RNA editing in rpl16 in four Populus species. The mitochondrial rpl16 gene (417 bp) shows five editing sites at positions 108, 110, 214, 383 and 389 bp, which are conserved in the four Populus species investigated. Bars indicate edited bases, their height shows the editing extent in percent. Lines show the coverage at each base as long as it is 100 or below. The four Populus species are color-coded in both bars and lines.
