Strains contributed by this laboratory

Strain Genotype Species Description
OK1020 cuIs36. C. elegans cuIs36 [myo-2p::GCaMP3 + rol-6(su1006)]. Maintain at 15C. Rollers. Integrated by UV/TMP irradiation of cuEx804. Reference: Kozlova AA, et al. Genetics. 2019 May;212(1):231-243. doi: 10.1534/genetics.119.302053. PMID: 30898771.
OK1083 cuEx828. C. elegans cuEx828 [ceh-19p::snb-1::GFP + rol-6(su1006)]. Pick Rollers to maintain. SNB-1::GFP expression specifically marks synaptic vesicles in the MC pharyngeal neuron. Reference: Kozlova AA, et al. Genetics. 2019 May;212(1):231-243. doi: 10.1534/genetics.119.302053. PMID: 30898771.
OK1097 tbx-2(cu32[tbx-2::TY1::GFP::FLAG]) III. C. elegans TY1::EGFP::3xFLAG tag inserted in frame at C-terminus of the endogenous tbx-2 coding sequence by CRISPR/Cas9 genome editing.
OK1114 tbx-2(cu37[tbx-2::TY1::GFP::FLAG *bx59]) III. C. elegans TY1::EGFP::3xFLAG tag inserted in frame at stop codon of the endogenous mutant tbx-2(bx59) coding sequence by CRISPR/Cas9 genome editing. Maintain at 15C. Lethal at 25C.
OK245 pyr-1(cu8) unc-4(e120)/mnC1 [dpy-10(e128) unc-52(e444)] II. C. elegans Heterozygotes are WT and segregate WT, Dpy Steriles (mnC1 homozygotes), and Unc-4 animals which have a partially penetrant Mel phenotype.
OK257 peb-1(cu9)/dpy-3(e27) unc-2(e55) X. C. elegans Heterozygotes are WT and segregate WT, DpyUncs, and peb-1(cu9) homozygotes which arrest as larvae with a stuffed pharynx, abnormal hindgut and g1 gland cell morphology, and molting defects.
OK286 pyr-1(cu8) II. C. elegans Partially penetrant Mel.
OK29 cuIs1 V. C. elegans cuIs1 [ceh-22::GFP + rol-6(su1006)]. Rollers.
OK39 cuIs2 IV. C. elegans cuIs2 [myo-2c:: GFP + rol-6(su1006)]. Rollers.
OK461 bcl-11(cu10)/unc-46(e177) dpy-11(e224) V. C. elegans Pick wild-type to maintain. Heterozygotes are wild-type and should segregate wild-type heterozygotes, bcl-11 homozygotes (L1 larval arrest with starved appearance), and Dpy Unc homozygotes (Medium Dpy, Shrinker, poor backing). Maintain by picking wild-type and scoring for proper segregation of progeny. bcl-11 homozygotes have weak pharyngeal muscle contractions and pharyngeal lumen fails to open. cu10 is a 555 bp deletion (V:6360921..6361460). Predicted bcl-11 null allele. Reference: Vilimas, Tomas. (2004). Genes regulating ceh-22 and pharyngeal development of Caenorhabditis elegans.. University of Illinois at Chicago. Thesis. https://hdl.handle.net/10027/12060
OK499 ceh-28(cu11) X. C. elegans Stuffed pharynx. Slow growth.
OK590 cuEx467. C. elegans cuEx467 [ser-7::GFP + rol-6(su1006)]. Pick Rollers to maintain. Expresses GFP exclusively in the M4 pharyngeal neuron. Reference: Ray P, et al. Dev Neurobiol. 2008 68(4): p. 421-33. PMID 18161854.
OK66 daf-4(m72) III; cuIs2/+ IV. C. elegans cuIs2 [myo-2c:: GFP + rol-6(su1006)]. daf-4(m72) is a temperature sensitive dauer constitutive mutant. Maintain at 15C. It was problematic to get cuIs2 homozygous in this background. Pick Rollers to maintain.
OK68 cuIs2 IV; daf-3(mgDf90) X. C. elegans Dauer defective. cuIs2 [myo-2c:: GFP + rol-6(su1006)]. Rollers. [NOTE: this strain was originally described as carrying daf-3(mg90), which is an old name for daf-3(mgDf90).]
OK814 nfyb-1(cu13) II. C. elegans Superficially wild-type. Reference: Milton AC, et al. Dev Biol. 2013 Oct 1;382(1):38-47.
PD8292 ceh-22(cc8266) V/nT1 [unc-?(n754) let-?] (IV;V). C. elegans Heterozygotes are Unc and segregate Uncs, non-Uncs and dead eggs.
