      Expressing forUAS.T1 under the control of Scer\GAL4for.pr1 (but not Scer\GAL4for.pr2, Scer\GAL4for.pr3 or Scer\GAL4for.pr4) in a for0/for0 background results in a longer travel path during feeding in third instar larvae compared to for0/for0 controls, while expression under the control of Scer\GAL4for.pr4 (but not Scer\GAL4for.pr1, Scer\GAL4for.pr2 or Scer\GAL4for.pr3) in a for0/for0 background increases food intake in larvae compared to for0/for0 controls.

      (Allen et al., 2018)

      for0 homozygotes die in late pupal stage.

      The for0;for+tBAC rescue larvae as well as fors;for+tBAC larvae show increased travel path length during feeding and higher food intake compared to for0 homozygotes. Dp(2;2)for-dup mutant larvae also show significantly increased path length as well as higher food consumption relative to for0. for0/forR transheterozygotes display longer travel path and reduced food intake compared to for0/fors.

      Comments

      None of the following deletions Df(2L)drm-P2, Df(2L)ED243 and Df(2L)Exel7018 can be complemented by for0.

      The late pupal lethality of for0 homozygotes is rescued by combination with a single copy of for+tBAC.
