We identified two DYW subclass pentatricopeptide repeat (PPR) proteins, PpPPR_78 and PpPPR_79, as RNA editing factors in the moss Physcomitrella patens. Disruption of each gene by homologous recombination revealed that PpPPR_78 was involved in RNA editing at the rps14 (rps14-C137) and cox1 (cox1-C755) sites and PpPPR_79 at the nad5-1 (nad5-C598) site in the mitochondrial transcripts. RNA editing defects did not affect transcript patterns of the target genes. Thus, DYW subclass PPR proteins seem to be site-specific trans-acting factors for RNA editing.
