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 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 کاملBradyrhizobium japonicum Survival in and Soybean Inoculation with Fluid Gels.
The utilization of gels, which are used for fluid drilling of seeds, as carriers of Bradyrhizobium japonicum for soybean (Glycine max (L.) Merr.) inoculation was studied. Gels of various chemical composition (magnesium silicate, potassium acrylate-acrylamide, grafted starch, and hydroxyethyl cellulose) were used, although the hydroxyethyl cellulose gels were more extensively investigated. Gel i...
متن کاملSymbiotic effect of Bradyrhizobium yuanmingense isolates over Bradyrhizobium japonicum with soybean
Symbiotic effect of twenty one indigenous Bradyrhizobium yuanmingense strains obtained from nodules of soybean cultivated in India was comparatively evaluated with B. japonicum ASR011 on soybean cv. JS335 for improved nodulation and plant growth performance under greenhouse conditions. Significant variation in symbiotic potential among native B. yuanmingense strains was observed and few of them...
متن کاملPromoter selectivity of the Bradyrhizobium japonicum RpoH transcription factors in vivo and in vitro.
Expression of the dnaKJ and groESL1 heat shock operons of Bradyrhizobium japonicum depends on a sigma32-like transcription factor. Three such factors (RpoH1, RpoH2, and RpoH3) have previously been identified in this organism. We report here that they direct transcription from some but not all sigma32-type promoters when the respective rpoH genes are expressed in Escherichia coli. All three RpoH...
