Figure 2.

The neighbor-joining tree and motif compositions of the 24 VHA-H genes from 12 species of plants and yeast (Saccharomyces cerevisiae, ScVHA-H), which was used as outgroup. The green and blue backgrounds on the tree indicate the clades of dicots and monocots, respectively. Bootstrap values based on 1,000 replicate analysis and the values of the posterior probability based on Bayesian analysis separated by forward slashes are given on the branches. The bar on the bottom left indicates 0.05 base differences per amino acid position. A total of 15 motifs represented by color bars are revealed on the 24 VHA-H genes. The ruler on the bottom right displays the location information of each motif on the amino acid chain.
