Table 2 nod gene expression in S. meliloti GR4, the tep1 mutant and a nodC mutant.

From: The tep1 gene of Sinorhizobium meliloti coding for a putative transmembrane efflux protein and N-acetyl glucosamine affect nod gene expression and nodulation of alfalfa plants

Strain β-galactosidase activity (Miller U)
GR4 (wt) 387 ± 48
GR4T1 (tep1) 144 ± 24
GR4C5 (nodC) 137 ± 34
  1. β-galactosidase activity of the nodC::lacZ fusion was measured after bacteria had been incubated with 5 μM luteolin. Mean values and standard errors (95% confidence) were calculated from three independent experiments.
