The majority of embryos expressing stepScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 display either sporadic loss of cleavage furrow membranes or a general disruption to furrows across the embryo (involving both furrow loss and furrow disorganization).
55% of embryos derived from mothers expressing stepScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 have furrow canals of varying lengths. Most die as embryos.
stepUASp.EGFP/Scer\GAL4VP16.mat.αTub67C is a suppressor | maternal effect of furrow canal | maternal effect phenotype of Scer\GAL4VP16.mat.αTub67C, sstnRNAi.UASp.2
The expression of stepScer\UAS.P\T.T:Avic\GFP-EGFP under the control of Scer\GAL4prd.RG1 rescues the tissue distortions of stepKG09493/Df(2L)BSC150 mutant epidermis at germband retraction.
