Genome conservation on L. johnsonii NCC533 microarrays. Scatter plot diagram of hybridization profiles for L. taiwanensis BL263 (y axis) versus L. gasseri ATCC 33323^T (x axis). The axis values represent the hybridization signal ratios expressed in a log₂ scale. For each gene, data points were colour-coded according to the hybridization profile of a third strain, L johnsonii ATCC 33200^T. Gene conservation colour was obtained from the signal ratio for each gene in log₂ scale. It ranged from black (presence in ATCC 32200^T of a homologous gene with respect to the reference strain NCC533) to white (absence of a gene). For instance, a white circle in the top left corner of the plot represents a gene present in BL263 and absent in both ATCC 33323^T and ATCC 32200^T.
