The effect of ecdysterone on the cyanobacterium Nostoc 6720
Open accessAbstract
The insect hormone ecdysterone stimulated dinitrogen fixation, heterocyst formation, cell size and protein synthesis in suspension cultures of the cyanobacterium Nostoc 6720 within 48 h when added to the culture at concentrations between 10-9 and 10-7 м. In the presence of the hormone the volume of vegetative cells increased by 6-fold and that of heterocysts by nearly twice as compared to untreated controls. All the observed effects were inhibited by the calcium- calmodulin inhibitor, trifluoperazine. Cholesterol used as a null control had no significant effect.

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.
