Abstract: RNA editing has been observed in the chloroplasts of all land plants analyzed to date with the exception of liverworts. In this study, we analyzed the 1 514 chloroplast RNA editing sites from non-vascular plants (hornwort and moss) and vascular land plants (fern and eudicot) in features of the probability of amino acid transition, the probability of codon transition, the probability of position of editing site occurring in the codon, the probability of the occurrence of four bases at the minus 1 position near the RNA editing site, and the probability of the occurrence of four bases at the plus 1 position near the RNA editing site. We found that the codon transition of chloroplast RNA editing eudicot is significantly different from that of other plant groups.
