Regenerating good sense: RNA editing and trans splicing in plant mitochondria.
The protein products of plant mitochondrial genes cannot be predicted accurately from genomic sequences, since RNA editing modifies almost all mRNA sequences post-transcriptionally. Furthermore, RNA editing alters leader, trailer and intron sequences, and may be required for processing of these sequences. For several plant mitochondrial transcripts, processing includes trans splicing, which connects exons scattered throughout the genome. The mature transcripts are assembled via split group II intron sequences.
