Figure 4

Microarray analysis showing changes in global control of cell-cycle. Visualization by dChip of 404 S. erythraea NRRL2338 and of 577 S. erythraea Px differentially expressed genes, selected by a q-value < = 0,001, and determining a time course gene expression profiling and a hierarchical clustering of the samples (Red = up-regulation; Green = down-regulation); on the right side of the figure, two columns respectively show the functional classification of the DEGs whose transcription profile is visualized and their positional distribution in the core (dark blue) and non core region (light blue) of the genome.
