Southern blot analysis of mtDNA molecules from the parental strains S. cerevisiae CCY 21-4-96 and S. paradoxus CBS 2908 and hybrid 4-R3 (72 K). HinfI restriction analysis of mtDNAs is at the left, while the autoradiograms showing hybridizations with the cox3, rns, and trnM probes are to the right. The cox3 and rns probes were 32P-labeled PCR products of the corresponding genes. The trnM probe was an oligonucleotide of which the 5′ end was labeled with γ32P-ATP. The arrows on the trnM picture show the S. cerevisiae band that is present in the 4-R3 (72 K) hybrid.
