Him. Temperature-sensitive sterile. Small brood size even at permissive temperatures; pick fertile animals and maintain at 15C. Worms lacking spe-45 function produce morphologically normal and motile sperm that cannot fuse with oocytes despite direct contact in the reproductive tract. spe-45 hermaphrodites and males are subfertile at 16C and sterile at 25C.

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.

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.
