Figure 2From: Molecular cloning and expression analysis of WRKY transcription factor genes in Salvia miltiorrhiza Multiple sequence alignment of the WRKY domain from SmWRKYs. Red box indicates conserved WRKY amino acid signature and zinc-finger motif; Black box indicates conserved amino acids. ‘N’ and ‘C’ indicate the N-terminal and C-terminal WRKY domain of a specific WRKY protein.Back to article page
