Figure 3. Cross-regulation between Ubx and abd-A.

Figure 3

Lateral views of stage 11 Drosophila embryos immunostained for Ubx (green) and Abd-A (red). A. Pattern of Ubx expression in wild type (left) and abd-A− embryos. Note that Ubx is de-repressed in abd-A mutants. B. abd-A expression is the same in wild type (left) and Ubx mutant (right) embryos. C. PrdG4;UAS-Ubx embryo showing that ectopic Ubx represses abd-A. D. PrdG4;UAS-Abd-A embryo showing that ectopic Abd-A represses Ubx.
