Figure 3.

Unrooted phylogenetic tree representing relationships among WRKY domains of cucumber and Arabidopsis. The amino acid sequences of the WRKY domain of all CsWRKY and AtWRKY proteins were aligned with Clustal W and the phylogenetic tree was constructed using the neighbor-joining method in MEGA 4.0. Group 1 proteins with the suffix 'N' or 'C' indicates the N-terminal WRKY domains or the C-terminal WRKY domains. The red arcs indicate different groups (or subgroups) of WRKY domains. Diamonds represent orthologs from cucumber (blue) and Arabidopsis (red).
