Description

EcoRI SalI fragment including the ABX control region of Ubx drives the expression of lacZ.

(Zhang et al., 1991)

lacZ reporter expression is governed by the Ubx proximal promoter (-3.1kb to +1kb) in combination with a SalI-EcoRI subfragment of the genomic 3136BR fragment.

Additional Information
Statement
Reference

The usual expression in ectodermal stripes of odd-numbered parasegments 5-13 is absent in eve3 mutant embryos.

(Muller and Bienz, 1992)

In embryos, no expression observed in mesoderm.

(Zhang et al., 1991)

n embryos, from stage 7, expressed in odd-numbered parasegments 5-13; expression highest in anterior portion of each parasegment, with a sharp border at the parasegment boundary.

(Muller and Bienz, 1991)
