      Flies carrying one copy of Act88FD154N in a Act88F6/+ background are completely flightless.

      Flies carrying one copy of Act88FD154N in a Act88F6/+ background show major defects in Z-disc organisation in the indirect flight muscles. Recognisable ordered myofibrils are not formed in the indirect flight muscles of flies carrying two copies of Act88FD154N in a homozygous Act88F6 background, although disordered actin filaments are present.

      Closely packed Z-disc stacks or "zebra bodies" are seen in the indirect flight muscles of flies carrying one copy of Act88FD154N in a Act88F6/+ background.

      Ring-like Z-disc structures or aggregates and F-actin containing intranuclear rods are seen in the indirect flight muscles of flies carrying one copy of Act88FD154N in a Act88F6/+ background.

      Expression of Act88F+t4.0 in flies carrying one copy of Act88FD154N in a Act88F6/+ background largely partially flight ability. Normal myofibril structure in the indirect flight muscles is rescued.
