Phylogenetic tree of 101 flax WRKY proteins and 67 Arabidopsis WRKY proteins. The phylogenetic tree was constructed using MEGA 5.0 based on the neighbor-joining method, with bootstrap testing performed for 1000 replicates. The seven groups/subgroups are shown in different colors and unclassified proteins are indicated by red circles
