Expression of ttkp88.Scer\UAS under the control of Scer\GAL4twi.PB and Scer\GAL4how-24B does not lead to an obvious adult phenotype, as compared to controls.

Scer\GAL4hs.2sev-mediated expression of ttkp88.Scer\UAS induces the loss of at least one cone cell in about 90% of the ommatidia.

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.

Expression of ttkp88.Scer\UAS under the control of Scer\GAL4GMR.PF does not abolish the second mitotic wave in the eye disc.

Flies expressing ttkp88.Scer\UAS under the control of Scer\GAL4cb19 are moderately viable.

Expression of ttkp88.Scer\UAS under the control of Scer\GAL4dpp.blk1 has no effect on furrow initiation in the eye disc.

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.

Reference

ttkp88.Scer\UAS Scer\GAL4hs.2sev, svsev.PS pupal eye discs have additional cone cells in about 40% of their ommatidia , with a maximum of seven cone cells observed in 1% of the ommatidia.

One supernumerary cone cell is generated in most ttkp88.Scer\UAS Scer\GAL4hs.2sev, svsev.PS ommatidia, while up to three additional cone cells are generated in only 4% of the ommatidia.

Comments

ttkp88.Scer\UAS (driven by Scer\GAL4hs.PB fails to rescue the chorion and dorsal appendage phenotypes of ttktwp/ttk1e11 eggs under any heat shock conditions.
