Research Abstract

In chloroplasts and mitochondria, RNA editing frequently occurs in many transcripts of most terrestrial plants. RNA editing is an enigmatic phenomenon in which specific cytidines (C) in the transcripts are changed to uridines (U). Since C-to-U RNA editing was discoveredin plant organelles 20 years ago, the RNA editing enzyme or factors remain to be identified. In this study, we have identified several novel RNA editing factors using a model plant, Physcomitrella patens.
