      Expression of shgdCR3h.Scer\UAS.T:Avic\GFP-rs in eyes, under the control of Scer\GAL4hs.2sev, causes under-rotation of ommatidia. Photoreceptor loss and patterning defects are minimal in these eyes and planar cell polarity defects are not observed. The ommatidial under-rotation is enhanced in flies with a shgk03401/+, shg1/+ or shg2/+ mutant background. The phenotype is suppressed in Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs; Scer\GAL4hs.2sev>shgScer\UAS.cSa flies.

      Coexpression of shgΔβ.Scer\UAS with shgdCR3h.Scer\UAS.T:Avic\GFP-rs, under the control of Scer\GAL4hs.2sev, does not rescue the shgdCR3h.Scer\UAS.T:Avic\GFP-rs ommatidial defects. Likewise, coexpression of shgex.Scer\UAS fails to rescue the ommatidial defects.

      The Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs eye phenotype is enhanced in a arm4 background, both in terms of the under-rotation of ommatidia and in defects associated with ommatidial architecture and adhesion, such as the appearance of gaps between the ommatidia. However, an arm2 background does not enhance the Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs eye phenotype; arm2 does not affect cell architecture in single mutants.

      The under-rotation of ommatidia seen in Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs eyes is enhanced by coexpression of CadNScer\UAS.cIa.

      Coexpression of Rho1dsRNA.Scer\UAS with shgdCR3h.Scer\UAS.T:Avic\GFP-rs, under the control of Scer\GAL4hs.2sev, enhances the under-rotation of ommatidia seen in Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs eyes. Similarly, expression of shgdCR3h.Scer\UAS.T:Avic\GFP-rs under the control of Scer\GAL4hs.2sev in a Rho172R/+ background, enhances the ommatidial rotation phenotype of shgdCR3h.Scer\UAS.T:Avic\GFP-rs flies.

      Neither a CadNM19/+ nor a Df(2L)CadNΔ14/+ background affects the Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs ommatidial phenotype. Likewise, the following genetic backgrounds do not affect the ommatidial phenotype: mys1/+, fz23/+, dsh1/+, stanE59/+, nmoP1/+, scaBP1/+ and rok2/+.

      Both a dgo380/+ and a Vangstbm-6/+ background enhances the ommatidial rotation phenotype of Scer\GAL4hs.2sev>shgdCR3h.Scer\UAS.T:Avic\GFP-rs eyes; a dgo380/+, Vangstbm-6/+ double mutant background further enhances this phenotype.

      Comments

      The addition of shgdCR3h.Scer\UAS.T:Avic\GFP-rs, driven by Scer\GAL4btl.PS, into shg2/Df(2R)E2 flies partially rescues their tracheal fusion phenotype producing incomplete dorsal trunk fusions.
