title: Mitochondrial plasmid-like molecules in fertile and male sterileVicia faba L.
abstract: Biochemical analysis and electron microscopy showed that mitochondria of both the fertile and the male sterile 350 and 447 cytoplasms ofVicia faba. L. contain two small supercoiled DNA molecules of mean length of 1 700 and 1 420 base pairs in addition to the main mitochondrial DNA of high molecular weight. By agarose gel electrophoresis, the male sterile cytoplasm 350 is distinguished from the fertile cytoplasm and from the male sterile cytoplasm 447 by the presence of an additional supercoiled DNA molecule of approximately 1 540 bp.
