Phylogenetic tree of VvWRKY s. The unrooted phylogenetic tree of WRKY domains was constructed with MEGA5.1 program with the neighbor-joining method. The numbers beside the branches represent bootstrap values based on 1000 replications. The name of groups (I, II, III and IV) and subgroup (a–e) were shown at the outside of the circle. The WRKY named with suffix -N or -C indicated the N-terminal WRKY domain (NTWD) or the C-terminal WRKY domain (CTWD) in one VvWRKY with two WRKY domains. AtWRKYs were used as reference to categorize VvWRKYs.
