Figure 6.

Conserved motifs in modules 6 and 7. (a,b) The motifs most frequently found among genes in modules 6 (a) and 7 (b) are shown. The frequency of each nucleotide at each position is depicted on the y-axis, with the nucleotide position within the consensus sequence depicted on the x-axis. The motif in (a) was contained within 29 of 35 genes in module 6; the motif in (b) was contained in 18 of 54 genes in module 7. Significance level of adherence to the consensus sequence was at least P = 2.68 × 10^-4 for (a) and P = 9.32 × 10^-6 for (b).
