Table 1 Expression of transcriptional fusions to lacZ in S. meliloti GR4 and GR4T1.

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

   β-galactosidase activity (Miller U)
   pGD499 (npt::lacZ) pRmM57 (nodC::lacZ)
- luteolin GR4 465 ± 38 47 ± 12
  GR4T1 435 ± 35 45 ± 14
+ luteolin GR4 418 ± 34 777 ± 26
  GR4T1 398 ± 48 260 ± 45
  1. β-galactosidase activity of the npt::lacZ and nodC::lacZ fusions were measured in the absence and presence of luteolin (5 μM). Mean values and standard errors (95% confidence) were calculated from three independent experiments.
