Rab11ex1 heterozygous flies show no significant border cell migration defects.
Rab11ex1/+ flies show no eye phenotype.
Rab11ex1/Rab1193Bi transheterozygotes are mostly lethal but a few survive to adulthood.
The posterior abdomens of Rab11ex1/Rab1193Bi flies have empty sockets that are missing microchaetae. Additionally, posterior scutellar bristles are shortened in these mutants.
The synapse of muscle 6/7 shows an increase in boutons by about 60% in Rab11ex1/Rab1193Bi mutants compared to controls. The boutons of Rab11ex1/Rab1193Bi mutants are often clustered resulting in a 'bunch of grapes' morphology instead of the wild-type 'beads-on-a-string' morphology. The aberrant morphology may reflect increased branching (by 2.6 fold) of Rab11ex1/Rab1193Bi boutons.
Oogenesis is arrested before oocyte determination in Rab11ex1 germ-line clones.

Rab11[+]/Rab11ex1 is an enhancer of eye phenotype of Scer\GAL4GMR.PF, bchsEP2299
A Rab11ex1 heterozygous background enhances the restriction on border cell migration seen upon expression of Evi5Scer\UAS.T:Disc\RFP-mCherry in border cells under the control of Scer\GAL4c306. The number of clusters unable to initiate migration is strongly increased.
Rab11ex1 heterozygotes act as dominant enhancers of the Scer\GAL4GMR.PF>bchsEP2299 eye phenotype, resulting in adults with severely reduced eyes.
The viability of Rab11ex1/Rab1193Bi is increased when flies are also mutant for either Df(2L)cl7/+, Df(2L)cl7/bchs17, bchs17/bchs12 or bchs17/+.
The microchaeta loss of Rab11ex1/Rab1193Bi flies is significantly suppressed by Df(2L)cl7/+ or bchs17/+ and is completely suppressed by Df(2L)cl7/bchs17 or bchs17/bchs12. Further, posterior scutellar bristle length of Rab11ex1/Rab1193Bi flies is restored partially by Df(2L)cl7/+ or bchs17/+ and more fully by Df(2L)cl7/bchs17 or bchs17/bchs12.
The bouton density and branching defects of Rab11ex1/Rab1193Bi larval NMJs at muscle 6/7 are significantly suppressed in bchs17/bchs12; Rab11ex1/Rab1193Bi double mutants.
