ZZ21 lev-1(x21) tra-3(e2333) isolated by Jim Lewis as EMS-induced levamisole resistant derivative of N2. Found to carry a cryptic tra-3 allele by Jonathan Hodgkin. XX animals are viable hermaphrodites which produce 500 rather than 330 self-progeny; occasionally Egl; no other signs of masculinization.

Unable to propagate indefinitely: lines become sterile from F10-F28, with short telomeres and fused chromosomes. Hypersensitive to X-irradiation; weak Him phenotype; strong Him phenotype in later generations resulting from X-A fusions. Cross once or twice, freeze down many F2 mrt-2 plates, and go back to these plates every two months for fresh a mrt-2 line. A BstN1 RFLP makes the mrt-2 mutation easy to track.

EMS-induced deletion from -583 to +1017, including first two exons and part of third exon. Probable null. No obvious phenotype.

Slightly skiddy, bleach-sensitive, drug-sensitive, Bus (M. nematophilum resistant), Bah (Yersinia biofilm resistant), Leucobacter Verde1 hypersensitive. CRISPR/Cas9-induced deletion. Reference: O'Rourke et al (in preparation).

Resistant to radiation-induced apoptosis (Dam); non-Gla; very weak Rad; no gross phenotype. This strain cannot be distributed to commercial organizations. This strain cannot be used for any commercial purpose or for work on human subjects.
