From: Complete gene expression profiling of Saccharopolyspora erythraea using GeneChip DNA microarrays
Regional organization of gene expression. Visualization of the LAP algorithm results on the two chromosome's strands independently analysed. Panel A) Comparison between the transcriptional profiling of all the 6494 S. erythraea genes in Phase A versus Phase B. Panel B) Comparison between the transcriptional profiling of all the 6494 S. erythraea genes in Phase B versus Phase C. A q value of 0.01 and a fold change of 0.5 were chosen as filtering parameters. The transcriptionally up-modulated regions are shown in RED while the down-modulated are in GREEN. The OriC is indicated as O and the resolution of the chromosome is 1 Mb. The core region is evidenced in blue and the non-core region in orange; the clusters involved in the secondary metabolism and discussed in the text are positionally outlined by arrows in figure A.
