Transcriptional activity of rhizobial promoters in the R. leguminosarum bv. trifolii wild-type Rt24.2 and the rosR mutant Rt2472 strains. a β-galactosidase activity of the transcriptional fusions of representative genes encoding regulatory proteins, components of the transport systems, cell-surface components and enzymes for synthesis of polysaccharides; b β-glucuronidase activity of the transcriptional fusions of motility genes. The log₂ fold changes for the individual genes obtained in the RNA-Seq analysis are given below the diagrams. Genes, for which differences in transcription levels between these backgrounds were not found, are marked with the symbol “-”
