5-Methylcytosine mapping of RTBV [dps] promoter from position −229 to +114 in line R1. Completely (m) or partially (p) methylated cytosines are indicated. hem, hemizygous; hom, homozygous. The gap around +70 indicates a region for which no clear sequencing data could be obtained. Sites that were also analyzed by restriction analysis and promoter elements that bind proteins under our experimental conditions are indicated [VBE (40); AE, activator element (41); dps1 and 2, downstream promoter sequence (35, 61)].
