Yao-Guang Liu and colleagues identify the molecular basis of male sterility in the Wild Abortive CMS (CMS-WA) system that has been widely used for hybrid rice breeding. They report that a new mitochondrial gene, WA532, confers male sterility because its protein product interacts with the mitochondrial protein COX11 and leads to cytoplasmic-nuclear incompatibility.
