Mipp1KO/Mipp1KO embryos display tracheal phenotypes, with significantly elongated dorsal trunks and a significantly decreased percentage of dorsal branches fused with their contralateral partners. Mipp1KO/Mipp1KO embryos have a significantly reduced percentage of intercalated dorsal branches and number of filopodia per dorsal branch.
Mipp1KO has embryonic/larval tracheal dorsal trunk phenotype, enhanceable by Df(1)N73
Mipp1KO has embryonic/larval dorsal tracheal branch phenotype, enhanceable by Df(1)N73
Mipp1KO is rescued by Scer\GAL4btl.PS/Mipp1UAS.cCa
Mipp1KO is not rescued by Scer\GAL4btl.PS/Mipp1UAS.EGFP
Mipp1KO is not rescued by Mipp1H67A.UAS/Scer\GAL4btl.PS
Mipp1KO is not rescued by Scer\GAL4btl.PS/Mipp1ER.UAS
Reduced percentage of intercalated dorsal branches and decreased number of filopodia per dorsal branch in Mipp1KO/Mipp1KO embryos is rescued by Mipp1Scer\UAS.cCa (but not Mipp1H67A.Scer\UAS, Mipp1Scer\UAS.T:Avic\GFP-EGFP or Mipp1ER.Scer\UAS) expression in the trachea (using Scer\GAL4btl.PS driver).
