kasEx147 [oig-1p(1.6kb)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 1.6kb cis-regulatory region (-2.6-1.0kb) upstream of oig-1 was fused to GFP with the unc-54 3'UTR. oig-1 uses mulitple cis-regulatory regions to achieve different expression patterns in motor neurons; this construct drives expression specifically in cholinergic motor neurons. Construct was injected into N2 worms. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx149 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 200bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is been abolished; expression was observed specifically in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

kasEx151 [oig-1p(2.6kb_del)::GFP::unc-54 3'UTR + myo-2p::GFP]. Pick worms with GFP+ pharynx to maintain array. Unc. 2.6kb cis-regulatory region with 300bp deletion removing predicted LIN-39 binding site upstream of oig-1 was fused to GFP. Expression of oig-1::GFP in GABAergic motor neurons is retained, but eliminates ectopic expression in cholinergic motor neurons of the ventral nerve cord. Reference: Feng W, et al. Elife. 2020 Jan 3;9. pii: e50065. doi: 10.7554/eLife.50065.

ieSi57 [eft-3p::TIR1::mRuby::unc-54 3'UTR + Cbr-unc-119(+)] II. The endogenous unc-3 locus is tagged with mNeonGreen and AID degron. mNeonGreen expression is seen in the cholinergic motor neurons, command interneurons, and ASI. Reference: Patel T & Hobert O. eLife 2017.

WT PHENOTYPE.

Dpy. Unc. meT7 is an end-to-end-to-end fusion of chromosomes III, X, and V. The right end of III is fused to the left end of X, and the right end of X is fused to the left end of IV. Constructed by crossing eT5 and mnT12. meT7 homozygotes produce 92% viable progeny. meT7 heterozygotes are Him and produce many dead eggs.

Unc. Temperature sensitive Muv.

n1279 is lethal. Animals which are alive contain the duplication. n1279 pka sup-20.

Unc. Muv. Do not distribute this strain; other labs should request it from the CGC. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.

Animals with the duplication are WT and segregate WT, sterile and Pats. Strain can be propagated by chunking.
