Rearrangement Information

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.

EKM4 capg-1(tm1514) 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 tm1514 homozygotes (sterile, tm1514 m+z- are larval lethal). Homozygous hT2[bli-4 let-? qIs48] inviable. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: Csankovszki G, et al. (2009) Curr Biol 19(1):9-19.
EL302 ego-1(om71) unc-29(e193)/hT2 [dpy-18(h662)] I; +/hT2 [bli-4(e937)] III. C. elegans Heterozygotes are WT and segregate WT, Sterile Uncs and Dpys. bli-4 is suppressed by dpy-18 in hT2 homozygotes-only see a very few DpyBli.
EL329 ego-1(om58)/hT2 [dpy-18(h662)] I; +/hT2 [bli-4(e937)] III. C. elegans Heterozgyotes are WT and segregate WT, Steriles and Dpys. The Steriles produce small, abnormal oocytes; some dead embryos are produced in late adulthood. bli-4 is suppressed by dpy-1 in hT2 homozygotes-only see a very few DpyBli. om58 previously called ego-6(om58).
EL391 ego-1(om84) unc-29(e193)/hT2 [dpy-18(h662)] I; +/hT2 [bli-4(e937)] III. C. elegans Heterozygotes are WT and segregate WT, mild Unc that are Sterile, and Dpys. bli-4 is suppressed by dpy-18 in hT2 homozygotes-only see a very few DpyBli.
EU1513 aph-1(or28)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; lin-2(e1309) X. C. elegans or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. or28 is a G to D mis-sense mutation at amino acid position 123.
EU1514 aph-1(or28)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; him-8(ec56) IV; lin-2(e1309) X. C. elegans or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets fill up with a mix of dead embryos and larvae [11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2; vulvaless due to homozygous lin-2(e1309) mutation; about 10% of lin-2(e1309) worms are leaky and lay eggs/can be mated into]. The homozygous or28 hermaphrodites fill up with dead embryos. The lin-2 background helps to score embryonic lethality for both heterozygotes and or28 homozygotes. Strain produces a lot of males due to him-8(ec56). or28 is a G to D mis-sense mutation at amino acid position 123.
EU1515 aph-1(or28)/hT2 I; +/hT2 [bli-4(e937) let-?(h661)] III; him-8(ec56) IV. C. elegans Him. or28 is a non-conditional maternal-effect embryonic lethal mutant ; the anterior pharynx is absent. and embryonic lethality is 100% penetrant. Pick single WT heterozygous hermaphrodites to maintain strain; these hets produce 11/16 dead embryos due to aneuploidy from translocation segregation and lethal homozygous hT2. The homozygous or28 hermaphrodites produce all dead embryos with defective pharyngeal development. or28 is a G to D mis-sense mutation at amino acid position 123.
