knirps and knirps-related are sufficient for dorsal-branch migration. btl95 mutant embryos (A) show defects in DB (arrows) and Lta migration (arrowheads). Expression of wild-type btl in btl95 embryos (B) rescues the DB (arrows) and Lta (arrowheads) migration defects. Both the DB (arrows) and Lta (arrowheads) fail to migrate in btl95 embryos expressing wild-type tkv (C). In btl95 embryos expressing either activated tkv (D), wild-type knrl (E), or wild-type kni (F), the DBs (arrows) migrate normally, although the Lta (arrowheads) still fail to migrate. All embryos shown are at stage 14 and were stained for Crumbs and β-gal.
