Temperature-sensitive, embryonic-lethal mutant that lacks a central spindle during early embryonic mitosis and exhibits a late cytokinesis defect (cleavage furrows regress after ingressing in nearly to the center of dividing embryonic cells). About 100% of embryos produced by homozygous mothers hatch at 15C; 0% hatch at 26C. ZEN-4 = vertebrate MKLP1 kinesin. There are two mis-sense mutations present in zen-4(or153). One is a D520N (GAC to AAC) and the other is D735N (GAT to AAT). Whether one or both is responsible for the phenotype is not know. Maintain at 15C. Shift L4s to 26 overnight to observe mutant phenotype on embyros produced by adults.

Temperature-sensitive embryonic lethal. Maintain at 15C. Reference: O'Rourke SM, et al. PLoS One. 2011 Mar 1;6(3):e16644.

Temperature sensitive. Viable at 15C; lethal at 25C. At 25C, embryos exhibit defects in spindle orientation and cell fate patterning.

Maintain at 15C. Temperature-sensitive embryonic-lethal at restrictive temperature of 26C. Viable embryos at permissive temperature of 15C. Mitotic spindle in one-cell stage embryo assembles normally, but microtubules destabilize at anaphase and spindle becomes mis-positioned toward the posterior pole leading to highly abnormal cleavage and chromosome segregation defects.

Heterozygotes segregate wild-type heterozygotes, Dpy, and sec-5 homozygotes (scrawny, small broods, abnormal gut appearance) sec-5 is homozygous maternal-effect lethal; M+Z- animals produce a few dead L1-L2 stage larvae with Vab defects. Based upon phenotype, pk2357 is a strong loss-of-function, but likely not a null allele; molecular lesion produces a premature stop at position 389. Reference: Frische EW, et al. EMBO J. 2007 Dec 12;26(24):5083-92. [NOTE: This strain was previously described as carrying pk2358, but pk2357 is the correct allele. Both pk2357 and pk2358 cause the same nonsense (amber) change.]
