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.

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(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. Reference: Cecere G, et al. Mol Cell. 2012 Sep 14;47(5):734-45.

armEx53 [WRM0611aH08 + unc-119(+)]. Pick non-Unc to maintain. 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.
