| prevalence of psmesm11a-like plasmids in indigenous sinorhizobium meliloti strains isolated in the course of a field release experiment with genetically modified s. meliloti strains. | plasmid psmesm11a, residing in the indigenous sinorhizobium meliloti strain sm11 originating from a field in strassmoos (bavaria, germany), was analysed previously at the genomic level. thirty-seven indigenous s. meliloti strains, originating from two different locations in germany, were screened for genes identified previously on psmesm11a. seven of these strains harbour accessory plasmids that are very similar to psmesm11a. the identified psmesm11a-like plasmids are c. 130-150 kb in size and p ... | 2008 | 18034835 |
