Description

lacZ reporter expression is driven by a fragment of the hb upstream region, that only carries the sequences for one high affinity bcd binding sites, and the hb transcription start site.

Additional Information
Statement
Reference

In early embryos, β-gal signal is very weak. At gastrulation, a weak stripe of expression observed in the head region; believed to be artifactual (see expression data for EcollacZC4.Adh, carried on the P{CaSpeR-AUG-βgal} construct).
