The rough eye phenotype of phl::tor13D.hs.sev is enhanced by Src42A18-2, Src42A7-4, Df(2R)nap8, Df(2R)nap9 or In(2R)bwVDe2LCyR. The rough eye phenotype of phl::tor13D.hs.sev is not enhanced by Src42A1.15 or Src42A9-4. Lethality at the pupal stage is seen in Src42ASu(phl)1-1 phl::tor13D.hs.sev double heterozygotes.
When injected into the posterior of phl11 null embryos, phl::tor13D.hs.sev is highly efficient at rescuing posterior cuticular structures including A8 and the filzkorper. phl::tor13D.hs.sev is much less effective in rescuing Ras85DΔC40B null mutants though some rescue is seen at high concentrations of phl::tor13D.hs.sev. When injected into torrv66 at several concentrations generally around 5% of embryos were rescued.
