In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother. By contrast, paternal transmission is observed only occasionally, and the mechanisms behind this phenomenon have remained largely unknown. In a study published in Nature Plants, researchers established a genetic screening system in tobacco plants that allowed them to detect paternal mitochondrial inheritance.
