Trans regulation in the Ultrabithorax gene of Drosophila: alterations in the promoter enhance transvection.

The EMBO journal - 1 Oct 1992

Martínez-Laborda A, González-Reyes A, Morata G

Abstract excerpt

We report a genetic and molecular study of UbxMX6 and Ubx195rx1, two mutations in the Ultrabithorax (Ubx) locus which appear to have a strong effect on the activity of the homologous Ubx gene. These mutations show the characteristic embryonic and adult phenotypes of Ubx null alleles, and also fail to produce any detectable Ubx product. Yet, genetic and phenotypic analyses involving a large number of trans...
