Most of higher plant species are hermaphroditic and male-sterility is often considered as an accident of development. In fact among the multiple possible causes of male-sterility, the most frequently met in nature is cytoplasmic male-sterility (cms) which is a maternally inherited trait playing an active role in the evolution of gynodioecious species. Recent molecular studies have shown that this trait is determined by additional genes created in plant mitochondrial genomes due to their high recombinogenic activity. The physiological mechanisms by which the products of these genes interfere with the formation of male gametophytes are still the subject of intense research.
