Pflanzliche RNA-Editoren in diversen genetischen Systemen

Abstract Given their endosymbiotic origin, plant mitochondria and plastids possess their own genomes. Within these genomes, pyrimidine transition mutations are enriched. They are fixed on RNA level through nuclear-encoded Pentatricopeptide Repeat (PPR) editing factors. We successfully expressed selected plant organellar PPR editors in diverse genetic contexts to investigate their applicability, specificity and mode of operation.
