Fig. 1From: Genome-wide identification and expression analysis of the WRKY transcription factor family in flax (Linum usitatissimum L.)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 circlesBack to article page
