(A) Joined phylogenetic tree of the rice and Arabidopsis Dof gene families. The unrooted tree was inferred by the neighbor-joining method after the alignment of the Dof domain amino acid sequences of the 66 Arabidopsis and rice genes listed in Table 1 and 2 respectively. Arabidopsis (normal case) and rice genes (italics) are indicated at the end of solid and dotted branches, respectively. Bootstrapping values are indicated as percentages (when >50 %) along the branches. The resulting major clusters of orthologous genes (MCOG) are shown in different colors: Aa = orange, Bb = blue, Cc = red and Dd = green. Subscript numbers indicate the defined subgroups. The scale bar corresponds to 0.1 estimated amino acid substitution per site. Phylogenetic trees of rice (B) and Arabidopsis (C) Dof gene families. The unrooted trees were inferred by the neighbor-joining method after the alignment of the Dof domain amino acid sequences of the 30 rice and 36 Arabidopsis genes listed in Tables 1 and 2, respectively. The resulting groups are shown in different colors: A or a = orange, B or b = blue, C or c = red and D or d = green. Subscript numbers indicate the defined subgroups. The scale bar corresponds to 0.05 estimated amino acid substitutions per site. Genes belonging to the different groups are listed in Table 1 and 2.
