Strain Genotype Species Description
HA2825 smn-1(ok355) I/hT2 [bli-4(e937) let-?(q782) qIs48] (I;III); rtSi10 IV; nuIs175 X. C.elegans rtSi10 [smn-1p::smn-1 + Cbr-unc-119(+)] IV. nuIs175 [myo-2p::RFP + unc-129p::RFP::snb-1] X. rtSi10 transgene partially rescues smn-1(ok355): smn-1 homozygotes normally arrest as larvae, but somatic defects, including late larval lethality, are ameliorated by rtSi10. Sterility in smn-1(ok355) homozygotes is not rescued by rtSi10. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested hT2 aneuploids, and non-GFP ok355 homozygotes (sterile due to partial rescue by rtSi10). Homozygous hT2[bli-4 let-? qIs48] inviable. Note: qIs48 has been observed to recombine off hT2, typically leaving behind a functional homozygous viable hT2 with Bli-4 phenotype. Pick WT GFP and check for correct segregation of progeny to maintain. Reference: O'Hern PJ, et al. eLife 2017;6:e20752 doi: 10.7554/eLife.20752
LM99 smn-1(ok355) I/hT2 [bli-4(e937) qIs48] (I;III). C. elegans C41G7.1. smn-1 homozygotes arrest as larvae. Segregates WT glowing hets, non-glowing arrested larvae, very rare homozygous hT2 glowing animals, and dead eggs (aneuploids). URL: http://www.celeganskoconsortium.omrf.org.
