Expression of BBRE Genes and BL-Responsive Genes Is Altered in BAM8-OX and bam7bam8.
(A) The relative occurrence of significantly (P < 0.1) deregulated genes carrying a BBRE in their 500-bp promoters. Relative occurrence is defined as the ratio of observed changes to those expected by chance, given the total number of deregulated genes (see Methods). More BBRE genes than expected are highly upregulated in BAM8-OX (red), and very downregulated in bam7bam8 (blue), relative to other genotypes. The bar patterns indicate the fold-change categories, as indicated. Genotypes are as follows: B8OX, BAM8-OX; b7b8, bam7bam8; b8, bam8; WT, wild type. Pale bars indicate that, between the compared genotypes, fewer than 50 genes in total are deregulated to the extent indicated. The numbers of genes are given in Supplemental Table 1 online.
(B) Expression of BBRE genes in BAM8-OX and bam7bam8 relative to the wild type, showing inverse regulation. Blue circles indicate genes that are changed in either genotype (P < 0.1); red crosses indicate genes that are changed in both genotypes; gray circles indicate genes that are unchanged.
(C) Relative occurrence of BL-repressed genes among significantly deregulated genes, annotated as in (A).
(D) Relative occurrence of BL-induced genes among significantly deregulated genes, annotated as in (A). The numbers of genes for (C) and (D) are given in Supplemental Table 3 online.
