Unveiling the molecular arms race between two conflicting genomes in cytoplasmic male sterility?
Cytoplasmic male sterility can be thought of as the product of a genetic conflict between two genomes that have different modes of inheritance. Male sterilizing factors, generally encoded by chimeric mitochondrial genes, can be down-regulated by specific nuclear restorer genes. The recent cloning of a restorer gene in rice and its comparison with restorer genes cloned in petunia and radish could be regarded as the beginning of a general molecular scenario in this peculiar arms race.
