Sent from Burnell to J. Hodgkin in Jan. 1992. Sent to CGC in Jan. 1997.

Male-female strain. Reference WBG 9(3) 121. Isolated from sugar cane in Trinidad by D.J. Hunt (Commonwealth Institute of Parasitology). [7/7/93: Scott Baird and David Fitch question whether this strain is really C. remanei.] [7/95: Not cross-fertile with the authentic C. remanei isolated by Walter Sudhaus.] Previously called C. remanei by the CGC. Walter Sudhaus has tentatively described this strain as Caenorhabditis sp.; this description is not offical and is contigent upon its being published. See WBPaper00002633 and WBPaper00003993. sp. 4 in Kiontke and Sudhaus Wormbook Ecology chapter.

Severely uncoordinated coiler, slow growing. Useful strain for selecting non-Sup-1 suppressors of unc-17(e245). Reference: Mathews et al. (2012) PMID: 23051648.

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.
