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

Table 4 tep1 gene expression in S. meliloti GR4 under different growth conditions.

Growth medium	β-galactosidase activity (Miller U)
TY	1523 ± 140
MM	449 ± 16
MM+GA	652 ± 33
MM+NAGA	792 ± 29

Expression of a tep1::lacZ fusion was measured in S. meliloti GR4 harbouring pMTR4 in TY medium, minimal medium (MM), and MM supplemented with either 5 mM glucosamine (GA) or 5 mM N-acetyl glucosamine (NAGA). Mean values and standard errors (95% confidence) were calculated from three independent experiments.
