Figure 3

Principal component analysis of the complete 46 taxa data set. The two first axes of the multidimensional space are shown, they account together for 48% of the data. The principal component analysis demonstrates that the majority of the sequences have a homogeneous amino acid composition. Nevertheless, there are also several outliers most of them expectedly associated with distant outgroup species; more precisely there are two red algae, several chlorophytes, but also three streptophyte algae (Mesostigma, Klebsormidium and Closterium) and the embryophyte Huperzia.
