Predominantly mutant Vha55j2E9 eye discs (generated using Scer\FLP1ey.PN) are small in size compared to wild type and have aberrant morphology.
Vha55j2E9 eye disc cells show an increased number of multivesicular bodies (MVBs) compared to wild type. These MVBs are enlarged and contain a high number of luminal vesicles.
A portion of the cells in Vha55j2E9 mosaic clones are eliminated from the disc, especially when surrounded by wild type cells.
Vha55j2E9 mosaic eye disc clones underproliferate compared to controls.
Mutants have clear Malpighian tubules (when examined by birefringence).
Homozygotes die around the time of hatching.
