lacZ expression is governed by 5.2kb from the upstream control region of Ubx, extending from the start of transcription in a 5' direction.
In embryos, similar to the basal Ubx pattern described in FBrf0047651. Only expression in the visceral mesoderm of parasegment 7 appears comparable to wild-type Ubx expression.
