Expression of eyaScer\UAS.cPa under the control of Scer\GAL430A does not result in the induction of ectopic retinal cells in the wing disc.

Ectopic expression of eyaScer\UAS.cPa using Scer\GAL4dpp.blk1 produces very small ectopic eyes on the head ventral to the antennae in 34% of flies. A tiny spot of red pigment is seen at the joint between the coxa and femur of the leg in 95% of cases, and on the wing blade in 26% of cases.

Ectopic expression of eyaScer\UAS.cPa under the control of Scer\GAL4dpp.blk1 often causes mild growth alterations in the antennal disc, resulting in extra folds in the epithelium and, rarely, formation of small ectopic ommatidial arrays. Very small patches of red pigment cells are often induced on the antennae, wings and legs in these flies.

When both dacScer\UAS.T:Ivir\HA1 and eyaScer\UAS.cPa are driven by Scer\GAL4dpp.blk1, they act synergistically on the ectopic eye phenotype to form large patches of ectopic eye tissue ventral to the antenna that often fuse and expands the wild-type eye. Ectopic eyes are also seen on the leg and thorax. When both dacΔN.Scer\UAS.T:Ivir\HA1, dacΔN.Scer\UAS.T:Ivir\HA1, dacΔNLS2.Scer\UAS.T:Ivir\HA1, dacΔM.Scer\UAS.T:Ivir\HA1, dacΔC.Scer\UAS.T:Ivir\HA1, dacN.DD1.DD2.Scer\UAS.T:Ivir\HA1, or dacN.DD1.M.Scer\UAS.T:Ivir\HA1 and eyaScer\UAS.cPa are driven by Scer\GAL4dpp.blk1, they act synergistically on the ectopic eye phenotype. Larger and more penetrant ectopic eye formation is seen ventral to the antenna. When both dacΔDD1.Scer\UAS.T:Ivir\HA1 and eyaScer\UAS.cPa are driven by Scer\GAL4dpp.blk1, they act synergistically on the ectopic eye phenotype. Red pigmentation is seen on the dorsolateral side of the antenna with no ommatidia is seen. When both dacN.DD2.Scer\UAS.T:Ivir\HA1, dacΔDD1.ΔDD2.Scer\UAS.T:Ivir\HA1, or dacN.DD1.Scer\UAS.T:Ivir\HA1and eyaScer\UAS.cPa are driven by Scer\GAL4dpp.blk1, no enhancement of the ectopic eye phenotype is seen.

Clones of soScer\UAS.cPa; eyaScer\UAS.cPa; Scer\GAL4Act5C.PP cells in the testes do not induce precocious spermatocyte development.

When dppScer\UAS.cSa, eyaScer\UAS.cPa and eyScer\UAS.cHa are driven by Scer\GAL430A, photoreceptor differentiation is induced in both compartments of the wing disc. The addition of soScer\UAS.cPa increases the penetrance of this phenotype. When hhScer\UAS.cCa, eyaScer\UAS.cPa and eyScer\UAS.cHa are driven by Scer\GAL430A, photoreceptor differentiation is induced in the wing disc, only in the posterior compartment. The addition of dppScer\UAS.cSa or eyaScer\UAS.cPa (driven by Scer\GAL4ey.PB) to animals with smoD16 clones in the eye disc has no effect on the photoreceptor differentiation phenotype seen in eye discs. The delayed progression of the morphogenetic furrow is also not affected. The addition of soScer\UAS.cPa and eyaScer\UAS.cPa (driven by Scer\GAL4ey.PB) to animals with smoD16 clones in the eye disc has no effect on the photoreceptor differentiation phenotype seen in eye discs. The delayed progression of the morphogenetic furrow is also not affected. The addition of dppScer\UAS.cSa and eyaScer\UAS.cPa (driven by Scer\GAL4ey.PB) to animals with smoD16 clones in the eye disc, fully suppresses photoreceptor differentiation phenotype seen in eye discs. The delayed progression of the morphogenetic furrow is also rescued.

Enhances the ectopic retinal development phenotype in the wing disc caused by expression of eyScer\UAS.cHa under the control of Scer\GAL430A.

Coexpression of eyaScer\UAS.cPa and dacScer\UAS.cSa using Scer\GAL4dpp.blk1 induces substantial ectopic eyes on the head, legs, wings and dorsal thorax. The cuticle between the normal eye field and the antenna is transformed into retinal cells such that the normal retinal field is expanded. Large patches of pigment are induced on the dorsal side of the femur and tibia of all legs, which are severely truncated. Ommatidial structures are observed in these patches. Red pigment, but no clear ommatidial morphology, is induced on the wing blade. Ectopic eyes are induced bilaterally on the dorsal thorax. All these phenotypes have 100% penetrance. Coexpression of eyaScer\UAS.cPa and dacScer\UAS.cSa using Scer\GAL4dpp.blk1 induces ectopic morphogenetic furrow advancement from the ventral side of the eye in late larval eye-antennal discs. Substantial ectopic photoreceptor development is also seen. The axons of these ectopic photoreceptors form a bundle that extends posteriorly into the eye imaginal disc. These axons appear to fuse with the axon tracts sent out by photoreceptors of the normal retinal field and probably exit through the optic stalk and synapse with the larval brain. Ectopic neurons are induced in leg and wing discs. Axons extended by these neurons retract during late larval and pupal development.

Coexpression of both eyaScer\UAS.cPa and soScer\UAS.cPa under the control of Scer\GAL4dpp.blk1 results in a dramatic increase in the development of eye tissue in antennal discs compared to expression of eyaScer\UAS.cPa alone under the control of Scer\GAL4dpp.blk1. This tissue develops into adult eye structures. There is also an increase in the frequency and size of red pigmented patches on the wings and legs. Ectopic eyes are not produced when eyaScer\UAS.cPa and soScer\UAS.cPa are coexpressed under the control of Scer\GAL4dpp.blk1 in an ey2 background, although growth alterations and patches of red pigment cells on the legs are still seen.

Comments

The lack of Bolwig's organ neurons seen in eyacli-IID embryos is partially rescued by eyaScer\UAS.cPa expressed under the control of Scer\GAL4h-1J3.
