An inversion truncating the creA gene of Aspergillus nidulans results in carbon catabolite derepression

Mol Microbiol. 1990 May;4(5):851-4. doi: 10.1111/j.1365-2958.1990.tb00656.x.


The creAd-30 mutation leading to carbon catabolite derepression in Aspergillus nidulans is a pericentric inversion, having one breakpoint within the creA gene on the left arm of chromosome I and the other breakpoint between binG and yA on the right arm. The left-arm breakpoint alters the creA transcript. The likelihood that the inversion truncates creA centrally strengthens a previous proposal that derepression is the phenotype of loss-of-function mutations in creA.
