Phylogenetic relationship of HD-ZIP III subfamily from eight plant species.

<p>Enlarged view of the phylogeny of HD-ZIP III members from <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031149#pone-0031149-g001" target="_blank">Figure 1A</a>. Numbers at each branch indicate bootstrap values and only values higher than 50% are shown. Scale bar corresponds to the estimated number of amino acid substitutions per site. Filled circles represent HD-ZIP proteins from different plant species. Colors correspond to plant taxa as indicated in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031149#pone-0031149-g001" target="_blank">Figure 1</a>.
