Direct control of antennal identity by the spineless-aristapedia gene of Drosophila.

Abstract excerpt

Loss-of-function mutations in the spineless-aristapedia gene of Drosophila (ssa mutants) cause transformations of the distal antenna to distal second leg, deletions or fusions of the tarsi from all three legs, a general reduction in bristle size, and sterility. Because ssa mutants are pleiotropic, it has been suggested that ss+ has some rather general function and that the ssa antennal transformation is an...
