Hurley Shepherd in Boynton-Gillham laboratory, Duke University

Phenotype: requires acetate; antibiotic resistant (spectinomycin)

The ac-u-i-2-25 mutant is deficient in chloroplast ATP synthase activity. The original mutant strain studied by Shepherd also lacked chlorophyll protein complex CP I and was originally thought to have a primary defect in this protein. Subsequent analysis by Bennoun (see Woessner et al., 1984) showed that this mutant has a leaky ATP synthase-deficient phenotype in dim light.

This information was published in a footnote to a table in Woessner et al. (1984); however this mutant was not included in the complementation/recombination matrix in that paper.

This mutation is closely linked genetically to Bennoun’s CP I deficient mutant C1.

See CC-104 for additional information on the spr-u-1-27-3 mutant.
