    nucleus & oocyte | germ-line clone

    Detailed Description
    Statement
    Reference

    Fully mutant germ-line clones cannot be made. However mosaic oocytes are seen. In these cysts, the mutant cells show an aberrant organisation of the actin cytoskeleton, nuclei of reduced size, and a detachment of the follicle cells (which is indicative of cell death).

    Additional Comments
    Genetic Interactions
    Statement
    Reference

    eIF4AIII19 dominantly suppresses the rough eye phenotype caused by Ras85DV12.sev.

    The osk and stau localisation phenotypes seen in btz1 oocytes are enhanced in combination with eIF4AIII19. The loss of pole cells and the associated loss of ovaries is also enhanced: penetrance of this phenotype increases from 6% to 31%, for loss of at least one ovary. Embryos produced by btz1 females with one copy of osk2 show a partial loss of abdominal segments. This phenotype is enhanced by the presence of eIF4AIII19.
