Heterozygotes are mostly non-Muv (about 20% will be Muv because n1700 is semi-dominant) and non-Unc. Hets segregate Twitchers which die at various larval stages or as Vul adults, because of the maternal effect rescue of n1531 by n1700. The Twitchers will not give viable progeny. Hets also segregate DpyMuvs. The strain segregates males which will mate, though not very well.

Heterozygotes are weak Muv and segregate weak Muv, Muv Twitchers, and Dpy Vuls whose progeny are larval lethal. sy100 is a dominant negative allele of let-60. n1046 is a gain-of-function allele of let-60. Do not distribute this strain; other labs should request it from the CGC.

Pick wild type animals to maintain.

This cosmid lacks the 3' end of the unc-22 gene while XDM23 lacks the 5' end of unc-22, but following injection an extrachromosomal array was formed that included at least one functional unc-22 gene.

Heterozygotes are WT and segregate WT, Unc-36 and dead eggs. Maintain by picking WT. Original isolation: BO strain BC1261 unc-22(s727) hermaphrodite heat shocked for 1 hour at 34C. Crossed to N2 strain BC1270 unc-22(s7) unc-31(e169)/nT1 IV; +/nT1 V. Picked individual WT hermaphrodites. Screened for the absence of gravid Unc-22. Retained strain as BC1379. Balanced over eT1: BC1379 unc-22(s727)[BO]/nT1[N2] IV; sDf31[BO]/nT1[N2] hermaphrodite crossed to BC 1265 dpy-18(e364)/eT1 III; unc-46(e177)/eT1 V. Pick WT hermaphrodites that twitch in 1% nicotine. Retained one strain that segregated Unc-36 as BC1428. Pseudolinked sDf31 to dpy-18: BC1428 +/eT1 III; sDf31[BO]/eT1 V crossed to BC 1265 dpy-18/eT1 III; unc-46/eT1 V male. Picked WT hermaphrodite F1. From strains segregating Unc-36 but no Dpy or Unc-46 or DpyUnc-46, cross WT hermaphrodites to BC1265 males. From strains producing Dpy, crossed individual WT males to BC70 eT1;eT1. From each cross, crossed WT X WT. Kept one strain producing on Dpy or DpyUncs as S-H716 male. Picked one hermaphrodite to start BC1519. Comments: 1) The LGV region balanced by eT1 should be all BO. 2) Probably the rest of the genome still has a considerable amount from BO since it was crossed to N2 only 4 times. This strain was generated by the Genetic Toolkit project, which should be acknowledged in any publications resulting from its use: The Genetic Toolkit is funded by the NIH National Center for Research Resources (NCRR) (USA) to Ann M. Rose, David L. Baillie, and Donald L. Riddle. Report all experimental results to David Baillie.

Million Mutation Project strain. This strain was isolated after ENU mutagenesis of VC2010, propagated clonally through F10 to drive mutations to homozygosity, and subjected to whole-genome sequencing. It is homozygous for a large number of mutations determined from sequence data. It may also carry large copy number variations that are not homozygous. Alleles numbered between gk100000 and gk962522 are homozygous; those numbered from gk962523 up should be assumed to be non-homozygous. A graphical representation of these large copy number differences can be seen in the Plot section for each strain on the MMP web site ( http://genome.sfu.ca/mmp/). Note that this strain is known to segregate homozygous unc-22 and strong Dumpy progeny (gene not identified). The strain was validated by PCR and sequencing of the allele gk421264 in D2030.11. Attribution: This strain was provided by the C. elegans Reverse Genetics Core Facility at the University of British Columbia, which is part of the international C. elegans Gene Knockout Consortium, which should be acknowledged in any publications resulting from its use.
