Genetic mapping information
Comments

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

(Marygold et al., 2007)

Homozygous deficiency embryos show six instead of seven ftz protein stripes (Mahoney and Lengyel, 1987)

    In combination with other aberrations

    NOT in combination with other aberrations

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

    (Marygold et al., 2007)

    Does not give a Minute phenotype when heterozygous.

    (Cook, 2006.1.31)

    During cellularization of Df(3R)tll-e embryos (which are deficient for bnk), actin rings constrict prematurely, pinching the nuclei and causing the 'bottleneck' phenotype.

    (Padash Barmchi et al., 2005)

    During cellularization in Df(3R)tll-e homozygous embryos, the microfilament rings at the base of the furrow canals constrict prematurely. The rings squeeze the nuclei into dumbbell shapes during early cellularization, trapping and dragging some of them along with the advancing cellularization front during late cellularization.

    (Thomas and Wieschaus, 2004)

    Lack hindgut, Malpighian tubules and much of the posterior midgut.

    (Pignoni et al., 1990)

    Individuals have an abnormal dorsal cephalopharyngeal apparatus.

    Other Comments
     

    The Df(3R)tll-e chromosome may 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), but the eye colour phenotype in the presence of Df(3R)tll-e overlaps the eye colour phenotype in a wild-type background so it cannot be unequivocally demonstrated that the deficiency chromosome uncovers a suppressor of telomeric silencing.
