Detailed Description
Statement
Reference

No defects are seen in axon pruning during metamorphosis, though a severe proliferation defect is seen when somatic clones are made in the neuroblast.

Embryos transheterozygous for lwr05486 and lwr02858 show cuticle patterns resembling those of lwr118 homozygotes and of lwr05486/lwr118 transheterozygotes: a phenotype intermediate between the bcd and the hb mutant phenotypes. bcd protein is retained in the cytoplasm of lwr05486/lwr02858 transheterozygotes and lwr05486 homozygotes.

A loss of heterozygosity assay, using mwh1 as a marker, reveals that a lwr05486 heterozygous background increases the number of mwh1 clones after irradiation with 250 rad of X-rays, in p535A-1-4 mutants.

The rough eye phenotype found at 29[o]C in flies expressing p53Scer\UAS.Ex under the control of Scer\GAL4GMR.PF is not affected by a lwr05486 heterozygous background nor in a lwr05486-smt3k06307 transheterozygous background.

lwr05486/Df(2L)32FP-5 double heterozygotes show a reduction in wing size (by 10%) compared to wild type.

The transheterozygote lwr05486/smt304493 suppresses the mod(mdg4)ul suppression of the ct6 jagged wing phenotype, leading to a more jagged and discontinuous wing phenotype. The phenotype is also particularly pronounced in females, although it is detectable in both sexes.

The transheterozygote lwr05486/smt304493 suppresses the mod(mdg4)ul suppression of the y2 cuticle phenotype, leading to a lighter coloration of the abdomen (due to a reduction in y expression).These phenotypic changes occur in approximately 30% of the mutant flies, with the remaining 70% displaying a continuum of less-pronounced effect. The phenotype is also particularly pronounced in females, although it is detectable in both sexes.

lwr05486 dominantly suppresses the nondisjunction phenotype of nodDTW/+ females. noda/FM7a nod2 female nondisjunction is dominantly suppressed by lwr05486. 4th, but not X chromosome disjunction is suppressed in mei-2186 females if they also carry lwr05486/+. 4th, but not X chromosome disjunction is suppressed in AxsD females if they also carry lwr05486. ncd1/ncdD female X and 4th chromosome nondisjunction is dominantly suppressed by lwr05486. nodDTW mei-2181 double homozygous females show 60% X chromosome nondisjunction and 63% 4th chromosome nondisjunction. Oocyte spindles are often frayed or oddly shaped, or multiple spindles are present. These defects are suppressed by lwr05486/+.

A lwr05486 mutant background does not affect the extent of ectopic wing veins or eye roughening seen in Scer\GAL4GMR.PF CblDv.Scer\UAS mutants.

Excision of the P{PZ} element can revert the mutant phenotype.

Most excisions of the P{PZ} element are homozygous viable and no longer suppress nodDTW. Lethal excision alleles remain suppressors.
