Figure 4.

Genomic regions with significant differences in signal intensity in the examined Ectocarpus strains. The graphs display the log2-ratio between sample and reference strain (1) for each probe. A log2-ratio of 0 means that there was no difference between the examined strains. Red dots represent probes in regions with significant differences between the test and the reference strain (1), blue dots the surrounding probes (if present). The grey dotted line indicates the mean log2-ratio over the highlighted area; the corresponding fold-change is given followed by an "x". E. fasciculatus (strain 5) was not included in this analysis (Sctg = supercontig, EsV = Ectocarpus siliculosus virus).
