Temperature sensitive. At 25C: Ste, during embryogenesis. Strong embryonic phenotype (anterior pharynx missing, no morophogenesis) if shifted during adulthood.

orEx2 [mlc-4p::mlc-4(genomic coding)::GFP::unc-54 3'UTR + rol-6(su1006)]. Maintain by picking Rollers. Rollers are GFP+.

Heterozygotes are WT and segregate WT, DpySteriles and late embryonic or early larval lethals with incomplete elongation/morphogenesis.

Homozygous or195 hermaphrodites make 100% dead embryos at 26C. One-cell embryo has a very small but bipolar spindle, severe chromosome segregation defect. Maintain at 15C. Previously called spd-4. 2/06: From Bruce Bowerman: The or195 mutation changes base 10,679 of the cosmid clone T21E12 from a C to a T. This corresponds to dhc-1 cDNA nucleotide 9599 (WS153) , which is the center nucleotide of codon 3200. This codon changes from Serine in N2 to Leucine in or195 (S3200L). Note: this is not the same mutation for or195ts that we reported in Hamill et al, 2002(Dev Cell 3, 673-684). The mutation reported in our paper is not present in this strain. We apologize for the confusion. The pairs dhc-11a,b amplify the mutated fragment in dhc-1(or195). The mutation is near the center of this fragment; a clean (gel purified) DNA prep helps get a good read of it. dhc-11b: 5' aacagacgcacgattgacct 3'. dhc-11a: 5' ctcaaatcaaggaaggagct 3'. PCR conditions: 5 min at 94 degrees C; 30 sec at 94 degrees C; 30 sec at 55 degrees C; 1 min at 72 degrees C. 35 Cycles using Taq polymerase.

Temperature sensitive spn-1. Maintain at 15C. Lethal at 25C. Heterozygotes are WT and segregate WT, Lon which give only dead eggs at all temperatures, and Sterile Dpys(ts).

Temperature-sensitive. Maintain at 15C. Reference: Gonczy P, et al. Dev Cell. 2001 Sep;1(3):363-75.

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.

Homozygous nearly sterile deletion chromosome balanced by bli-4- and GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ef15 homozygotes (pale, nearly sterile, lays few eggs). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: Schmid M, et al. Genes Dev. 2009 Apr 1;23(7):824-36.

[NOTE: (10/22/2020) This strain also carries a (T to A) missense mutation in pry-1 which results in a PRY-1 N354K amino acid substitution.] bar-1(ga80) hermaphrodites are usually Egl and often have a protruding vulva (Pvl), although approx. 40% of animals appear WT on plates. Also slightly Unc. In bar-1(ga80) hermaphrodites any of the six vulval precursor cells (P3.p - P8.p) can sometimes fuse with hyp7 without dividing, and P5.p - P7.p can adopt the tertiary cell fate instead of the primary or secondary fates. In addition, the neuroblast QL and its progeny migrate towards the anterior instead of the posterior, and the cell P12 usually adopts the fate of P11. bar-1(ga80) do mate, but poorly. bar-1 encodes a beta-catenin molecule and the ga80 mutation is predicted to cause an early truncation of the protein.
