mitochondrial plasmid specifically associated with male sterility and its relation with other mitochondrial plasmids in Vicia faba L

Small supercoiled DNA molecules of Vicia faba were cloned and characterized by restriction mapping and molecular hybridization. The 1700 bp S plasmid has been found to be specifically associated with the male sterile cytoplasms and exhibited large homologies with the other 1700 bp F plasmid as shown...

Description
Summary:Small supercoiled DNA molecules of Vicia faba were cloned and characterized by restriction mapping and molecular hybridization. The 1700 bp S plasmid has been found to be specifically associated with the male sterile cytoplasms and exhibited large homologies with the other 1700 bp F plasmid as shown by molecular cross hybridization. In one line bearing the male sterile 350 cytoplasma, a deleted mitochondrial plasmid of 1540 bp was observed and this plasmid derives from the 1700 bp S plasmid. The results indicate therefore that three of the four plasmids analysed are closely related between each other.
