Detailed Description
| |||
Statement Reference Flies expressing Rho1[GMR.PH] have a rough eye phenotype associated with the frequent fusion of ommatidial units and misoriented or missing bristles. Rho1[GMR.PH] flies display a rough eye phenotype. Rho1GMR.PH flies have a rough eye phenotype. Flies expressing Rho1GMR.PH have a rough eye phenotype with a dramatic disruption of the ommatidial architecture. The retina is reduced in thickness and the lattices that are normally formed by the secondary and tertiary pigment cells are completely missing. Pigment cells are restricted to apical regions of the retina. Flies carrying two copies of the P{GMR-Rho1} insertion responsible for this allele, have an intermediate rough eye phenotype. Rough patterned eye with misshapen, fused and flattened ommatidia. Expression of Rho1GMR.PH in a wild-type background does not disrupt photoreceptor axon projections. Causes a rough eye phenotype. Pigment cells fail to extend to the retinal floor and the layer of pigment cell feet seen at the floor of the retina in wild-type animals is not seen in flies carrying one copy of Rho1GMR.PH. Flies carrying Rho1GMR.PH have rough eyes, with both the external and internal ordered structure of the eye being disrupted. The thickness of the retina is reduced. One copy of P{GMR-Rho1} allows normal external morphology, internal structure shows rhabdomeres are arranged in an irregular manner, but the eyes deform easily on application of mild pressure compared to wild type. Two copies, obtained by making the insertions homozygous, cause extremely rough eyes and flies carrying two copies, generated by crossing lines, have moderately rough eyes with a glassy appearance. Rough eye phenotype is due to a dramatic disruption of ommatidial architecture caused by disruption of cell differentiation. | |||

Additional Comments

Genetic Interactions

Statement Reference The rough-eye phenotype of Rho1[GMR.PH] flies is much reduced when Pax[GMR.PC] is co-expressed. The rough eye phenotype of Rho1GMR.PH flies is mildly enhanced by Mbs03802/+ (fewer bristles are formed). The Rho1GMR.PH phenotype is partially suppressed by ParpGMR.PU; ommatidial lattices are seen in the rescued flies and pigment cells are seen in deeper regions of the retina. A distinct rhabdomere structure also appears. Does not significantly alter the photoreceptor axon projection defects caused by expression of trioGEF1.GMR.T:Hsap\MYC. The rough eye phenotype caused by Rho1GMR.PH is suppressed by RhoGEF204291, RhoGEF21.1, RhoGEF22.3, RhoGEF22.6, RhoGEF22.9, RhoGEF24.1, RhoGEF24.4, RhoGEF25.1, RhoGEF25.2, RhoGEF26.5, RhoGEF28.1, RhoGEF28.9 and RhoGEF29.6. | |||
Xenogenetic Interactions
| |||
Statement Reference Co-expression of Zzzz\ExoS[GAP.Scer\UAS] under the control of Scer\GAL4[GMR.PF] restores the eye morphology to wild type in Rho1[GMR.PH] flies. The Hsap\RALAG23V.GMR eye phenotype is enhanced by Rho1GMR.PH; flies carrying one copy of either Hsap\RALAG23V.GMR or Rho1GMR.PH have a mild rough eye phenotype, while flies carrying both Hsap\RALAG23V.GMR and Rho1GMR.PH have extremely rough eyes with a glossy appearance due to the fusion of facets. A thin layer of pigment cells is seen in the apical region of the retina and no recognisable ommatidia can be seen. | |||
