Levamisole resistant. Recessive. Marginally Unc-No sin wave. WT adults.

ccIs55 [unc-54::lacZ + sup-7(st5)] V. Resistant to 1 mM levamisole.

Temperature-sensitive allele. Can be grown at 20C with reduced fertility. Defects in pachytene progression, small oocyte formation and Emo are highly penetrant at 25C. ok154 is a null allele; 1504 bp deletion from -156 bp to +1348 bp, removes the start codon.

Ectopic ERK MPK-1 (detected by dpMPK-1 immunostaining) in the loop region. Reference: Proc Natl Acad Sci USA. Das D, et al. 2022 Jan 18;119(3):e2113649119. PMID: 35022236

Intragenic revertant of dominant mutation e665. Slight uncoordinated phenotype.

Short, blunt head. Dominant.

Phenotypically wildtype XX hermaphrodite at 20C; poor viability and fertility at 25C. Rare XO animals are hermaphrodite due to suppression of amber mutation e2115 and consequent transformation of XO due to tra-2(e2046) gain-of-function. Reference: Hodgkin & Albertson (1995) PMID: 8647390.

Viable Dpy at 15C. Extreme Dpy or L1 lethal at 25C.

Small, blunt rounded nose; heterozygous e2656/+ are animals similar, XO males can mate. Molecularly and phenotypically different from sma-8(e2111).

rde-1(ar660)[rde-1(lox2272-flexon-lox2272)]. 9th intron of rde-1 replaced with a flexon - an artificial exon flanked by artificial introns that each contain a lox2272 site (a flexon). Severely reduces rde-1 function, function can be restored upon excision of the flexon by Cre recombinase. Reference: Shaffer JM & Greenwald I.

CRISPR-engineered KO strain of haps-1 made by knock-in of tandem stop codons to the first exon of endogenous haps-1 locus. haps-1(C48B6.3) is the C. elegans ortholog of human HAPSTR1. haps-1(ljt1) is superficially wild-type when cultured at 20C, but is hypersensitive to paraquat (redox stress), MLN4924 (neddylation inhibition), and camptothecin (genotoxic stress).
