Strain Genotype Description
BS5431 prp-17(oz273) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). Homozygous sterile mutation 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 sterile oz273 homozygotes. Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain.
BS5435 prp-17(oz273) I/hT2 (I;III); glp-1(oz264) III/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). glp-1(oz264) is a gain-of-function allele. Homozygous sterile mutation 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 sterile oz273; oz264 homozygotes. Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain.

BW54 ct350 II. Maintain at 15C. Temperature sensitive embryonic lethal. Sterile at 25C. Congenic strain, N2 and Bergerac BE. This allele should NOT be assumed to define a gene to which someone gave the name zyg-12. This name should not be used unless someone finds a non-complementing Bristol mutation. There is no evidence at present that the ts results from a single gene defect. Has been backcrossed >6 times to Bristol strains and should only contain Bergerac DNA in the unc-85 to dpy-10 region.
