CC-368 ac-u-c-1-20 mt+

Locus: atpB, chloroplast genome

Source: Isolated by Hurley Shepherd in the Boynton/Gillham laboratory, obtained by mutagenesis with 5-fluorodeoxyuridine

Comment: This is a deletion mutation in the atpB gene. CC-368 is easy to score as a clean acetate-requiring strain. Another deletion mutant, CC-373 ac-u-c-2-21, is more frequently used as a recipient for atpB transformation of the chloroplast, however.
