Unc-22 twitcher. This strain was isolated after ENU mutagenesis of VC2010 and subjected to whole-genome sequencing (Flibotte et al., Genetics 185: 431 - 441 (2010). In addition to unc-22(gk2608gk2609), it is homozygous for 224 other mutations determined from sequence data. All mutations are annotated in WormBase.

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.

Homozygous lethal or sterile deletion balanced by tmC3. Deletion of 2147 bp with Calarco/Colaiacovo selection cassette conferring myo-2::GFP and G418 resistance inserted at break. Pick viable fertile GFP+ animals to maintain; homozygous tmC3 carries myo-2p::mCherry and is Unc-23 Lon-3. Left flanking sequence: GAAAATAGGCAAAAATATTAAACCGTGAAG; Right flanking sequence: GGAAGTGTCATGTTATGATTGACTCCGAAC.

jcIs1 [ajm-1::GFP + unc-29(+) + rol-6(su1006)] IV. Loss of cell fusion in hypodermis (epithelial fusion failures). Viable and fertile as homozygotes. Tail-spike defect in all young larvae, less visible in older larvae and adults. oj55 appears to cause incomplete loss of function, as many cells fuse in postembryonic development. Homozygous males have tail and mating defects. ES=3. Cloned: ORF C26D10.5 encodes a type-I membrane glycoprotein with a single TM domain. ajm-1 was formerly known as jam-1 (Junction Associated Protein) and "the gene encoding the antigen recognized by the monoclonal antibody MH27." jcIs1 consists of pJS191, C45D3 and pRF4.
