Flies expressing ftScer\UAS.P\T.cSa under the control of Scer\GAL4αTub84B.PL have a normal overall pattern of polarisation in the eye, with only occasional incorrectly polarised ommatidia being seen. Expression of ftScer\UAS.P\T.cSa under the control of Scer\GAL4fj-VG1 has little effect on planar cell polarity in the eye. Expression of ftScer\UAS.P\T.cSa under the control of Scer\GAL4bi-omb3-GAL4 consistently leads to polarity reversals in the eye.
The polarity reversals in the eye seen in flies expressing ftScer\UAS.P\T.cSa under the control of Scer\GAL4bi-omb3-GAL4 is strengthened in a fjN7/fjd1 background.
