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....
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...
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...
Expression of quantitative traits characterizing the N2-fixing symbiosis nodule bacteria and leguminous plants is associated with operation evolutionary derived polygenic systems controlling symbiotic efficiency (SE) (impact inoculation on plant productivity) nodulation competitiveness (NC) (formation nodules by rhizobia under mixed inoculation). Optimization balance between positive negative regulators aimed at an increase nitrogenase activity a complete allocation its products into...
