Hybridization and blast atlas. The atlas illustrates the hybridization pattern of MG1655 probes for the two control strains, MG1655 and EDL933, and the four Symbioflor2 isolates. Also, it illustrates the MG1655 genes' BLAST score for presence in the EDL933 strain. The circles from outermost to innermost are: Blast score between 0 for absent and 1 for present MG1655 genes in the EDL933 strain, log2 transformed hybridization intensities for EDL933 and MG1655 samples, log2 ratio of EDL933/MG1655 samples, location of predicted coding sequences (CDS), log2 hybridization intensities for the four Symbioflor2 isolates G5, G4/9, G3/10, G1/2, probe coverage.
