Mitochondrial genes are subject to evolutionarily frequent horizontal transfer between distantly related flowering plants. A phylogeny of 280 angiosperms is marked according to the presence (red) or absence (blue) of rps 2 (a) and rps 11 (b) in mitochondrial DNA. Blue and red bullets mark inferred losses and regains, respectively, of these genes. Names of taxa with gene regain are shown in red lettering, selected taxa with gene loss are in blue. There must be mechanisms for the delivery of DNA between unrelated plants. This is unusual for multicellular organisms. Nature 424, 197 -201, 2003.
