CC-314 dk97 mt-Locus: not mapped
Source: Isolated by Andrew Wiseman in the Boynton-Gillham laboratory, nitrosoguanidine-induced in wild type mt-. This is the original mutant.
Comment: This strain has reduced levels of cyanide-sensitive respiration and no detectable cytochrome oxidase activity, but essentially normal mitochondrial ultrastructure. At last check, the strain still showed a very clean dark-dier phenotype.
