摘要：

Cytoplasmic male sterility, conditioned by some maternally inherited plant mitochondrial genomes, is the most expedient method to produce uniform populations of pollen-sterile plants on a commercial scale. Plant mitochondrial genomes are not currently amenable to genetic transformation, but genetic manipulation of the plastid genome allows engineering of maternally inherited traits in some species. A recent study has shown that the Acinetobacter beta-ketothiolase gene, expressed in the Nicotiana tabacum plastid, conditions maternally inherited male sterility, laying the groundwork for new approaches to control pollen fertility in crop plants.
