tolC mutant of Sinorhizobium meliloti strain CXM1-188 fails to establish effective symbiosis with alfalfa


The TolC mutant Tr63 of Sinorhizobium meliloti was generated by random Tn5 mutagenesis in the effective strain CXM1-188. The mutant did not produce fluorescent halos in UV light on the LB medium containing Calcofluor white, which suggests that modification occurred in the production of exopolysaccharide EPS1. Mutant Tr63 also manifested nonmucoidness both… (More)
