A Tag:FLAG tag has been inserted into the 3' end of P{UAS-ed.Δintra}.
edΔintra.Scer\UAS.T:Zzzz\FLAG twinspot clones generated in the dorsal compartment of larval wing discs expressing eddsRNA.Scer\UAS.intra under the control of Scer\GAL4ap-md544 are not surrounded by a prominent actomyosin cable. The clone cells do sort out to some degree from the ed deficient neighbouring cells, but as in wild type the clonal border is jagged. However, the clone cells do show strong apical constriction.
Expression of edΔintra.Scer\UAS.T:Zzzz\FLAG rescues the cell sorting phenotypes seen in larval wing disc clones expressing eddsRNA.Scer\UAS.intra. The surrounding wild type cells no longer assemble an actomyosin cable and the boundary between the clone and the surrounding wild type cells is no longer smooth edged, instead appearing jagged as in wild type.
