Figure 2From: Chasing the hare - Evaluating the phylogenetic utility of a nuclear single copy gene region at and below species level within the species rich group Peperomia (Piperaceae)Characteristics of utilized markers. Portions of constant (green), variable (red) and parsimony informative characters (dashed) for coding and non-coding parts of all markers used in this study. Chloroplast markers suggested by Shaw et al. [19, 20] for species level were combined into the longer regions that we co-amplified with single primer pairs. Full sampling comprises 62 accessions. Reduced sampling is a dataset that contains a sub-sampling of 26 selected accessions from the full sampling. The percentage of variability of the chloroplast markers is very similar between regions and among coding and non-coding portions at the taxonomic level in this study. In contrast, the nuclear gene has highly variable introns, which yields a total variability that is two to three times greater than any of the chloroplast markers.Back to article page
