CC-312 dk76 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 and cytochrome oxidase, but essentially normal mitochondrial ultrastructure. At last check, the strain still showed a dark-dier phenotype, with very slow growth at most in the dark.
