UAS sequences drive expression of Ubx isoform Ia lacking the C-terminal 35 residues (346-380).
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 UbxIa.UUU.Scer\UAS; Scer\GAL4arm.PS : 80% lack Keilin's organs; denticle phenotypes are mostly like those due to UbxIa.Scer\UAS; Scer\GAL4arm.PS.
