Thiosulfate-dependent chemolithoautotrophic growth of Bradyrhizobium japonicum.
Thiosulfate-oxidizing sox gene homologues were found at four loci (I, II, III, and IV) on the genome of Bradyrhizobium japonicum USDA110, a symbiotic nitrogen-fixing bacterium in soil. In fact, B. japonicum USDA110 can oxidize thiosulfate and grow under a chemolithotrophic condition. The deletion mutation of the soxY(1) gene at the sox locus I, homologous to the sulfur-oxidizing (Sox) system in...
متن کاملcombination of trichoderma species and bradyrhizobium japonicum in control of phytophthora sojae and soybean growth
soybean, glycine max (l.) merr is one of the most important oilseed plants in the world and phythophthora root and crown rot is a significant limiting factor for its planting. in the present study the antagonistic effect of 12 trichoderma spp. in vitro and these trichoderma spp. in combination with bradyrhizobium japonicum in vivo on phytophthora sojae and soybean growth were tested. in laborat...
متن کاملevaluation of trifluralin, metribuzin and imazethapyr herbicides effects on bradyrhizobium japonicum isolates growth
abstractgrowth of b. japonicum isolates at different concentrations of herbicide used on soybean was studied as factorial experiment arranged in a completely randomized design with three replications. isolates b1, b6, b43 and 0, 0.125, 0.25, 0.5, 1, 2, 4, 8 and 16 folded of the recommended doses of trifluralin, metribuzin and imazethapyr herbicides were considered as factors. isolates populatio...
متن کاملChemotaxis of Bradyrhizobium japonicum to soybean exudates.
The chemotactic response of Bradyrhizobium japonicum toward soybean seed and root exudates was examined. Assays using various isoflavones and fractionated exudate indicated that isoflavones are not the principal attractants in exudates. Likewise, induction of nod genes with isoflavones or seed exudate before assay did not enhance chemotaxis. Screening of numerous compounds revealed that only di...
متن کاملSynthesis of Exopolysaccharide by Bradyrhizobium japonicum during Growth on Hydroaromatic Substrates.
The hydroaromatic acids shikimate and quinate, which may be available as carbon sources in the soil, supported production of only low levels of acidic exopolysaccharide by Bradyrhizobium japonicum. Exopolysaccharide production (micrograms per 10 cells) was 4.9 on quinate and 4.5 on shikimate; in comparison, it was 128 on adipate, 18 on l-arabinose, and 39 on d-glucose.
