Has no effect on mushroom body development when driven by Scer\GAL4c739.
When ttkp88.Scer\UAS is driven by Scer\GAL4Bx-MS1096 all dorsal chemosensory bristles are removed within the triple row, but the ventral chemosensory and medial mechanosensory bristles numbers are merely reduced. No effect is seen on wing blade area and cell proliferation.
The polar and equatorial cone cells are not present in any 12-cell stage ommatidia in eye discs expressing ttkp88.Scer\UAS under the control of Scer\GAL4hs.2sev (the four cone cells have normally been recruited by this stage in wild-type discs). Instead, R3 and R4 photoreceptor cells adopt an abnormally apical position within each ommatidium.
Scer\GAL4Kr.PM-mediated expression leads to a partial block of neuronal development in the PNS but no obvious defects in the CNS.
The external facet array is disorganised and all bristles are missing in the eyes of flies expressing ttkp88.Scer\UAS under the control of Scer\GAL4GMR.PF. No photoreceptors are seen and the remaining tissue is vacuolated. Lenses are present on the eye surface. The external facet array is moderately disrupted and some bristles are present in the eyes of flies expressing ttkp88.Scer\UAS under the control of Scer\GAL4hs.2sev. Ommatidia usually contain 4 outer photoreceptors and 1 central photoreceptor, which is an R8 cell.
