Identification of a Rhizobium leguminosarum gene homologous to nodT but located outside the symbiotic plasmid.
An open reading frame (ORF471), homologous to nodT from Rhizobium leguminosarum, has been found outside the symbiotic plasmid. The deduced amino-acid sequence indicates that the gene product is an outer membrane lipoprotein similar to the NodT proteins. This ORF seems to be widespread among R. leguminosarum bv. viciae strains and its presence in the genetic background of different strains may explain the lack of a nodulation-deficient phenotype found in such strains carrying a nod mutation.
