Interaction between spineless-aristapedia gene and genes from Antennapedia and bithorax complexes of Drosophila melanogaster.

Abstract excerpt

Mutations in the spineless-aristapedia (ssa) gene of Drosophila melanogaster are pleiotropic, and their classical manifestations include a reduction in size of all bristles (spineless phenotype), transformation of distal parts of antennae into tarsal segments of the mesothoracic leg (aristapedia phenotype), and, in extreme alleles, fusion of tarsal segments on all six legs and the transformed aristaes.
