Organelles, such as mitochondria and chloroplasts, are derived from endosymbionts. Gene transfer events from organelles to the nucleus have occurred over evolutionary time. In the case that a transferred gene in the nucleus needs to go back to the original organelle, it must obtain targeting information for sorting its protein to that organelle. Here, we reveal that the genes for the ribosomal proteins L2 and S4 in the Arabidopsis thaliana mitochondrial (mt) genome contain information for protein targeting into the mitochondria. Similarly, the genes for the ribosomal proteins L2 and S19 in the Oryza sativa mt genome contain information for protein targeting into mitochondria. These results suggest that targeting information already existed in each gene in the plant mt genome before the transfer event to the nucleus occurred. We provide new insights into the timing of the appearance of targeting signals in evolution.
