Symbiotic4
  • S. meliloti forms a symbiotic relationship with legumes from the genera Medicago, Melilotus and Trigonella, including the model legume Medicago truncatula. (wikipedia.org)
  • Because soil often contains a limited amount of nitrogen for plant use, the symbiotic relationship between S. meliloti and their legume hosts has agricultural applications. (wikipedia.org)
  • Creation and Characterization of a Genomically Hybrid Strain in the Nitrogen-Fixing Symbiotic Bacterium Sinorhizobium meliloti. (unifi.it)
  • Role and regulation of ACC deaminase gene in Sinorhizobium meliloti: is it a symbiotic, rhizospheric or endophytic gene? (unifi.it)
Strains1
  • Genomic comparative analysis of widely applied Sinorhizobium meliloti reference strains", устный доклад на сателлитом митинге по Геномике в рамках конференции. (arriam.ru)
10211
  • Five S. meliloti genomes have been sequenced to date: Rm1021, AK83, BL225C, Rm41, and SM11 with 1021 considered to be the wild type. (wikipedia.org)
Symbionts1
  • S. meliloti fix atmospheric nitrogen into ammonia for their legume symbionts, such as alfalfa. (wikipedia.org)
Alfalfa1
  • Polymorphism of rrsrrl sequence of ribosomal operons (intergenic sequence, ITS) was studied among 81 isolates of Sinorhizobium meliloti (AK001-AK210) derived from the collection of alfalfa nodulating bacteria of the Laboratory of genetics of ARRIAM, by using speciesspecific primers FGPS1490/ FGPL132VM. (unifi.it)
Rhizobia3
  • Leghemoglobin, produced by leguminous plants after colonization of S. meliloti, interacts with the free oxygen in the root nodule where the rhizobia reside. (wikipedia.org)
  • The typical structure of ITS, similar to that of test strain Rm1021, was dominant in native rhizobia population, while in one third of the isolates (33.3%) this sequence was different. (unifi.it)
  • However, the fre quency of divergent ITS types within the two groups of rhizobia depended on the host symbiotic preference observed in natural environment, allowing to speculate about the existence of a chromosome types specific for S. meliloti isolates with differential salt tolerance. (unifi.it)
Genes6
  • The S. meliloti genome contains four genes coding for flagellin. (wikipedia.org)
  • Indeterminate nodule symbiosis by S. meliloti is conferred by genes residing on pSymA. (wikipedia.org)
  • The proteins encoded by E. meliloti genes uvrA, uvrB and uvrC are employed in the repair of DNA damages by the process of nucleotide excision repair. (wikipedia.org)
  • However, E. meliloti mutants defective in either genes uvrA, uvrB or uvrC are sensitive to desiccation, as well as to UV light. (wikipedia.org)
  • Global sequence comparisons revealed that the greA-lpsB and lrp genes of S. meliloti have a genetic organization similar to that of their homologous loci in R. leguminosarum by. (uni-bielefeld.de)
  • The functional relationship between these two genes was demonstrated in genetic complementation experiments in which the S. meliloti lpsB gene restored the wild-type LPS phenotype when introduced into lpcC mutants of R. leguminosarum. (uni-bielefeld.de)
Bacteria2
  • Ensifer meliloti (formerly Rhizobium meliloti and Sinorhizobium meliloti) are an aerobic, Gram-negative, and diazotrophic species of bacteria. (wikipedia.org)
  • These compounds attract S. meliloti to the surface of the root hairs of the plant where the bacteria begin secreting nod factors. (wikipedia.org)
Tolerant1
Tolerance1
  • This finding indicates that the desiccation tolerance of wild-type E. meliloti depends on the repair of DNA damages that can be caused by desiccation. (wikipedia.org)
Wild-type1
  • Five S. meliloti genomes have been sequenced to date: Rm1021, AK83, BL225C, Rm41, and SM11 with 1021 considered to be the wild type. (wikipedia.org)
