Clones of cells in the anterior compartment of the dorsal epidermis of the adult abdomen (in the tergite) that are co-expressing stanScer\UAS.cUa and fzScer\UAS.cUa under the control of Scer\GAL4αTub84B.PL in a stan- background (the cells within the clone are stanE59/stanE59 while the cells surrounding the clone are stan3/stanE59) do not change the cell polarity of the stan3/stanE59 cells surrounding the clone.
The reversal of cell polarity phenotype that is seen in cells posterior to clones in the anterior compartment of the dorsal epidermis of the adult abdomen (in the tergite) where the clones are expressing stanScer\UAS.cUa under the control of Scer\GAL4αTub84B.PL shows a longer range if the clones are induced in a dsunspecified background compared to a wild-type background.
The tissue polarity phenotype seen in the wings of flies expressing stanScer\UAS.cUa under the control of Scer\GAL4bi-md653 is blocked if the flies are simultaneously mutant for frtzunspecified, with the double mutant phenotype resembling that of frtzunspecified single mutants.
Cells within stanScer\UAS.cUa Scer\GAL4αTub84B.PL pwnunspecified/pwnunspecified clones (Scer\GAL80αTub84B.PL MARCM method) in the adult abdomen show some dishevelment. The clones induce extensive reversal behind the clone, both in the anterior and posterior compartments, and also within the clone, at the back. These clones do not cause planar repolarisation in a fz21/fz21 background.
The proportion of symmetrical (R3/R3) ommatidia in the eyes of stanScer\UAS.cUa; Scer\GAL4sev.PM181 flies is significantly enhanced by heterozygosity for DlRevF10 or dgo380, but is unaffected by heterozygosity for fz25, fz30, VangX, or Rho172O. The planar cell polarity phenotype displayed by the eyes of Nact.sev; stanScer\UAS.cUa ; Scer\GAL4sev.PM181 flies is distinct from that of stanScer\UAS.cUa ; Scer\GAL4sev.PM181 flies, but indistinguishable from that of Nact.sev flies.
The average area of the segmental nerve of stanE59/Df(2R)stan2 animals, in which stanScer\UAS.cUa is driven by Scer\GAL4elav-C155, is significantly larger than in wildtype controls or in the stanE59/Df(2R)stan2 mutants. A small number of axons (2-3 per segmental nerve) axons have large vacuoles.
