Gram-stain-negative strains V5/3MT, V5/5K, V5/5M and V5/13 were isolated from root nodules of Vicia alpestris plants growing in the North Ossetia region (Caucasus). Sequencing partial 16S rRNA gene (rrs) four housekeeping genes (dnaK, gyrB, recA rpoB) showed that isolates V. most closely related to species Microvirga zambiensis (order Rhizobiales , family Methylobacteriaceae ) which was described for single isolate nodule Listia angolensis Zambia. Sequence similarities between -related M....
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....
Twenty-two rhizobia strains isolated from three distinct populations (North Ossetia, Dagestan, and Armenia) of a relict legume Vavilovia formosa were analysed to determine their position within Rhizobium leguminosarum biovar viciae (Rlv). These bacteria are described as symbionts four plant genera Pisum, Vicia, Lathyrus, Lens the Fabeae tribe, which is considered be closest its last common ancestor (LCA). In contrast viciae, trifolii (Rlt) inoculate plants Trifolieae tribe. Comparison...
Crop rotation is one of the oldest and most effective methods restoring soil fertility, which declines when same plant grown repeatedly. One reasons for a reduction in fertility accumulation pathogenic unfavorable microbiota. The modern crop schemes (a set species their order rotation) are highly but designed without considering microbiota dynamics. main goal this study was to perform short-term experiment with multiple combinations access microbiological effects rotation. It could be useful...
Background. Alfalfa root nodule bacteria (Sinorhizobium meliloti) are among the most active symbiotic N2-fixers. Their efficiency (SE) defined as an ability to enhance productivity of inoculated host plants is polygenic trait controlled by a complicated system genes, inactivation which can result in either decrease or increase SE. Analysis previously identified eff-genes, whose mutations SE increase, revealed their location different parts genome (chromosome megaplasmids) and demonstrated...
