Abstract

PPR (pentatricopeptide repeat) genes form a large family particularly prevalent in higher plants and targeted to organelles. They are involved in many post-transcriptional processes such as splicing, editing, processing and translation. Current data suggest that PPR proteins are involved in targeting effectors to the correct sites on the correct transcripts but the molecular mechanisms for RNA binding and effector recruitment by PPR proteins are not understood yet.
