Draft Genome Sequence of Sinorhizobium meliloti Strain AK170

Abstract

Root nodule bacteria of Sinorhizobium meliloti species live in a symbiotic relationship with alfalfa plants. We report here the draft genome sequence of S. meliloti strain AK170, recovered from nodules of Medicago orthoceras (Kar.

Molecular Phylogenetic Analysis of Salt-Tolerance-Related Genes in Root-Nodule Bacteria Species Sinorhizobium meliloti

“…The localization and copy number of the 14 genes involved in the response to salt shock and prolonged salt stress in S. meliloti in order to obtain knowledge about a stressrelated gene pool formation were determined for the first time. For this purpose, complete sequenced genomes of the 26 strains (including 4 strains whose genomes were previously sequenced by us [68][69][70][71]) were studied. The analysis of S. meliloti strains was carried out in comparison with the data obtained by us from the study of the genomes of the other 25 strains from different species belonging to four classes (α-, βand γ-proteobacteria, as well as Actinobacteria).…”

Complete Genome Sequence of Sinorhizobium meliloti Strain AK21, a Salt-Tolerant Isolate from the Aral Sea Region

“…The widespread interactions between the ␣-rhizobium Sinorhizobium meliloti and legumes of the Medicago genus are a model experimental system to investigate symbiosis (5-7). The two most recently published S. meliloti draft genome sequences correspond to strains AK170 and AK555, isolated from wildgrowing Medicago plants in northwest Kazakhstan in the Aral Sea region (8)(9)(10). This area suffers from man-made pollution, drought, and salinization, thus constituting a source of salt-tolerant rhizobia with expected increased symbiotic competence under these extreme conditions (11).…”
