title: TheUbx syndrome ofDrosophila: the prothoracic transformation (ppx) is independent ofbx, bxd andpbx.
abstract: If, early in development, theUbx+gene is removed by mitotic recombination from cells of the meso-and metathoracic leg primordia, theseUbx-cells develop as in the posterior prothoracic leg. We show that this transformation, termedpostprothorax, is a discrete genetic function that is independent of other homeotic transformations such asbx, pbx orbxd, which also result from the inactivation of theUbx gene.
