dvIs19 [(pAF15) gst-4p::GFP::NLS] III. dvIs27 [myo-3p::A-Beta (1-42)::let-851 3'UTR) + rol-6(su1006)] X. Roller with weak constitutive GFP expression. Balanced strain, segregates Rol Uncs [skn-1(zu67) heterozygotes], Rol nonUncs [skn-1(zu67) homozygotes] and dead eggs. Maintain by picking Rol Uncs. Paralyzed if upshifted as larvae to 25C.

dvIs19 [(pAF15) gst-4p::GFP::NLS] III. Oxidative stress-inducible GFP. Segregates Unc skn-1(zu67) heterozygotes, arrested eggs/larvae (nT1 homozygotes), and wild type skn-1(zu67) homozygotes (sterile). All genotypes show constitutive weak GFP expression. Upon exposure to SKN-1 inducers (e.g., azide), strong induction of GFP is observered in skn-1/+ hets; there is no induction in skn-1 homozygotes. Pick Uncs to maintain -- although this strain is nominally balanced, nT1 can break down. Reference: Dostal, V., et al. Genetics. 2010 Nov;186(3):857-66.

nmDf1 removes all four tandem paralogs of the mss family (Cre-mss-1, Cre-mss-2, Cre-mss-3, and Cre-mss-4). Male sperm is less competitive than wild-type male sperm, and females have lower brood size due to inbreeding depression. Reference: Yin D, et al. Science. 2018 Jan 5;359(6371):55-61.

The hemaglutinin (HA) epitope tag was inserted using CRISPR/Cas9 through homologous recombination. The nine amino acid HA epitope was placed between C. remanei (EM464) MSS-1 residues 22 and 23, one residue downstream of the predicted mature N-terminus after signal peptide cleavage. NOTE: nm74 was originally described as nmIs9. Derived from parental strain SB146. Reference: Yin D, et al. Science. 2018 Jan 5;359(6371):55-61.

nmIs7 [Cni-mss-1(+) + Cni-mss-2(+) + Cbr-myo-2::GFP + unc-119(+)]. Insertion site of transgene is not known, but it is not in LG III or X. Males with this transgene are more competitive in siring progeny; also a higher ratio of males in the population. Derived from parental strain CP99, which in turn was derived from AF16. Reference: Yin D, et al. Science. 2018 Jan 5;359(6371):55-61.

XX animals have no obvious phenotype: self-fertile with normal brood size. XO animals are self-fertile hermaphrodites with low brood size and some somatic gonad defects. Cbr-fem-2/+ XO animals show late-onset germline feminization. AF16 was the parental strain.

When singled, hermaphrodites should throw 2/3 hermaphrodites and 1/2 nm2 XX males. The lethal appears to balance the nm2 allele pretty well, but precise recombination mapping has not been performed. The XX males maintain their phenotypic resemblance to the unbalanced strain and are probably not fertile due to obvious gonadal deficiencies. This strain has been successfully grown at 15C and 20C. Both strains appear to have complete penetrance of the mutant phenotypes.

XX are self-fertile hermaphrodites.
