Sinorhizobium meliloti and medicae are two closely related species of the genus showing a similar host range, nodulating leguminous genera Medicago, Melilotus Trigonella, but their phylogenic relationship has not been elucidated yet. In this paper we report application three different molecular markers, (i) RFLP nodD genes, (ii) 16S-23S rDNA intergenic gene spacer fingerprinting (iii) amplification fragment length polymorphism to S. strains isolated from Caucasian area, which is region...
This paper explores the relationship between genetic diversity of rhizobia and morphological their plant hosts. Rhizobium galegae strains were isolated from nodules wild Galega orientalis officinalis in Caucasus, center origin for G. orientalis. All 101 isolates characterized by genomic amplified fragment length polymorphism fingerprinting PCR-restriction (RFLP) rRNA intergenic spacer five parts symbiotic region adjacent to nod box sequences. By all criteria, R. bv. form distinct clusters....
ABSTRACT Sinorhizobium meliloti was isolated from nodules and soil western Tajikistan, a center of diversity the host plants ( Medicago , Melilotus Trigonella species). There evidence recombination, but significant disequilibrium, between within chromosome megaplasmids. The most frequent alleles matched those in published genome sequence.
This paper presents a deep analysis of the accessory genome an economically promising strain Ensifer (Sinorhizobium) meliloti, L6-AK89, obtained as result next-generation high-throughput sequencing (MiSeq, MinIon). Strain L6-AK89 is StrR mutant native CIAM1775, symbiont Medicago lupulina that adapted to saline and arid habitat in NW Kazakhstan. CIAM1775 effective inoculant M. cv. Mira (fodder type standard), cultivated on moderately acid soils agricultural region Russia. makes it possible...
Legume plants can obtain combined nitrogen for their growth in an efficient way through symbiosis with specific bacteria. The between Rhizobium galegae and its host plant Galega is interesting case where the species G. orientalis officinalis form effective, nitrogen-fixing, symbioses only appropriate rhizobial counterpart, R. bv. officinalis, respectively. symbiotic properties of nitrogen-fixing rhizobia are well studied, but more information needed on plants. Caucasus region Eurasia has...
This paper presents the first in-depth research on biological and genomic properties of lytic rhizobiophage AP-J-162 isolated from soils mountainous region Dagestan (North Caucasus), which belongs to centers origin cultivated plants, according Vavilov N.I. The host strains are nitrogen-fixing bacteria genus Sinorhizobium spp., symbionts leguminous forage grasses. phage particles have a myovirus virion structure. genome is double-stranded DNA 471.5 kb in length; 711 ORFs annotated 41 types...
A series of Tn5-induced mutants which showed enhanced symbiotic effectiveness (Eff++) was isolated from Rhizobium meliloti strains CXM1-105 and CXM1-188. Alfalfa plants inoculated by the Eff++ had significantly higher shoot dry mass than parental strains. In greenhouse, most effective increased host 23-26% plant total nitrogen 23-27%. Interestingly, frequency in strain CXM1-188 (1.1% versus 0.4%); this also case for auxotrophic (1.2% 0.3% CXM1-105). Genetic analysis that cotransducible with...
The relationship between whole-cell redox potential, cytochrome composition in free-living culture and symbiotic activity of Sinorhizobium meliloti was studied. Three Tn5-induced mutants with increased cellular potential were generated. Stationary cultures Tb9 Tb16 contrast to the parental strain produced b-type terminal oxidase that may be similar symbiotically essential cbb3 Bradyrhizobium japonicum. Increase effectiveness all three O2 consumption rate observed. Mutants Tb1 also...
Abstract The aim of this work was to examine variation for activity symbiosis with Rhizobium meliloti in alfalfa, sweet clover and fenugreek. Seed specimens were obtained from the collection All‐Union Research Institute Plant Breeding strains Agricultural Microbiology, both Leningrad. Sterile methods vegetative culture employed. Statistical analysis data on inter‐ intracultivar allow one suppose that alfalfa clover, nitrogenase symbiotic efficiency (ability plants increase biomass after...
