Fig. 7. Distribution of the ZA-rII′ fusion over the PUR5 and PHO5 genomic regions. (A) Binding of ZA-rII′ at PUR5 gene under repressed conditions. (B) Distribution of ZA-rII′ at the PUR5 gene. (C) Same experiment as in (A) but the PHO5 genomic region was analyzed. (D) Distribution of ZA-rII′ at the PHO5 genomic region. All PCRs contain ARN1 primers used as an internal control to normalize signals for each lane.
