Architecture of conserved protein motifs in SmWRKYs and AtWRKYs. A: Architecture of conserved protein motifs in SmWRKYs and AtWRKYs from different groups (or subgroups). Motifs represented with boxes are predicted using MEME. The number in boxes (1–20) represents motif 1–motif 20, respectively. Box size indicates the length of motifs; B: Sequence logo of eleven conserved motifs, including motif 7, motif 9–motif 12, motif 14–motif 18 and motif 20. The logos were created on the WebLogo server (http://weblogo.berkeley.edu/logo.cgi). Bits represent the conservation of sequence at a position.
