The cleft thorax phenotype of flies that express either Mnn1Scer\UAS.cCa or JrabZIP.Scer\UAS under the control of Scer\GAL4pnr-MD237 is enhanced when Mnn1Scer\UAS.cCa and JrabZIP.Scer\UAS are expressed together by Scer\GAL4pnr-MD237. Further, flies that coexpress Mnn1Scer\UAS.cCa and JrabZIP.Scer\UAS under the control of Scer\GAL4how-24B are lethal at pupal stage P7, which is earlier than the pharate adult lethality of Scer\GAL4how-24B>Mnn1Scer\UAS.cCa flies.
Coexpression of Mnn1Scer\UAS.cCa and JraAsp.B.Scer\UAS under the control of Scer\GAL4pnr-MD237 results in 1-5% of flies escaping the JraAsp.B.Scer\UAS lethality to eclose. Viable flies have a severe cleft thorax. Likewise, the prepupal lethality of Scer\GAL4ey.PH>JraAsp.B.Scer\UAS flies is partially suppressed when Mnn1Scer\UAS.cCa is coexpressed.
Coexpression of Mnn1Scer\UAS.cCa and JraScer\UAS.cEa under the control of either Scer\GAL4pnr-MD237, Scer\GAL4ey.PH or Scer\GAL4how-24B results in the same phenotypes as expression of Mnn1Scer\UAS.cCa alone.
