They all do. Plant mitochondria are in fact likely to be a highly
useful resource in the development of mitochondrial gene therapy,
because all plants yet examined have retained the standard genetic
code in their mitochondria, thus allowing gene transfer to the
nucleus to continue (albeit very rarely, since the encoded proteins
are so hard to re-import). Several examples are now known of genes
encoded in our mitochondrial DNA which are nuclear in one or another
plant; the study of how the encoded proteins are got back in will
probably be highly illuminating.
