Figure 1. Phylogenetic tree of deduced amino acid sequences of class C MADS-box genes. The phylogenetic tree was constructed by the neighbor-joining method using deduced amino acid sequences. The numbers at the nodes show bootstrap values after 1,000 replicates. The deduced amino acid sequences of the entire coding region were obtained from the DDBJ database: WAG-1 (AB084577), WAG-2 (AB465688), WM2 (AM502863), WM29A (AM502898), WM29B (AM502899), AGL39 (DQ512355) from wheat; HvAG1 (AF486648) and HvAG2 (AF486649) from barley; OsMADS3 (L37528) and OsMADS58 (AB232157) from rice; ZMM2 (X81200) and ZAG1 (L18924) from maize; AG (X53579) from Arabidopsis; and PLE (S53900) from Antirrhinum.
