C. briggsae strains available at the CGC

Strain Genotype Description
CP161 Cbr-unc-119(nm67) III; nmIs7. 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.
PB420 C. briggsae wild isolate. PB420 is 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. Nematologica 1983 92: 203-217. doi:10/1163.187529283X00456
ABR156 Cbr-she-1(v35) IV; mfIs42. 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.

OH17874 Cbr-dpy-10(ot1210) II. Dpy Rol. Heterozygotes are Left-handed Rol. R92C mutation in Cbr-dpy-10 generated via CRISPR/Cas9. Homologous to the C. elegans dpy-10(cn64) mutation.
