Phylogram of group 3 WRKY domains from Arabidopsis (AtWRKY), cucumber (CsWRKY), poplar (PtWRKY) and soybean (GmWRKY). The phylogenetic tree was constructed using the neighbor-joining method as implemented in PHYLIP 3.2. Numbers on internal nodes are the percentage bootstrap support values (1000 re-sampling); only values exceeding 50% are shown. The most primitive Giardia lamblia WRKY C-terminal domain (GlWRKY1C) was used as an outgroup. The letters T and S indicate nodes where tandem duplication and recent segmental duplication events have occurred, respectively. * indicates the AtWRKY associated with the gene duplication events.
