(A) The physical arrangement of four rRNA-related motifs: rRNA processing element (mRRPE), polymerase A and C (PAC), mRRSE3, and mRRSE10. The 39 promoters containing all four sites or the motif triplet consisting of mRRPE, PAC, and either mRRSE3 or mRRSE10 are displayed. Each promoter is represented by a line and each circle represents a single copy of each motif. The distance of each motif in b.p. from the translational start site is displayed by the axis at the bottom of the figure. (B) Combinogram of the rRNA motif cassette during sporulation. The middle section of the Combinogram depicts the motif composition of each gene set. Each vertical column represents a single gene set. A black square indicates that the particular motif is present in the promoters of all the genes in that set. A white square indicates that none of the genes in the set contain the particular motif. The top and bottom sections of the Combinogram are as described in the legend for Figure 2B. All the genes in the genome containing each motif combination in their promoters were included in the Combinogram.
