VC4197 C. elegans syp-1(gk5282[loxP + myo-2p::GFP::unc-54 3' UTR + rps-27p::neoR::unc-54 3' UTR + loxP])/+ V. Show Description
Apparent homozygous lethal or sterile deletion as unbalanced heterozygote. Deletion of 1616 bp with Calarco/Colaiacovo selection cassette conferring myo-2::GFP and G418 resistance inserted at break. Pick viable fertile GFP+ animals to maintain. Left flanking sequence: ACTTCACAATTTGGGTTGACGCTCCCACTG. Right flanking sequence: CAGCCAAGTGTAGAAGTTACTCCAGTACAC. Please reference Au et al., G3 9(1): 135-144 2019 in any work resulting from use of this mutation.
AV307 C. elegans syp-1(me17) V/nT1 [unc-?(n754) let-? qIs50] (IV;V). Show Description
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.
AV271 C. elegans him-3(me80)/nT1 [unc-?(n754) let-? qIs50] (IV;V). Show Description
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.
OP230 C. elegans unc-119(ed3) III; wgIs230. Show Description
wgIs230 [syp-1::TY1::EGFP::3xFLAG(92C12) + unc-119(+)]. TY1::EGFP::3xFLAG tag inserted in frame at C-terminus of coding sequence by recombineering. Expression of transgene confirmed by GFP.
