The amino acid sequence of a plastid protein is developmentally regulated by RNA editing.

Abstract excerpt

RNA editing in plant organelles post-transcriptionally alters single nucleotides by C-to-U or U-to-C conversions at highly specific sites. Plant editing is generally viewed as a repair mechanism acting at the transcript level by restoring conserved amino acid residues. Here we report that an editing reaction within the ndhB transcript (encoding a plastid NAD(P)H dehydrogenase subunit) is strictly dependent on...
