    Detailed Description

    Reference

    flamBG02658 homozygotes do not show significant mortality during the pharate stage.

    flamBG02658 heterozygote flies do not display any defects in the adult eye morphology.

    flamBG02658/flamKG00476 ovaries show defective germline and soma differentiation phenotypes. Somatic cells also die.

    Homozygous females do not lay any eggs.

    flamBG02658 flies have a permissive phenotype with respect to gypsy expression (assayed by expression of a P{gypsy-lacZ.p12} reporter construct in the ovaries).

    flamBG02658 flies are unstable for ZAM expression (assayed by expression of a P{ZAM-lacZ.LTR} reporter construct in the ovaries).

    24 hour old flamBG02658 females have ovaries which are very small and contain rudimentary ovarioles within which no differentiation of germ cells has taken place. Ovarioles of 48 hour old mutant females are severely dystrophic, containing two to three completely disorganised egg chambers which contain a reduced number of abnormally shaped nuclei. Mature eggs are rarely formed, and those that do are smaller than normal and appear to lack dorsal-ventral and anterior-posterior polarities. The dorsal appendages are short and abnormally shaped. The follicular epithelium is completely disorganised in the ovaries of 6-day old mutant females.

    Mosaic females containing homozygous germline clones develop several completely normal ovarioles and are fertile. The eggs produced by these females give rise to normal adult flies.

    flamBG02658, ctA double homozygotes present significant mortality during the pharate stage, as compared to controls.

    Xenogenetic Interactions
    Statement
    Reference

    The neurodegenerative rough eye phenotype characteristic for adult flies expressing Zzzz\CGG90.Scer\UAS.T:Avic\GFP-EGFP under the control of Scer\GAL4GMR.PU is exacerbated further by combination with a single copy of flamBG02658 (which is permissive for the gypsy retrotransposon expression).
