Plant Mitochondrial Genes, Cytochrome C Oxidase and Cytoplasmic Male Sterility

  • Malcolm J. Hawkesford
  • Christopher J. Leaver

Summary

In the mitochondrial genome of cytoplasmic male sterile plants multiple recombination events have created unique chimaeric genes. These may be expressed as variant polypeptides, in one specific case as a modified form of cytochrome c oxidase subunit 1 polypeptide, and in another as a novel polypeptide apparently associated with this same subunit. Models for the molecular basis of cytoplasmic male sterility are discussed in relation to function and biogenesis of cytochrome c oxidase.
