Phylogenetic analysis of the WRKY transcription factors in rose, Arabidopsis, and other plant species. Complete alignments of the rose and Arabidopsis WRKY sequences, and the disease-resistance-related WRKY transcription factors from a variety of plant species, including cotton (Gossypium hirsutum), rice (Oryza sativa), oilseed rape (Brassica napus), grape (Vitis vinifera), tobacco (Nicotiana benthamiana), barley (Hordeum vulgare), and pepper (Capsicum annuum), were generated to construct a phylogenetic tree using the Neighbor-Joining method. The bootstrap values are indicated on the nodes of the branches. The WRKYs reported to be involved in plant disease resistance are marked in bold
