Arabidopsis WRKY group III transcription factor family. RT-qPCR time course study of WRKY group IIIa (A) and IIIb (B) gene expression in wild-type leaves treated with 5 mM salicylic acid (SA). Phylogenetic relationships between these WRKY group III transcription factors are indicated below the expression data. Protein alignment was carried out with ClustalX and the trees were constructed by Neighbor–Joining distance analysis. Line lengths indicate the relative distances between nodes. (C) Protein sequence alignment of WRKY54 and WRKY70. The WRKY domain is underlined, with the consensus motif WRKYGQK and the zinc-finger motif C2-HC in boxes. Symbols on the consensus lines represent amino acid positions: ‘*’ fully conserved, ‘:’ one of the strong amino acids group is conserved, and ’.’ one of the weak amino acid groups is conserved.
