An RNA recognition motif-containing protein is required for plastid RNA editing in Arabidopsis and maize
Abstract
Transcripts in plant organelles are altered by conversion of cytidines to uridines in a process termed RNA editing. Members of two protein families have been identified in the plant editosome, but its complete composition is unknown. Now a unique protein that contains an RNA recognition motif has been found to be essential for editing of multiple plastid transcripts in both Arabidopsis and maize. Phylogenetic analysis indicates that this protein belongs to a sub-family of RNA recognition-motif proteins predominantly predicted to be targeted to organelles and that are thus likely to play roles in organelle RNA metabolism.
