mushroom body & axon, with Scer\GAL47B
mushroom body & axon, with Scer\GAL4c739
When expression is driven by Scer\GAL47B or Scer\GAL4c739, UY2635UY2635 shows a mushroom body Class III phenotype; axonal growth and guidance defects. The beta lobe axons do not stop at the interhemispheric boundary. The phenotype is more striking with Scer\GAL4c739 than with Scer\GAL47B or Scer\GAL4OK107.
