neIs11 [myp-3::GFP::sago-1 + rol-6(su1006)]. Transgene rescues muscle RNAi defect. Rollers.

Deficient in germline and somatic RNAi.

Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP+, arrested hT2 aneuploids, and non-GFP Sterile homozygotes. qIs48 [myo-2::GFP + pes-10::GFP + ges-1::GFP]. Homozygous hT2 animals are inviable. May have him-8(e1489) in background, but unsure.

Heterozygotes are Unc. csr-1(tm892) homozygotes are non-Unc and Sterile.

neIs20 [pie-1::3xFLAG::csr-1 + unc-119(+)]. Partially rescues sterility (60% dead embryos). Unknown if unc-119(ed3) is still present in the background. Reference: Claycomb J, et al. 2009 Cell 139:123-34.

neIs20 [pie-1::GFP::csr-1 + unc-119(+)]. Partially rescues sterility (60% dead embryos). Unknown if unc-119(ed3) is still present in the background. Reference: Claycomb J, et al. 2009 Cell 139:123-34.

axIs36 [pes-10::GFP]. Heterozygotes are Unc and sensitive to ivermectin. Segregates csr-1 homozygotes (sterile, non-Unc, resisitant to ivermectin), dead embryos, and Unc heterozygotes. Maintain by picking Uncs. Do not distribute this strain; other labs should request it directly from the CGC. Reference: Claycomb JM, et al. Cell. 2009 Oct 2;139(1):123-34.

Temperature-sensitive male sterility. Maintain at 20C. Reference: Conine CC, et al. Proc Natl Acad Sci U S A. 2010 Feb 23;107(8):3588-93.

Heterozygotes are Unc and segregate Unc, WT which give only dead eggs, and dead eggs. Zygotic phenotype: 100% of gex-3 homozygotes become Egl although they all make a normal looking L3/L4 vulva. Embryonic phenotype: complete loss of morphogenesis - hypodermal cells fail to intercalate or migrate. Received new stock from Erik Lundquist 11/2003.

Defective in mitotic spindle orientation. Mis-segregation of germline proteins PGL-1 and PIE-1. Change of cell fate (extra-gut, no gut). Defective in chromosome segregation. Temperature sensitive; maintain at 15C; 100% lethal at 25C.

neIs2 [wrm-1::GFP + rol-6(su1006)] IV. Rollers.

Pick GFP+ to maintain. sprDf1 is a ~0.25 Mb microdeletion allele on the left arm of chromosome V that removes 32 adjacent protein-coding genes, including mex-5. Heterozygous animals (GFP+) are fertile, but sometimes die by bursting, will have polynucleated embryos, and form uterine tumors ~6 days after hatching. sprDf1 homozygotes (GFP-) have maternal effect lethality, are small, sterile, form large uterine tumors that consist of poly nucleated embryos, have squashed vulvas, are uncoordinated, and die by bursting within eight days of hatching. nT1 homozygotes are inviable (dead eggs). Reference: Antkowiak KR, et al. G3 (Bethesda). 2023 Nov 13:jkad258. doi: 10.1093/g3journal/jkad258. PMID: 37956108.

mCherry tag inserted at N-terminus of endogenous pgl-1locus in parental strain DG4269. Reference: Brown HE, et al. Development. 2025 Sep 1;152(17):dev204740. doi: 10.1242/dev.204740. PMID: 40787769.

neSi101 [sun-1p::TIR1::mRuby::eft-3 3'UTR + Cbr-unc-119(+)] IV. GFP reporter inserted into C-terminus of endogenous oma-1 locus. A triple arginine motif upstream of the oma-1 tandem zinc finger domain is mutated to three alanines. AID* degron tag (IAA17) inserted into the endogenous oma-2 locus. When OMA-2 is present, this mutant does not appear to have obvious phenotypes. Auxin-inducible depletion of OMA-2 causes embryonic lethality: animals lay low numbers of nonviable embryos that are often polynucleated and have weak chitin shells.

n1790 causes a partially penetrant "rod-like" larval lethal phenotype (17% at 20C) and a partially penetrant vulvaless defect (50% at 20C). A Smg mutation enhances these phenotypes. The n1790 mutation is a nonsense change at codon 352.

n2515 suppresses the let-60(gf) Muv phenotype. Isolation of lin-1 causes no significant vulval defect; it is a missense mutation that changes Proline 384 to Leucine. dpy-13 is a linked marker.

Homozygous maternal effect lethal mutation balanced by GFP-marked translocation. Heterozygotes are WT with pharyngeal GFP signal, and segregate WT GFP, arrested nT1[qIs51] aneuploids, and non-GFP am315 homozygotes (maternal effect lethal). Homozygous nT1[qIs51] inviable.
