Expression of Rho11.dsRNA.Scer\UAS throughout the pupal eye, beginning at puparium formation (0h APF), under the control of Scer\GAL4GMR.PF results in severe disruption of the adherens junctions. Only the adherens junctions between the pigment epithelial cells (PECs) are affected, with those between a PEC and a cone cell or between cone cells appearing normal.

Depleting Rho1 in a single pigment epithelial cell through expression of Rho11.dsRNA.Scer\UAS using the flippase-out technique (under the control of Scer\GAL4Act5C.PI) does not affect the adherens junctions or the polarised localisation of shg but does result in an enlarged apical cell area. However, in multiple-cell Rho11.dsRNA.Scer\UAS clones, adherens junctions are disrupted but only between adjacent clonal cells and not between wild-type and clonal cells. An enlarged apical area is present in all Rho11.dsRNA.Scer\UAS-depleted clones regardless of the Rho1 status of neighboring cells.

Depletion of Rho1 in the pupal wing through expression of Rho11.dsRNA.Scer\UAS using the flippase-out technique (under the control of Scer\GAL4Act5C.PI) results in increased apical cell areas and disruption of adherens junctions but not septate junctions.

Statement
Reference

The dot-like small eye phenotype characteristic for flies expressing egrScer\UAS.cMa under the control of Scer\GAL4GMR.PFa is exacerbated further by co-expression of Rho1dsRNA.1.Scer\UAS RNAi resulting in a 'no eye' phenotype with scar-like and necrosis-like tissue present.

Clones expressing Rho11.dsRNA.Scer\UAS and overexpressing shgScer\UAS.cSa exhibit disrupted adherens junctions.

Expression of Rho11.dsRNA.Scer\UAS under the control of Scer\GAL4Act5C.PI does not affect the adherens junctions between Cdc424 mutant cells.

Expression of Rho11.dsRNA.Scer\UAS under the control of Scer\GAL4Act5C.PI does not affect the adherens junctions between par-6Δ226 mutant cells.
