Fig. 11. — Expression of pnt suppresses the formation of the antenna that results from Toy/ISWI knockdown. (A) The formation of the second antenna (induced from knocking down Toy/ISWI) is completely suppressed by the expression of pnt. The locus encodes two isoforms, PntP1 and PntP2. (D) The formation of the second antenna [induced from knocking down Toy and E(bx)] is completely suppressed by the expression of pnt. (B,E) Expression of the PntP1 isoform alone using the UAS/GAL4 system suppresses ectopic antenna formation. Note that eye development is severely impaired by the ectopic expression of PntP1. (C,F) In contrast, the expression of PntP2 fails to suppress the formation of the second antenna. Scale bar: 50 µm.
