Abstract

This article reviews the investigations on the mitochondrial genomes of yeast carried out in the author's laboratory during a quarter of a century (to be precise between 1966 and 1992). Our studies dealt with the structural basis for the cytoplasmic petite mutation, the replication, the transcription and the recombination of the mitochondrial genome, a genome which is dispensable and which comprises abundant non-coding sequences. This work led to some general conclusions on the nuclear genome of eukaryotes. Some recent results in apparent contradiction with our conclusions on ori sequences will also be briefly discussed.
