A 38Kb deletion generated by 'FLPase' induced recombination between the insertions P{XP}d02180 and PBac{WH}CG42247f02655.
Stage 9/10 Df(3L)Brd-C1/Df(3R)E(spl)δ-6 transheterozygous embryos display loss of apical-basal cell polarity and of epithelial integrity; both these are rescued by sdtΔ3-GFP but not by sdtGFP3.
39% of embryos homozygous for the Df(3L)Brd-C1 and Df(3R)E(spl)δ-6 deletions and carrying one copy of Dp(3;2)E(spl)δ-8 fail to hatch and only 2% reach pupal stages.
DCX-EMAPtCa does not rescue the lethality of Df(3L)Brd-C1.
Animals homozygous for the Df(3L)Brd-C1 and Df(3R)E(spl)δ-6 deletions and carrying one copy of Dp(3;2)E(spl)δ-8Δα46 are 100% embryonic lethal.
The lethality of Df(3L)Brd-C1 is partially rescued by Dp(3;2)Brd-C; 20% of embryos develop into adult flies that are fertile.
60% of mutant animals die as embryos, and only 6% reach adulthood.
Homozygous clones in the notum do not perturb bristle development.
