Strain Genotype Species Description
CER123 ham-3(he159) III/hT2 [bli-4(e937) let-?(q782) qIs48] (I; III). C. elegans Heterozygotes are WT, GFP+ in the pharynx and segregate WT (GFP+ in the pharynx), dead eggs (homozygotes for hT2) and ham-3(he159) homozygotes, which are Sma, Egl, Adl, Pvl. Maintain by picking GFP+ worms and checking for correct segregation, since the hT2 balancer is lost at low frequencies. he159 allele was isolated by John Satterlee from a deletion library at Sander van den Heuvel's lab. Reference: Ertl I, et al. Genetics. 2016 Mar;202(3):961-75.
CER162 unc-119(ed3) III; cerIs7. C. elegans cerIs7 [lsm-1::GFP(fosmid) + unc-119(+)]. cerIs7 rescues all the temperature-sensitive phenotypes of lsm-1(tm3585). Reporter contains full-length lsm-1 tagged with GFP. GFP was inserted into a fosmid containing lsm-1. GFP is expressed diffusely in the cytoplasm of somatic cells. Under heat shock conditions, GFP accumulates forming cytoplasmic foci. Reference: Cornes E, et al. RNA. 2015 Sep;21(9):1544-53.
CER178 nfki-1(cer1) X. C. elegans cer1 is a CRISPR-generated 368 bp deletion removing intron 2 and part of exon 3, creating a premature stop codon. Low penetrance of developmental defects such as abnormal L1 morphology, aberrant gonad migration, and an abnormal number of distal tip cells. Reference: Brena D, et al. Sci Rep. 2020 Sep 30;10(1):16153.
CER187 nfki-1(cer2) X. C. elegans cer2 is a CRISPR-generated 438 bp deletion + 50 bp insertion removing intron 2 and part of exon 3, creating a premature stop codon. Low penetrance of developmental defects such as abnormal L1 morphology, aberrant gonad migration, and an abnormal number of distal tip cells. Reference: Brena D, et al. Sci Rep. 2020 Sep 30;10(1):16153.
CER244 ikb-1(cer9) I. C. elegans cer9 is a CRISPR-generated 462 bp deletion at the beginning of the ikb-1 coding sequence, including the start codon (no transcript should be synthesized). Low penetrance of developmental defects such as abnormal L1 morphology, aberrant gonad migration, and an abnormal number of distal tip cells. Reference: Brena D, et al. Sci Rep. 2020 Sep 30;10(1):16153.
CER348 trxr-1(cer35[Sec666C]) IV. C. elegans Missense mutation selenocysteine to cysteine. Resistant to cisplatin exposure. Primers to genotype this missense mutation and other silent mutations: [Common Fw: GGCTTCCACATTCTCACTCC] [RV wildtype: CTTAACCTCAGCAACCAGAA] [RV Sec to Cys: CTTAACCGCAACATCCGCTG] Reference: García-Rodríguez FJ, et al. Dis Model Mech. 2018 Jun 21;11(6).
CER36 lsm-1(tm3585) II; lsm-3(tm5166) IV. C. elegans Maintain at 15C. Temperature sensitive. Reduced brood size, Sma. Reference: Cornes E, et al. RNA. 2015 Sep;21(9):1544-53.
CER374 trxr-1(cer55[Sec666X]) IV. C. elegans Missense mutation engineered by CRISPR removes a selenocysteine to place a stop codon. Resistance to cisplatin exposure. Primers to genotype the cer55 and other silent mutations: [Common Fw: #1224 GGCTTCCACATTCTCACTCC] [RV wildtype: #1414 cTTAACCTCAGCAACCAGAA] [RV Sec to STOP: #1421 CTTAACCTTAACATCCGCTG] Reference: García-Rodríguez FJ, et al. Dis Model Mech. 2018 Jun 21;11(6).
CER4 rsr-2(tm2625)/mIn1 [dpy-10(e128) mIs14] II. C. elegans mIs14 [myo-2::GFP]. Heterozygotes are WT and GFP+ with signal in the pharynx. Heterozygote animals segregate heterozygotes (WT GFP+), mIn1 homozygotes (Dpy and brighter GFP+), and rsr-2(tm2625) homozygotes (Lva non-GFP). Pick WT GFP+ animals and check for proper segregation of progeny to maintain. Reference: Fontrodona L, et al. PLoS Genet. 2013 Jun;9(6):e1003543.
CER41 unc-119(ed3) III; cerIs2. C. elegans cerIs2 [lsm-4p::lsm-4::GFP::lsm-4 3'UTR + unc-119(+)]. Reporter contains full-length lsm-4 tagged with GFP. GFP was inserted into a fosmid containing lsm-4. Ubiquitous nuclear GFP expression in somatic and germ cells under normal growth conditions. Cytoplasmic GFP accumulation after exposure to heat-shock. Reference: Cornes E, et al.

CER529 sftb-1(cer144) III.
