external sensory organ precursor cell & dorsal mesothoracic disc, with Scer\GAL4sca-537.4
wing sensillum & wing vein, with Scer\GAL469B
wing sensillum & wing vein, with Scer\GAL4Bx-MS1096
Flies expressing BobAScer\UAS.cLa under the control of Scer\GAL4sca-537.4 show defects in the adult peripheral nervous system, having a strong tufting or lethal phenotype, with bristle tufting extending to most macrochaetae and microchaetae, as well as occasional bristle loss. Supernumerary sensory organ precursor cells are seen in wing imaginal discs of animals expressing BobAScer\UAS.cLa under the control of Scer\GAL4sca-537.4. Expression of BobAScer\UAS.cLa under the control of either Scer\GAL4Bx-MS1096 or Scer\GAL469B does not appear to alter wing vein fates or the overall integrity of the wing margin, although sensory organ fates in each of these territories are altered. Expression of BobAScer\UAS.cLa under the control of Scer\GAL4sca-109-68 occasionally results in a "double shaft" phenotype in which two bristle shafts are present at the expense of the socket cell.
The nucleotide sequence of the BobA clone used to make this construct has a one base conservative substitution difference from the nucleotide sequence of BobB and BobC. The predicted "Bob" protein produced by this construct is identical to that of BobA, BobB and BobC.
