| Species | Rhabditella axei |
| Genotype | Rhabditella axei wild isolate. |
| Description | Formerly known as Rhabditis axei. Isolated by Elie S. Dolgin in 2006 from fungus at Limuru, Kenya (1º05'S 36º39'E); isolate number LI-OM-B-1&4. First frozen by Fitch laboratory 9/5/2006. Gonochoristic. Grows well on NGM plates and OP50 at 20-25C. Freezes easily with C. elegans protocols with >20% viability. DF5098 was verified to be R. axei by intercrossing it with DF5006 and observing that their resulting F1 and F2 hybrid offspring were healthy and fertile. At 33C, DF5098 can live for up to three days, although they developmentally arrest as late larvae or young adults, fail to produce offspring, and eventually die; in contrast, DF5006 either dies or arrests as first-stage (L1) larvae. Returning DF5098 to 20C from 33C rescues them from developmental arrest and death, and allows them to become fertile adults; in contrast, when DF5006 L1 larvae are returned to 20C, they sometimes grow to later larvae, but never grow to fertile adults. Thus, DF5098 shows clearly superior resistance to heat over DF5006; it shows somewhat lower fertility than DF5097 (which also withstands 33C) after being returned to 20C. |
