Schematic representation of B. breve UCC2003 gene clusters upregulated during growth of PGOS as sole carbohydrate source. The lengths of the arrows are proportional to the length of the predicted ORF and the gene locus name, which is indicative of its putative function, is indicated within the arrow. The bent arrows indicate the galC and galA promoters; the lollipop sign designates putative rho-independent terminator region. β-Galactosidase-encoding genes are indicated by blue shading, while genes encoding proteins with transport functions are shaded in yellow. Putative or proven genes encoding LacI-type transcriptional regulators are indicated by red shading.
