Rearrangement Information

NamenT1 View on WormBase
DescriptionRecommended use: General balancing, strain maintenance, mutant screens. reciprocal translocation:right arm of IV and left arm of V; N300 Handling: Easy to manipulate. Heterozygous males mate well. Vulvaless homozygous hermaphrodites completely unable to mate. Cause of vulvaless phenotype unknown. Translocation may break down spontaneously, but analysis of such events is lacking. Heterozygous strains occasionally begin to segregate large numbers of sick-looking progeny while appearing to remain heterozygous, or they occasionally begin to give larger broods (Schein and Baillie, unpublished results). nT1[qIs51] carries an integrated pharyngeal GFP element, and is homozygous inviable; this variant appears to be transferred to male cross progeny more frequently than to hermaphrodite cross progeny. Summary: Translocation, moderately well characterized, very stable. Very effective balancer for right portion of LG IV from right end through unc-17, and for left portion of LG V from left end through unc-76.

Strain Genotype Species Description
AMH50 juIs76; bec-1(ok691) IV/nT1 [qIs51] (IV;V). C. elegans juIs76 [unc-25p::GFP + lin-15(+)] II.  Heterozygotes are wild-type with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-pharyngeal GFP bec-1 homozygotes. Homozygous nT1[qIs51] inviable. Pick WT GFP and check for correct segregation of progeny to maintain.
AP36 mep-1(ok421)/nT1 [qIs51] (IV;V). C. elegans qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok421 homozygotes, wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Received new stock 12/02.
ATD1 unc-119(ed3) III; sqt-3(sc8) par-1(b274) IV/nT1[unc-?(n754) let-?] (IV;V); zuIs45 V. C. elegans zuIs45 [nmy-2p::nmy-2::GFP + unc-119(+)] V. Balanced heterozygotes are Unc and segregate Unc (heterozygotes), Rol Par (sqt-3 par-1 homozygotes; maternal effect lethal), and dead eggs (nT1 homozygotes). NMY-2::GFP is expressed in the germline and somatic gonad. Cross of JJ1473 and KK288. Unknown if unc-119(ed3) is still present or homozygous in background. Reference: Small LE & Dawes AT. Mol Biol Cell. 2017 Aug 1;28(16):2220-2231.
AV106 spo-11(ok79) IV/nT1 [unc-?(n754) let-?] (IV;V). C. elegans Heterozygotes are Unc and segregate Uncs (heterozygotes), non-Unc spo-11 homozygotes, and dead eggs (nT1 homozygotes). spo-11 homozygotes produce an average of ~200 fertilized eggs but only about 0.1 progeny survive to adulthood. When mated to N2 males, spo-11 homozygotes will produce at least 5-10 cross progeny.
AV112 mre-11(ok179) IV/nT1 [unc-?(n754) let-?] (IV;V). C. elegans Heterozygotes are Unc and segregate Uncs (heterozygotes), non-Unc mre-11 homozygotes, and dead eggs (nT1 homozygotes). mre-11 homozygotes produce about 200 fertilized eggs but only about 2-3% of these eggs survive to adulthood (this mutation cannot be maintained in a homozygous condition). Occasionally non-Unc progeny that do not demonstrate the mre-11(ok179) mutant phenotype arise when grown in large liquid cultures. mre-11 is the predicted gene ZC302.1

C. elegans Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc spo-11(me44) homozygotes, and dead eggs (nT1 homozygotes). spo-11(me44) homozygotes are viable and produce more than 90% dead eggs (a large fraction of the survivors are males — strong Him phenotype); cytologically they lack chiasmata in diakinesis-stage oocytes and lack RAD-51 foci. Maintain by picking Unc.
AV271 him-3(me80)/nT1 [unc-?(n754) let-? qIs50] (IV;V). C. elegans Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc him-3(me80) homozygotes, and dead eggs (nT1 homozygotes). him-3(me80) homozygotes are viable and non-Unc. They produce more than 85% dead eggs and a large fraction (11%) of the survivors are males (Him phenotype). Cytologically they exhibit a reduced level of HIM-3 loading and fewer stretches of SYP-1 than WT. In diakinesis-stage oocytes, they contain a mixture of bivalents and univalents. Maintain by picking Unc.
AV276 syp-2(ok307) V/nT1 [unc-?(n754) let-?(m435)] (IV;V). C. elegans Balanced heterozygotes are Unc and segregate Unc (heterozygotes), non-Unc syp-2(ok307) homozygotes, and dead eggs (nT1 homozygotes). syp-2(ok307) homozygotes are viable and non-Unc. They produce 96% dead eggs and 44% males; cytologically they lack chiasmata in diakinesis-stage oocytes, exhibit persistent polarized nuclear organization during earlier meiotic prophase, lack synaptonemal complexes, and exhibit unstable pairing of homologous chromosomes.
AV307 syp-1(me17) V/nT1 [unc-?(n754) let-? qIs50] (IV;V). C. elegans Balanced heterozygotes are GFP+ Unc and segregate GFP+ Unc (heterozygotes), non-GFP non-Unc syp-1(me17) homozygotes, and dead eggs (nT1 homozygotes). syp-1(me17) homozygotes produce 95% dead embryos and 38% males. Cytologically they lack chiasmata in diakinesis-stage oocytes, exhibit persistent polarized nuclear organization during earlier meiotic prophase, lack synaptonemal complexes, and exhibit unstable pairing of homologous chromosomes. qIs50 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 (F22B7.9) driving GFP in the intestine.
AV473 rad-50(ok197) V/nT1 [qIs51] (IV;V). C. elegans qIs51 [myo-2p::GFP + pes-10p::GFP + F22B7.9p::GFP]. Heterozygotes are wild-type GFP+ and segregate non-GFP ok197 homozygotes (viable, sterile), wild-type GFP+ heterozygotes, and arrested nT1[qIs51] aneuploids. rad-50 homozygotes are viable, produce more than 95% dead eggs and a large fraction of the survivors are male (Him phenotype). Pick wild-type GFP+ and check for correct segregation of progeny to maintain. Reference: Hayashi M, et al. PLoS Genet. 2007 Nov;3(11):e191.
