    Reference

    P{lacW}moiS096713/Df(3R)d189 animals carrying P{CaSpeR-DTLum} (i.e. moi mutants) eclose and survive for a short time, exhibiting signs of locomotor defects, rough eyes, missing wing veins, scalloped wings and missing thoracic bristles.

    Mitotic cells from the brains of moi1/moiS096713 and and moiS096713/moiCB02140 larvae show frequent telomere fusions.

    Flies homozygous for the P{lacW}moiS096713 insertion die as third instar larvae.

    Homozygotes die as third instar larvae.

    tefuatm-6 flies that also carry P{lacW}moiS096713/Df(3R)d189, P{CaSpeR-DTLum} (i.e. moi mutants) die at an earlier phase than either single mutant condition.

    tefuatm-6 neuroblasts that also carry P{lacW}moiS096713/Df(3R)d189, P{CaSpeR-DTLum} (i.e. moi mutants) show an increased number of anaphase chromosome bridges than either single mutant condition.

    P{lacW}moiS096713/Df(3R)d189, P{CaSpeR-DTLum} (i.e. moi mutant) neuroblasts show fewer anaphase chromosome bridges when mei-41RT1 is present.

    P{CaSpeR-DTL} (expressing wild type moi and Tgs1) rescues the lethality of P{lacW}moiS096713/Df(3R)d189.

    The presence of P{CaSpeR-DTLdm} (expressing wild type moi) does not change the lethality phase of P{lacW}moiS096713/Df(3R)d189.

    The P3-P4 early pupal lethality seen in P{lacW}moiS096713/Df(3R)d189 animals is completely rescued by P{CaSpeR-DTL} (which carries moi+t4.6 and tatl+t4.6).

    The P3-P4 early pupal lethality seen in P{lacW}moiS096713/Df(3R)d189 animals is not rescued by P{CaSpeR-DTLdm} (which carries tatldm.t4.6 and moidm.t4.6).

    The P3-P4 early pupal lethality seen in P{lacW}moiS096713/Df(3R)d189 animals is partially rescued by P{CaSpeR-DTLum} (which carries tatlum.t4.6 and moium.t4.6); animals die as pharate adults or immediately after hatching.

    The P3-P4 early pupal lethality seen in P{lacW}moiS096713/Df(3R)d189 animals is completely rescued by P{CaSpeR-DTLdm} and P{CaSpeR-DTLum} together in trans.

    Associated with: tatlS096713.

    The P{lacW}moiS096713 insertion maps upstream of a dicistronic locus that encodes moi (upstream ORF) and tatl (downstream ORF). Rescue analysis indicates that the telomere fusion phenotype seen in P{lacW}moiS096713 mutants is due to an effect on the moi ORF and not on tatl. In contrast, the lethality caused by the insertion is not rescued by a transgene containing either ORF alone, but is rescued by a transgene containing functional copies of both ORFs, indicating that the lethality is due to an effect on both ORFs.

    Allelic series (with respect to severity of telomere fusion phenotype): moi1 > moiCB02140 = moiM12 > moiS096713.
