Fig. 1. Inducing high levels of Ubx eliminates Ubx protein in the haltere disc. Discs are oriented with the anterior compartment towards the left and the ventral compartment upwards. (A) Haltere imaginal disc of a Ubxlac1/TM6B stock, showing lacZ expression in the disc. (B) In a C765-Gal4/UAS-Ubx Ubxlac1 haltere disc, lacZ expression is almost abolished and the size of the haltere is reduced. (C) Wild-type haltere. (D,E) Halteres of E132-Gal4/UAS-Ubx (D) and MS372-Gal4/UAS-Ubx (E) flies. Note the increased size, with respect to C, and the appearance of wing bristles and thricomes. (F) In a MS372-Gal4/UAS-Ubx haltere disc, there are patches lacking Ubx protein expression.
