Spatial expression and autoregulation of hetR, a gene involved in the control of heterocyst development in Anabaena
Abstract
Summary: The spatially patterned differentiation of hetero‐cysts in the filamentous cyanobacterium Anabaena requires a functional hetR gene. Transcriptional fusions to luxAB show that hetR is transcribed at a low level throughout the filament when Anabaena is grown with combined nitrogen, and that induction of the gene begins within 2 h following nitrogen deprivation. By 3.5 h, induction is localized to spaced foci. By 6h, there is an overall induction of at least threefold in whole cultures, reflecting at least a 20‐fold increase within spatially separated cells. The induction requires the presence of a functional hetR gene, indicating that hetR is autoregulatory. Full induction of a heterocyst structural gene, hepA, also requires a functional hetR locus.

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.
