StuA is required for cell pattern formation in Aspergillus.
Open accessAbstract
The stunted (stuA) gene product is required for the orderly differentiation and spatial organization of cell types of the Aspergillus nidulans conidiophore. Expression of the stuA gene is complex. Two transcripts, stuA alpha and stuA beta, are initiated from separate promoters. Transcription of both RNAs increases approximately 50-fold during the establishment of developmental competence. Induction-dependent transcriptional and post-transcriptional regulatory mechanisms further enhance expression 15-fold. Consistent with the latter observation, both transcripts have structural features characteristic of RNAs subject to translational control. Conidiophore morphogenesis requires regulatory interactions between the products of the stuA, bristle (brlA), and abacus (abaA) genes. Enhanced stunted expression is cell type specific and dependent on a functional BrlA protein. StuA affects the spatial localization of AbaA by acting directly, or indirectly, to repress abaA 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.
