The nucleotide sequence of the repeat unit of the mitochondrial genome of a spontaneous petite mutant of S. cerevisiae is reported. The sequence provides direct information on the AT-spacers and GC-clusters of the mitochondrial genome of yeast.
We have reinvestigated the linkage orientation of repeating units in mtDNAs of yeast p-petite mutants containing an inverted duplication. All five petite mtDNAs studied contain a continuous segment of wild-type mONA, part of which is duplicated and present in inverted form in the repeat. We show by
Sequence analysis was used to define the repeat unit that constitutes the mitochondrial genome of a petite (rho-) mutant of the yeast Saccharomyces cerevisiae. This mutant has retained and amplified in tandem a 2,547 bp segment encompassing the second exon of the oxi3 gene excised from wild-type mtD
