Principal component analysis (PCA) plot of the KOG distributions of the four prymnesiophytes in this study and of other protistan genomes and transcriptomes.

<p>The same dataset from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097801#pone-0097801-g005" target="_blank">Fig. 5</a> was used to generate this figure. The color scheme and species identification by numbering also correspond to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0097801#pone-0097801-g005" target="_blank">Fig. 5</a>. Explained cumulative variability for this plot was 54.2%, with eigenvalues of 8.5 (F1) and 4.5 (F2). Only top variables for F1 and F2 are plotted in the graph.
