Figure 5.

Expression levels of target genes bound by Su(var)3-9, HP1, and HP1c. Histograms are shown of relative gene expression levels of single-copy genes. Expression levels are calculated as normalized log2-transformed spot intensities after hybridization of labeled mRNA from untreated Kc cells to microarrays (average of three experiments; see Materials and Methods). (A) Su(var)3-9 target genes (gray) compared with an equal number of nontarget genes (black). (B) HP1 target genes (gray) compared with an equal number of nontarget genes (black). (C) Genes that are targets of both Su(var)3-9 and HP1 (dark gray) compared with genes that bind only Su(var)3-9 (light gray). (D) HP1c target genes (gray) compared with an equal number of nontarget genes (black). (E) Pericentric (white) compared with nonpericentric (gray) Su(var)3-9 target genes. Pericentric genes include all genes on chromosome 4. (F) Pericentric (white) compared with nonpericentric (gray) HP1 target genes.
