We report an analysis of the sequences used in the excision of the mitochondrial genomes of 22 spontaneous and ten ethidium bromide (EtBr)-induced Saccharomyces cerevisiae petite mutants. In all cases, excision sequences were found to be perfect direct repeats, often flanked on one or both sides by regions of patchy homology. Sequences used in the excision of the genomes of spontaneous petites were always located in the AT spacers and GC clusters of intergenic regions of the genome; the GC clusters corresponded to ori and oris sequences, namely to canonical and surrogate origins of DNA replication, respectively. In the case of the ethidium bromide-induced petites, excision sequences were found not only in intergenic sequences, but also in the introns and exons of mitochondrial genes.
