Figure 1From: Molecular cloning and expression analysis of WRKY transcription factor genes in Salvia miltiorrhiza Phylogenetic tree of the WRKY domain from SmWRKYs (red), AtWRKYs (blue). PpWRKYs (dark green), FLYWCH (pink) and GCMa (light green). Groups/subgroups are shown; ‘N’ and ‘C’ indicate the N-terminal and C-terminal WRKY domain of a specific WRKY protein.Back to article page
