CC-311 dk74 mt-

Locus: not mapped; original mutant showed non-Mendelian segregation

Source: Isolated by Andrew Wiseman in the Boynton-Gillham laboratory, nitrosoguanidine-induced in wild type mt-. This is the original mutant.

Comment: This strain was originally described as respiratory deficient, unable to grow on acetate in the dark, but was not analyzed in detail because Wiseman was unable to obtain homoplasmic stock with a consistent phenotype. Subsequently the original strain acquired what appears to be a secondary nuclear mutation. At last check, the strain still showed a dark-dier phenotype.
