(ndvC) influencing beta-(1->6) linkages.

To elucidate how temperature affects bradyrhizobial ecology, long-term incubations of Bradyrhizobium japonicum USDA 6(T), 38, and 123 and of Bradyrhizobium elkanii USDA 76(T) were conducted under various temperature conditions. Proliferative traits in liquid culture and population occupancies in soil microcosms were compared. The occupancies of USDA 76(T) and USDA 123 in soil microcosms during ...

The symbiosis of Bradyrhizobium sp. BTAi1 with its host plant Aeschynomene indica relies on a Nod-factor independent mechanism, wherein the Bradyrhizobium O-antigen is regarded as a key factor. This O-antigen polysaccharide is composed of a unique C10 monosaccharide, namely bradyrhizose, which has a galactose-inositol trans-fused scaffold, via a homogeneous α-(1 → 7)-linkage. Herein, we report ...

Bradyrhizobium sp. Th.b2 is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an effective nitrogen-fixing root nodule of Amphicarpaea bracteata collected in Johnson City, New York. Here we describe the features of Bradyrhizobium sp. Th.b2, together with high-quality permanent draft genome sequence information and annotation. The 10,118,060 high-quality draft genom...

Many researchers consider the use of different probes for hybridization assays as suitable for studying the genetic diversity of nitrogen fixing bacteria. In this study for asessing genetic diversity among Bradyrhizobium japonicum isolates, two different probes (sucA and topA) chosen from the chromosomal genome of Bradyrhizobium strain USDA 110 were designed, evaluated by DNAMAN software and im...

The taxonomy of N2-fixing bacteria belonging to the genus Bradyrhizobium is still poorly refined. This paper presents an application of a method aiming the identification of possible new clusters within a Brazilian collection of 119 Bradyrhizobium strains showing phenotypic characteristics of B. japonicum and B. elkanii. The stability has been studied as a function of the number of restriction ...

Competitiveness of Bradyrhizobium japonicum inoculation strain for soybean nodule occupancy | Dragana Miljakovic, Jelena Marinkovi?, Maja Ignjatov, Milosevi?, Zorica Nikoli?, Branislava Tintor, Vojin ?uki? Agricultural Journals

Soybean bradyrhizobia form root nodules on soybean plants and symbiotically fix N2 Strain J5 is phylogenetically far from well-known representatives within the Bradyrhizobium japonicum linage. The complete genome showed the largest single chromosomal (10.1 Mb) and symbiosis island (998 kb) among complete genomes of soybean bradyrhizobia.
