    Detailed Description
    Statement
    Reference

    4.8% of segments have thin/missing commissures and 5.1% of segment have commissures with pathfinding errors in trioIMP159.4/trioM89 embryos.

    Heterozygotes with Df(3L)Fpa1 show mild irregularities in the commissures and longitudinal connectives of the embryonic central nervous system. Heterozygotes of trioS036810/trioM89 show a wing blister phenotype but are otherwise wild type.

    Statement
    Reference

    seq9.17 dominantly exacerbates the pre-pupal lethality of trioM89/trioS036810. However, survival to third instar larvae is indistinguishable between wild-type and the mutants. The seq9.17/+; trioM89/trioS036810 larvae retain the forager-like feeding behaviour at a time (90-93 hours after hatching) when their siblings and all control larvae have already transitioned to wanderers.

    Dominantly suppresses the S phase defects seen in the CycEJP eye disc.

    The suppression of prepupal lethality of trioM89/Df(3L)Fpa1 by enaGC10 is incomplete. Lethality is delayed until pupariation, but adults are never recovered.
