Schematics depicting integration of plasmids into the S. meliloti genome to generate transcriptional fusions. Integration of (A) pJC445, (B) pJC446, (C) pJC447, and (D) pJC455 resulted in fusions of the uidA reporter to promoter regions upstream of araA (SMb20895), tauA (SMb21526), rhaR (SMc02323), and melA (SMb21648), respectively. The sizes of the regions that enabled homologous recombination are shown below each plasmid. gbpR, tauR, rhaR, and agpT represent potential or confirmed regulators of genes involved in arabinose (ara), taurine (tau), rhamnose (rha), or melibiose/alpha-galactoside (mel/agp) metabolism. White pentagonal blocks indicate genes without assigned function.
