Bacterial Associations with Legumes
TLDR
This review presents an overview of the associations of bacteria with legumes, the current available knowledge on the phylogenetic diversity of both Rhizobia and endophytic bacteria inhabiting root nodules, and the symbiotic features used to define symbiovars in rhizobia. Expand
Bacterial adaptation of respiration from oxic to microoxic and anoxic conditions: redox control.
TLDR
A compilation of the current knowledge about proteins and regulatory networks involved in the redox control of the respiratory adaptation of different bacterial species to microxic and anoxic environments is provided. Expand
Effects of soil biota from different ranges on Robinia invasion: acquiring mutualists and escaping pathogens.
TLDR
Comparisons of mutualistic and antagonistic biota in soils collected in the native, expanded, and invasive range of the black locust tree, Robinia pseudoacacia, suggest that important regional evolutionary relationships may occur among plants and soilBiota, and that net effects of soil biota may affect invasion, but in ways that are not easily explained by studying isolated components of the soil biOTA.

The contribution of bacteroidal nitrate and nitrite reduction to the formation of nitrosylleghaemoglobin complexes in soybean root nodules.
TLDR
It is shown that, in the presence of nitrate, all of the LbNO within normoxic nodules arises from nitrate reduction by the bacteroidal periplasmic nitrate reductase, whereas Nap activity is only responsible for half of the H2O within hypoxic nodule, and NirK is not essential for Lb NO formation under any condition tested. Expand
Molecular systematics of rhizobia based on maximum likelihood and Bayesian phylogenies inferred from rrs, atpD, recA and nifH sequences, and their use in the classification of Sesbania microsymbionts
TLDR
A well-resolved rhizobial species phylogeny with 51 haplotypes was inferred from a combined atpD + recA data set using Bayesian inference with best-fit, gene-specific substitution models, and complex and diverse phylogeographic, inheritance and host-association patterns were found for the symbiotic nifH locus. Expand
Production of nitric oxide and nitrosylleghemoglobin complexes in soybean nodules in response to flooding.
TLDR
It is proposed that Lb has a major role in detoxifying NO and nitrite produced by bacteroidal denitrification in response to flooding conditions, and is suggested to have a negative effect on expression of nitrogenase. Expand
Bradyrhizobium cytisi sp. nov., isolated from effective nodules of Cytisus villosus.
TLDR
Genotypic and phenotypic data obtained in this study suggest that the C. villosus strains represent a novel Bradyrhizobium species most closely related to B. canariense BTA-1(T), and the type strain is CTAW11(T) (=LMG 25866(T)=CECT 7749(T)). Expand
The Bradyrhizobium japonicum napEDABC genes encoding the periplasmic nitrate reductase are essential for nitrate respiration.
TLDR
Results suggest that the periplasmic nitrate reductase is the enzyme responsible for anaerobic growth of B. japonicum under nitrate-respiring conditions. Expand
Biological nitrogen fixation in the context of global change.
TLDR
Although nitrogen-fixing plants may be less productive, agriculture must significantly reduce the use of warming N and give priority to BNF if it is to sustain both food production and environmental health for a continuously growing human population. Expand
Carbon Monoxide Dehydrogenase Activity inBradyrhizobium japonicum
TLDR
The enzyme carbon monoxide dehydrogenase (CODH; EC 1.2.2 ) has been purified 21-fold, with a yield of 16% and a specific activity of 58 nmol of CO oxidized/min/mg of protein, by a procedure that involved differential ultracentrifugation, anion-exchange chromatography, hydrophobic interaction Chromatography, and gel filtration.
