CHLAMYDOMONAS EUGAMETOS (CHLOROPHYTA) STORES PHOSPHATE IN POLYPHOSPHATE BODIES TOGETHER WITH CALCIUM1
Open accessAbstract
When Chlamydomonas eugametos Moewus cells are starved of phosphate, they accumulate 32 P i much faster than before starvation. Phosphate accumulation is stimulated by calcium. Less than 5% of the 32 P i taken up by the cell is present in soluble molecules, suggesting that most is in a metabolically inactive, storage form. Nuclear magnetic resonance and X‐ray microanalysis data are presented to show that it is stored as polyphosphate in electron‐dense bodies hi the cytoplasm. The same bodies accumulate divalent cations, in particular calcium. The P/Ca ratio in the bodies was maintained between 5.4 (1‐week‐old cells) and 3.3 (5‐week‐old cells) during cultivation, suggesting that the calcium and phosphorus relations of the bodies are coupled. The possibility that these electron‐dense bodies represent calcium stores that can be released to activate calcium signaling is discussed.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
