NamehT2 View on WormBase
DescriptionHandling: Easy to manipulate. Heterozygous males, and homozygous males of original isolate, mate well. Homozygous Bli-4 phenotype completely suppressed in dpy-5 and dpy-18 variants. Rare exceptional progeny carry one half-translocation as a complex free duplication. Mutations have been observed to become unbalanced at low frequency, but the mechanism is not fully understood. The dpy-18(h662) variant is very mildly Dpy as a homozygote. hT2[bli-4(e937) let-?(q782) qIs48] carries an integrated pharyngeal GFP element; the lethal mutation in this variant has been observed to recombine away, leaving hT2[bli-4(e937) qIs48] that apparently retains balancer activity. Growth characteristics: Original isolate homozygous viable with Bli-4 phenotype. Recommended use: General balancing, strain maintenance. Summary: Reciprocal translocation, well characterized, stable. Effective balancer for left portion of LG I from left end through unc-101, and right portion of LG III from right end through dpy-17. hT2(I) is LG III (right) translocated to LG I (right), disjoins from normal LG I. hT2(III) is LG I (left) translocated to LG III (left), disjoins from normal LG III.

Strains carrying this rearrangement

Strain Genotype Species Description
YG1046 baf-1(gk324) III/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III); eff-1(ok1021) II; syIs78. C. elegans syIs78 [ajm-1::GFP + unc-119(+)] is probably on LG I (not on II, III, V or X). Heterozygotes are slow-growing DpyUnc with cell fusion problems and pharyngeal GFP signal. Segregates arrested hT2 aneuploids, and non-GFP DpyUnc gk324 homozygotes (Sterile, Dpy and Unc). All worms express ajm-1::GFP(Junction Associated Protein). qIs48 is an insertion of ccEx9747 with markers: myo-2::GFP expressed brightly in the pharynx throughout development, pes-10::GFP expressed in embryos, and a gut promoter driving GFP in the intestine, and is homozygous lethal.
YHS2 cdc-25.1(bn115) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). C. elegans Homozygous sterile deletion 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 bn115 homozygotes (sterile). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: Kim J, et al. (2009) Mol Cell 28:43-8.
ZT2 drh-3(fj52) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III). C. elegans Heterozygotes are WT. drh-3 homozygotes are sterile. the fj52 mutation deletes a 405 bp region including the promoter, the first exon and half of the second exon. The deletion can be checked by PCR with the following primers: TTTATTGATTCCGCCGTTGCTC and TGCAGCTCCAGCCACTCTATCA. The fj52 mutation was isolated from a deletion mutant libray of the K. Nishiwaki group. Homozygous hT2[bli-4 let-? qIs48] inviable.
