MEME de novo motif discovery within GBS. A. Motifs for transcription factor binding in the 683 GBS that contain a GRE-like sequence. B. Motifs for transcription factor binding in the 500 GBS without a GRE. Analysis was performed within a 200 bp-frame containing the GBS-centre in the middle. The frequency of identified motifs in the PC12-dataset is indicated as well as transcription factors of which the known binding motif most significantly matches the identified motif. Only motifs with an E-value < 1E-5 are depicted.
