Venn diagram showing the occurrence of chloroplast RNA editing sites in Amborella trichopoda, Arabidopsis thaliana and Cucumis sativus. Editing position numbering refers to Amborella for shared sites. Underlining indicates RNA editing sites in Cucumis predicted and confirmed in the course of this study to extend the cucumber cp editome reported previously [32]. Highlighted in bold are sites ndhBeU467PL and ndhDeU878SL previously shown to be affected by editing factor CRR28 [37] and accDeU923SL, corresponding to Arabidopsis thaliana accDeU794SL, shown to be affected by editing factor RARE1 [39]
