The W-Box Is the Predominant Motif within WRKY Binding Regions.

(A) to (C) Motif position probability graphs for WRKY18 (A), WRKY40 (B), and WRKY33 (C) established by CentriMo motif search (Bailey and Machanick, 2012). Indicated are the most frequent motif, its rate of occurrence, and the probability of this motif occurring at a given position relative to the binding peak summit (0) in the 500-bp binding regions. The included P value describes the significance for central enrichment.
