Figure 1

Phylogenetic tree of GRAS proteins among Arabidopsis , Brachypodium distachyon , rice, soybean, Physcomitrella patens , and Selaginella moellendorffii . A) The major clusters of orthologous genes are shown in different colors: group I = purple, group II = dark blue, group III = yellow, group IV = light green, group V = pink, group VI = dark green, and group VII = light blue. The scale bar corresponds to 0.1 estimated amino acid substitutions per site; B) Genes belonging to the different groups are shown. Among them, the deduced DELLA proteins are indicated by a filled red square, and genes with similar functions clustered together are indicated by filled green circles.
