Role of AbrB in Spo0A- and Spo0B-dependent utilization of a sporulation promoter in Bacillus subtilis
Open accessAbstract
Transcription of the Bacillus subtilis gene spoVG is induced at the onset of sporulation and is dependent on the products of the stage-0 regulatory genes spo0A, spo0B, and spo0H. We show here that the dependence of spoVG transcription on Spo0A and Spo0B (but not Spo0H) can be bypassed by a mutation at abrB, a previously identified locus at which mutations that suppress some of the phenotypes of spo0A are often located, or by a cis-acting mutation within the spoVG promoter. To explain the epistatis of abrB to spo0A and spo0B mutations, we propose that AbrB acts, directly or indirectly, to block transcription of spoVG and that Spo0A and Spo0B cause inactivation of the abrB gene product(s). Spo0A-Spo0B-dependent inactivation of AbrB could be a general explanation for the pleiotropic effects of spo0A and spo0B mutations on B. subtilis gene expression.

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.
