UASt regulatory sequences drive expression of a full-length Bmor\tal-like cDNA.
Expression of Bmor\tal-likeScer\UAS.cGa in the dorsal leg, under the control of Scer\GAL4dpp.blk1, produces transformation of the distal tibia and fusion to tarsus 1, and ectopic sex combs in tarsi 1 and 2. These phenotypes are compatible with a transformation of tibial identity towards tarsus.
Ectopic expression of Bmor\tal-likeScer\UAS.cGa in the embryonic head, under the control of Scer\GAL4Dll-md23 produces extra sclerotised elements in the cephalopharyngeal skeleton.
Expression of Bmor\tal-likeScer\UAS.cGa under the control of Scer\GAL4unspecified rescues the talunspecified phenotypes in the adult and the embryo.
