Figure 3

Scatter plot showing log2 transformed ratios obtained from direct cDNA: cDNA hybridization and indirect comparison using genomic DNA as a reference. cDNA: cDNA hybridization was carried out using two RNA samples isolated from S. coelicolor mycelia obtained from liquid culture at early (Sample 1) and late (Sample 2) growth stages. For the indirect comparison using genomic DNA, each of the two samples was hybridized with genomic DNA.
