This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).
Breakpoint(s) molecularly mapped
Lethal in combination with Df(3L)GR844X22. Complements Df(3L)Δ26, Df(3L)Δ32, Df(3L)Δ54, Df(3L)Δ215, Df(3L)Δ3002, Df(3L)GR844X31 and Df(3L)GR844X33.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
The Df(3L)W4 chromosome does not act as a dominant suppressor of telomeric silencing (assayed using the effect of the chromosome on the eye colour phenotype of flies carrying "P{wvar}KR3-2", a stable "brown-red" variant of the P{3'WP-2,wvar}2Lt insertion).
Dominantly enhances the KrIf-1/+ eye phenotype.
Shows no maternal enhancement of dpphr4.
Midgut development of mutant embryos is wild type.
Homozygous embryos are very abnormal compared to wild-type.
Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.
Number of cells expressing midline glial cell markers in the embryonic CNS is increased by 60%.
Homozygotes show the full cell death defective phenotype.
75B puff is unchanged.
