UASt sequences drive expression of Antp in which the linker domain (residues 288-295) and C-terminal domain have been replaced with those of Ubx isoform Ia (residues 244-284, and residues 346-380 respectively).
embryonic/first instar larval cuticle, with Scer\GAL4arm.PS
Keilin organ, with Scer\GAL4arm.PS
ventral denticle belt, with Scer\GAL4arm.PS
Embryonic/first instar larval cuticle phenotype due to Antp::UbxAAUA.Scer\UAS; Scer\GAL4arm.PS : 90% lack keilin's organs; denticle belt phenotype is mostly like that due to UbxIa.Scer\UAS; Scer\GAL4arm.PS.
