RNA editing in plants is essential, with many mutants impaired in editing of specific sites exhibiting strong deleterious phenotypes, even lethality. The majority of editing in plants occurs in mitochondrial and plastid transcripts, however, A-to-I editing also occurs in cytosolic tRNAs. Here we review recent findings concerning the cellular machineries involved in the different types of editing, recent analysis of the proposed functions for editing, and recent models for its appearance and retention in different plant lineages.
