn limitation, Chlamydomonas reinhardtii hyperaccumulates Cu, a …

Acidocalcisomes are acidic organelles containing calcium and a high concentration of
phosphorus in the form of pyrophosphate (PPi) and polyphosphate (poly P). Organelles with …

Metal ion assimilation is essential for all forms of life. However, organisms must properly
control the availability of these nutrients within the cell to avoid inactivating proteins by …

We surveyed the iron nutrition-responsive transcriptome of Chlamydomonas reinhardtii
using RNA-Seq methodology. Presumed primary targets were identified in comparisons …

Acidocalcisomes are organelles conserved during evolution and closely related to the so-
called volutin granules of bacteria and archaea, to the acidocalcisome-like vacuoles of …

Diatoms, dinoflagellates, and coccolithophores are dominant groups of marine eukaryotic
phytoplankton that are collectively responsible for the majority of primary production in the …

Acidocalcisomes are organelles rich in polyphosphate and cations and acidified by proton
pumps. Although they have also been described in prokaryotes they have been better …
