Photorepair of ultraviolet-induced petite mutational damage in Saccharomyces cerevisiae requires the product of the PHR1 gene.
A wild-type (phr+) diploid yeast strain showed photorepair of petite mutational damage, whereas a photoreactivation-deficient (phr1/phr1) diploid strain did not, indicating that the PHR1 gene product was required for mitochondrial photorepair.
