Abstract

RNA editing in plant mitochondria and chloroplasts alters mRNA sequences to code for different proteins than the DNA. Most of these C-to-U transitions occur in open reading frames, but a few are observed in intron sequences. Influences of the nuclear genome on editing patterns suggest that cytoplasmic factors participate in this process.
