Isolated in Towers Hill State Park in WI. Males are rare. No SDS resistant dauers. Animals are osmosensitive, can be dried competely and recover in water. Rhabditidae. Previously known as Rhabditis sp.

Mesorhabditis spiculigera. Isolated in Pennsylvania. NOTE: (06/10/2016) AF72 was originally described as Mesorhabditis miotki, but K. Kiontke has determined through morphological inspection that this is actually a strain of Mesorhabditis spiculigera.

Rhabditidae: Mesorhabditis sp. Isolated in Governor Dodge State Park in South Dakota. Dark in color.

Temperature-sensitive embryonic-lethal mutant. Maintain at 15C. Shift L4s to 25C overnight to observe mutant phenotype of embryos produced by adults. Mutants lack a central spindle during early embryonic mitosis and exhibits a late cytokinesis defect (cleavage furrows regress after ingressing in nearly to the center of dividing embryonic cells). This strain can be used for CRISPR-Cas9 co-conversion. There is a causal mis-sense mutation present in zen-4(cle5), GAC to AAC (D520N), and one silent mutation, GCA to GCT at codon 519, that introduces an AluI site for RFLP analysis. A previous deposited version of this strain, zen-4(ok153), possessed two mis-sense mutations: GAC to AAC (D520N) and GAT to AAT (D735N). Reference: Farboud B, et al.

Mutants lack a central spindle during early embryonic mitosis and exhibits a late cytokinesis defect (cleavage furrows regress after ingressing in nearly to the center of dividing embryonic cells). This strain can be used for CRISPR-Cas9 co-conversion. There is a causal mis-sense mutation present in zen-4(cle10), GAC to AAC (D520N), and two silent mutations. One silent mutation is a CGA to CGG mutation at codon 523 that creates a recognition site for a Cas9 guide RNA, in order to use zen-4(cle10ts) as a CRISPR/Cas9 co-conversion marker. The other silent mutation is a GCA to GCT mutation at codon 519 that introduces an AluI site for RFLP analysis. Reference: Farboud B, et al.

armEx58 [WRM0611aH08-Del8mer + unc-119(+)]. Pick non-Unc to maintain. This strain contains a transgenic array that expresses a derivative WRM0611aH08 fosmid. The WRM0611aH08 fosmid contains the niDF199 locus (around 4 kb) that is deleted in the natural C. elegans isolate strain JU258. JU258 worms lack specific 21U-RNAs normally present in N2 worms due to this deletion of the niDF199 locus. This derivative fosmid construct lacks the upstream 8-mer motif (CTGTTTCA) next to 21U-3372. The expression of this individual 21U-RNA is lost in transgenic animals. unc-119(ed3) was crossed into JU258, the niDf199IV deletion was confirmed by PCR, and these Unc worms were used for bombardment.

This strain contains a transgenic array that expresses the WRM0611aH08 fosmid construct. This fosmid contains the niDF199 locus (around 4 kb) that is deleted in the natural C. elegans isolate strain JU258. JU258 worms lack specific 21U-RNAs normally present in N2 worms due to this deletion of the niDF199 locus. Expression of this fosmid construct in JU258 worms restores the expression of the missing 21U-RNAs in the germline, as measured by RT-qPCR. Reference: Cecere G, et al.
