Sinorhizobium meliloti was studied by proteomic analysis to investigate the contribution made by plasmid-encoded functions on the intracellular regulation of this bacterium. Protein profiles of strain 2011 were compared with those from its mutant strains which were either cured of their pRme2011a (also called pSyma) plasmid (strain 818), or contained an extensive deletion of this plasmid (strain SmA146). Plasmid pSyma contains the nodulation and nitrogen fixation genes and is 1.4 Mbp with an estimated coding potential of 1,400 proteins. However, under the growth conditions used we could detect 60 differences between the parent strain and its pSyma-cured derivative, strain 818. While the majo..View full abstract
