Detailed Description
|
|---|
| Expression of Hsap\SCA8CTG112.Scer\UAS under the control of Scer\GAL4GMR.PF results in disorganisation of the ommatidia and mechanosensory bristles of the eye, with the central portion of the eye being most severely affected. The penetrance of the phenotype is variable. The retina of 1- to 2-day old flies expressing Hsap\SCA8CTG112.Scer\UAS under the control of Scer\GAL4GMR.PF shows mild disorganisation with a loss of photoreceptor neurons and pigment cells. This retinal degeneration becomes progressively more severe as the flies age, with photoreceptor neurons becoming rod shaped and fragmented, resulting in vacuole formation. The recruitment and differentiation of photoreceptor neurons in larval eye discs expressing Hsap\SCA8CTG112.Scer\UAS under the control of Scer\GAL4GMR.PF appears to be normal, with degeneration of the photoreceptors appearing to begin during the pupal stages. |
