Description

Mutation of region 5 of module E of the Dfd response element (Dfd RE).

(Gross and McGinnis, 1996)

lacZ reporter expression is driven by 4 copies of a mutated module E of the Dfd epidermal autoregulatory element (Dfd EAE), a cluster of point mutations to increase sequence similarity to fragment H of Dhyd\Dfd, fused to an Hsp70 minimal promoter.

Additional Information
Statement
Reference

Novel expression is observed in a small dorsal patch near the anterior end of the embryo. Expression is also observed in the pharynx. Maxillary expression is nearly absent.
