Df(3L)lxd6/Df(3L)vin4 transheterozygotes show the same head involution defects as Df(3L)vin4 homozygotes.
Complements Df(3L)TP32.
Flies heterozygous for the deletion do not show a Minute bristle phenotype.
Df(3L)vin4 mutants show defects in head involution. The mouth hooks are present but the labrum and epistomal sclerites are missing and at least part of the cephalopharyngeal skeleton remains at the surface of the embryo.
Df(3L)vin4 embryos show reduced levels of cell death, as evidenced by lower levels of Decay protein activity.
Homozygous embryos have abnormal gut morphology.
Homozygous embryos have reduced anal pads. Midgut constrictions do not form, the hindgut is shorter than normal and Malpighian tubules form short buds.
Heterozygosity for this deletion suppresses the mutant ovarian phenotype of ovoD2.
Transheterozygote Df(3L)vin4 Df(3L)vin6 embryos (null for byn) have a major part of the hindgut missing after germ band extension. proctodeum develops aberrantly after germ band extension. Anal pads are also not formed.
Fertile when heterozygous with haync2.
