C. briggsae |
Cbr-she-1(v35) IV; mfIs42. Show Description
mfIs42 [Cel-sid-2(+) + Cel-myo-2::dsRed]. Maintain at 15C. Feminization is partially-penetrant at 15C; most hermaphrodites are somewhat self-fertile and can lay small broods. Can be maintained by crossing with male siblings. Feminized C. briggsae strain made susceptible to RNAi knock-down by feeding dsRNA due to the transgenic expression of C. elegans SID-2. Generated by crossing parental strains JU1018 with RE665. Reference: Booth LN, eLife 2019 Jul 8;8:e46418. PMID: 31282863.

C. elegans |
ieDf2 [unc-119+]/mIs11 IV. Show Description
mIs11 [myo-2p::GFP + pes-10p::GFP + F22B7.9::GFP]. Heterozygotes are wild-type with dim GFP signal in the pharynx. mIs11 homozygotes are wild-type with bright GFP in the pharynx. ieDf2 homozygotes (non-GFP) develop normally but produce 97.5% inviable embryos and a high frequency of males among the surviving self-progeny. Pick WT with dim GFP+ in pharynx to maintain. mIs11 homozygotes will quickly overtake the population if not selected against. GFP expression in 4-cell embryos, pharyngeal muscle and gut. ieDf2 is a deficiency of zim-1, zim-2, zim-3, and him-8 generated by MosDel, resulting in single-copy insertion of a copy of the C. briggsae unc-119 gene on Chromosome IV. The deletion spans the sequences from the beginning of the zim-1 coding sequence through the ttTi22866 Mos1 insertion site.

CGC2 |
C. briggsae |
C. briggsae wild isolate. Show Description
C. briggsae reference strain formerly known as PB420. Derived from C. briggsae Gujarat, the strain that later was named G16 and then AF16. PB420 was frozen (as C. briggsae Gujarat) 22 March 1991, thawed 15 June 2020 and sent to the CGC 1 July 2020. It may be considered ancestral to AF16 and was renamed to distinguish it from AF16 strains that have been maintained in laboratory cultures. Reference: Fodor A, et al.

C. briggsae |
Cbr-puf-2(nm66)/Cbr-dpy-?(nm4) II. Show Description
Larval-lethal puf-2 deletion allele. Heterozygotes are WT (slightly Dpy) and segregate 25% Dpy, 50% wild-type heterozygotes, and 25% larval lethal (arrest L1-L2). Maintain by picking WT and checking for correct segregation of progeny. Map distance between nm4 and nm66 has not been preciely determined, but is tight enough that >90% of non-Dpy non-Lva progeny from double-heterozygotes retain the parental genotype.

Cbr-unc-119(nm67) III; nmIs7. Show Description
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.

Cbr-fem-2(nm27) III. Show Description
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.

C. briggsae |
Cbr-tra-1(nm2)/Cbr-let(nm28) III. Show Description
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.

C. briggsae |
Show Description
Isolated by Michael Ailion from rotting apricot from home of Wayne Davis and Danielle Endres in Salt Lake City, Utah, 8/4/2006, under tree on north side of house. Coordinates: 40° 42' 26.16" N, 111° 52' 3.27" W. Animals move very rapidly. Strain started from a single L4 hermaphrodite and grown three generations before freezing. 18S rDNA sequence differs from C. briggsae NCBI entry (PB102), but is identical to the 18S sequence of AF16, HK104, PB800 and VT847. Cross-fertile with AF16.

EG4207 |
C. briggsae |
Show Description
Mixed "strain" started from many different worms that emerged from the same apricot that gave rise to strain EG4181. Some worms emerged as dauers, but there were also L4s and adults. Consists of a mix of the worms that came from the apricot to try to maintain as much diversity as possible in the population and thus is not a true strain in the traditional sense. It will be sent as contaminated worms since it cannot be cleaned up without going through a bottleneck.

Crispr/Cas9 engineered mutation in unc-119. ox819 is an 11 bp deletion causing a frameshift after V110 (UNC-119a) and then appends 29 out-of-frame amino acids before a stop codon. unc-119(ox819) animals are phenotypically identical to unc-119(ed3) animals and can be rescued by expression of the smaller C. briggsae unc-119 gene (Cbr-unc-119).
