    Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations of the.

Polyphasic evidence supporting the reclassification of Bradyrhizobium japonicum group Ia strains as Bradyrhizobium diazoefficiens sp. nov. Int J Syst Evol Microbiol. ;63(9)– The presence of cyclic β-1,,3-glucans in Bradyrhizobium merits discussion. Bradyrhizobium 32H1 and B. japonicum [, ], and two Bradyrhizobium spp. isolated from the nodules of tropical tree legumes have been demonstrated to produce cyclic β-1,,3-glucans.

    Field and greenhouse studies investigated microbiological interactions in Iowa soybean (Glycine max) rhizospheres. The effects of P fertilization on mycorrhizal development and rhizobial nodule occupancy were evaluated in a 2-year field study, and follow-up greenhouse experiments evaluated rhizobial strain competition. As expected, P fertilization significantly decreased mycorrhizal infection. The Rhizobium isolates from Leucaena leucocephala (strains BR , BR and BR ), Gliricidia sepium (strains BR , BR and BR ) and Bradyrhizobium sp. isolates from Lonchocarpus costatus (strains BR , BR and BR ) were previously shown to induce nitrogen fixing nodules on P. vulgaris[7,10].

A Bradyrhizobium sp. strain was described as a canthaxanthin producer and the carotenoid gene cluster was fully sequenced. Interest in canthaxanthin is decreasing since the discovery of extreme overdosage, that is, the deposition of minute crystals in the eye, a fact leading to adverse media attention in the past, and some pressure to limit its.

Although S is phylogenetically close to Bradyrhizobium japonicum USDA, a legume symbiont, it is unable to induce root nodules in siratro, a legume often used for testing Nod factor-dependent nodulation.

The genome of S is a single circular chromosome, 7, bp in length, with an average GC. Bradyrhizobium is a complex genus whose members form symbioses with many different legume species, including soybean, cowpea, and peanut. Numerous strains and even species of Bradyrhizobium have not yet been named (Willems et al.,Vinuesa et al.,Zhang et al., ), and little or no information is available on QS communication mechanisms in such species.

The symbiotic effectiveness of isolates from these soils was compared to that of Bradyrhizobium japonicum strain USDA The bradyrhizobial population sizes ranged from 0 to 10 4 cells g −1 soil. Bradyrhizobium sp. (TGx) populations were detected in 72% and.

Introduction. The genus Bradyrhizobium includes species of economically important soil bacteria that fix atmospheric nitrogen in symbiotic association with soybeans (Glycine max) and thereby minimize the requirement for nitrogen fertilizer inputs in crop production.
