Occurrence of silent RNA editing in chloroplasts: its species specificity and the influence of environmental and developmental conditions

Abstract

We have identified three new C-to-U RNA editing sites, one in atpF and two in atpA transcripts from tobacco chloroplasts. Two of them lead to amino acid substitutions to restore the conserved amino acid found in the corresponding genes of other plants. However, one editing site in the atpA transcript was found to take place partially at the third base of a serine codon (CUC_ to CUU_), thus not leading to an amino acid substitution. This is the first report of silent editing in chloroplasts. The extent of silent editing depends on plastid stage and light conditions, while editing as another site (found 4 nt upstream from the silent editing site) takes place constitutively even in non-photosynthetic cultured cells and bleached white seedlings grown in the presence of spectinomycin and streptomycin. In pea and spinach, despite a conservation in sequence, no editing at the site corresponding to the silent site in tobacco was found. This observation suggests that the silent editing detected in this study is species-specific.
