Motifs reported by MUSA [] and Promzea [] for 49 promoter sequences of apical growth selective genes. Motifs detected by MUSA are ranked by p-value, highlighting correspondence to cis-elements summarized in PLACE database . The quorum value shows the number of query sequences in which a certain motif stands. The sequence consensus for each motif detected by Promzea was compared to known plant promoter database by STAMP , and the results were ranked by p-value. Only the most significant result is shown.
