Figure 5.

Venn diagram indicating the number of conserved sequences in tested strains of E. siliculosus. A sequence was considered to be conserved when all four probes corresponding to this sequence exhibited an absolute log2-ratio with the control < 1. The first number indicates the total count of ESTs derived sequences (singletons and contigs) conserved between the strains, and the percentage of these sequences represented only by probes in the CDS region is given below. The number in the center of the graph, for example, indicates that 7,497 sequences are conserved between strain 1, 2, 3, and 4, while the number in the blue circle above shows that 16,542 sequences were conserved between strain 1 and strain 2. Please note that strain 1 is the basis of all comparisons, as only genes that are present in this strain are represented on the array. Strain 5 was not included in this analysis due to the bias introduced by the normalization procedure.
