Genetic mapping information

This deletion removes a single ribosomal protein-coding gene (though other genes are also removed).

Comments on Cytology

Pka-C3 gene lies within a 60kb region defined by the distal breakpoints of Df(3L)brm11 and Df(3L)st-f13.

    In combination with other aberrations

    Dominant scutellar bristle phenotype is increased in trans to Df(3L)A27 to around 48%.

    Df(3L)brm11/Df(3L)st-g24 lethal Df(3L)brm11/Df(3L)st-e4 viable Df(3L)brm11/Df(3L)st-b11 viable

    NOT in combination with other aberrations

    Flies heterozygous for the deletion do not show a Minute bristle phenotype.

    Df(3L)brm11 embryos show defects in tracheal cell migration.

    Heterozygotes show transformation of haltere to wing and of segment A5 to A4.

    The Df(3L)brm11 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).

    Shows dominant enhancement of dominant haltere phenotype caused by Ubx195 and Ubx9.22.

    Dominantly enhances the KrIf-1/+ eye phenotype.

    No second site non-complementing phenotype with zipEbr and zipmhc-c6.1.

    Midgut development of mutant embryos is wild type.

    Adults heterozygous for Df(3L)brm11 or Df(3L)th102 have a high frequency of duplications of the anterior scutellar bristles (around 24%).

    Dominant suppressor of Pc4.
