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)

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)
Alfalfa2
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)
In conclusion, we propose that in the area subjected to secondary salinization, which are also the centre of introgressive hybridization of alfalfa, microevolutionary processes, affecting rrnoperons and associated with salt adaptation, are also occurring in symbiotic root nod ule bacteria populations.

Tolerant1
E. meliloti is a desiccation tolerant bacterium. (wikipedia.org)
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)
Rhizobia2
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)
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)
Specific1
The accessory genome is thought to be an important source of genetic variability in bacterial populations and is gained through lateral gene transfer, allowing subpopulations of bacteria to better adapt to specific niches. (biomedcentral.com)
Root3
These compounds attract S. meliloti to the surface of the root hairs of the plant where the bacteria begin secreting nod factors. (wikipedia.org)
Through the infection thread, the bacteria move toward the main root. (wikipedia.org)
