Agromonas oligotrophica JCM 1494T was isolated in Japan in 1983, and the name was validly published in 1985. Analysis of the 16S rRNA gene sequence showed that Agromonas oligotrophica LMG 10732T ( = JCM 1494T) is located within the genus Bradyrhizobium , with Bradyrhizobium denitrificans LMG 8443T as its closest relative, showing 99.6 % 16S rRNA gene sequence identity. However, Agromonas oligotrophica LMG 10732T and Bradyrhizobium denitrificans LMG 8443T can be distinguished by housekeeping gene sequence analysis, phenotypic characterization and DNA-DNA hybridization. Agromonas oligotrophica is also genotypically and phenotypically different from the remaining species of the genus Bradyrhizobium , and we therefore propose the reclassification of Agromonas oligotrophica into the genus Bradyrhizobium as Bradyrhizobium oligotrophicum comb. nov. (type strain LMG 10732T = JCM 1494T = ATCC 43045T).
This research aimed to determine the effect of brown seaweed extract and Bradyrhizobium japonicum and their interaction to increase N availability and Soybean Production. This research was conducted in the green house and Soil Biology laboratory of Fakultas Pertanian USU in Juny-October 2014, used Randomized Block Design (RBD) factorial consisting of 2 factors and 3 replications. The first factor was brown seaweed extract concentration consisting of 4 treatments (0, 10, 20 and 30 %/polybag) and the second factor was Bradyrhizobium japonicum consisting of 2 treatments (with and without Bradyrhizobium japonicum). The result showed that brown seaweed extract significantly affected increase number and weight of root nodule, shoot dry and root weight, number and weight of seed, and N absorption but not significantly affected increase C-organic, plant height, number of branch, and decrease soil pH, N-availability of soil and plant. Bradyrhizobium japonicum significantly affected increase number and ...
Differential RNA-sequencing (dRNA-seq) is indispensable for determination of primary transcriptomes. However, using dRNA-seq data to map transcriptional start sites (TSSs) and promoters genome-wide is a bioinformatics challenge. We performed dRNA-seq of Bradyrhizobium japonicum USDA 110, the nitrogen-fixing symbiont of soybean, and developed algorithms to map TSSs and promoters. A specialized machine learning procedure for TSS recognition allowed us to map 15,923 TSSs: 14,360 in free-living bacteria, 4329 in symbiosis with soybean and 2766 in both conditions. Further, we provide proteomic evidence for 4090 proteins, among them 107 proteins corresponding to new genes and 178 proteins with N-termini different from the existing annotation (72 and 109 of them with TSS support, respectively). Guided by proteomics evidence, previously identified TSSs and TSSs experimentally validated here, we assign a score threshold to flag 14 % of the mapped TSSs as a class of lower confidence. However, this class of lower
Analysis of the Bradyrhizobium japonicum hemH gene and its expression in Escherichia coli. Fur-independent regulatin of iron metabolism by Irr in Bradyrhizobium japonicum
Nucleotide excision repair (NER) is a mechanism to recognize and repair bulky DNA damage caused by compounds, environmental carcinogens, and exposure to UV-light. In humans hereditary defects in the NER pathway are linked to at least three diseases: xeroderma pigmentosum (XP), Cockayne syndrome (CS), and trichothiodystrophy (TTD). The repair of damaged DNA involves at least 30 polypeptides within two different sub-pathways of NER known as transcription-coupled repair (TCR-NER) and global genome repair (GGR-NER). TCR refers to the expedited repair of lesions located in the actively transcribed strand of genes by RNA polymerase II (RNAP II). In GGR-NER the first step of damage recognition involves XPC-hHR23B complex together with XPE complex (in prokaryotes, uvrAB complex). The following steps of GGR-NER and TCR-NER are similar ...

Bradyrhizobium japonicum bradavidin protein: a biotin-binding protein that, due to its different immunoreactivity, may prove useful in gene therapy, imaging, and drug delivery; amino acid sequence in first source
FixK2 is a regulatory protein that activates a large number of genes for the anoxic and microoxic, endosymbiotic, and nitrogen-fixing life styles of the α-proteobacterium Bradyrhizobium japonicum. FixK2 belongs to the cAMP receptor protein (CRP) superfamily. Although most CRP family members are coregulated by effector molecules, the activity of FixK2 is negatively controlled by oxidation of its single cysteine (Cys-183) located next to the DNA-binding domain and possibly also by proteolysis. Here, we report the three-dimensional x-ray structure of FixK2, a representative of the FixK subgroup of the CRP superfamily. Crystallization succeeded only when (i) an oxidation- and protease-insensitive protein variant (FixK2(C183S)-His6) was used in which Cys-183 was replaced with serine and the C terminus was fused with a hexahistidine tag and (ii) this protein was allowed to form a complex with a 30-mer double-stranded target DNA. The structure of the FixK2-DNA complex was solved at a resolution of ...

Regulation of heme metabolism, iron homeostasis and oxidative stress. The adaptive success of bacteria depends, in part, on the ability to sense and respond to external cues at the level of gene expression. Bradyrhizobium japonicum resides as a free-living soil bacterium or as the endosymbiont of soybean with root nodules. In addition to its agricultural significance, B. japonicum also serves as a model to study bacteria-eukaryote interactions more generally, including related pathogens that are refractive to genetic and biochemical study. We are interested in the regulation of heme metabolism and its integration with iron homeostasis in B. japonicum. Hemes are needed for many cellular processes, and we have shown that heme plays important regulatory roles in cells. We are interested in the molecular basis of this novel regulatory mechanism. We identified the iron response regulator (Irr) protein as a regulator that couples heme biosynthesis with global iron metabolism. Irr responds to the iron ...

Preliminary Analysis of Soybean Gene Expression Response to a Bradyrhizobium japonicum Type III Secretion System Mutant [abstract]. 4th International Conference on Legume Genomics and Genetics, December 7-12, 2008, Puerto Vallarta, Mexico. 2008 CDROM. Interpretive Summary: Technical Abstract: Plant pathogens deliver proteinaceous effector molecules into their host via complex secretion systems, such as the type III secretion system (T3SS). Some of these T3SS effectors have been shown to function as suppressors of host defense responses. The role of the T3SS during plant interactions with symbionts is just beginning to be characterized. The symbiont, Bradyrhizobium japonicum, has a T3SS that is required for proper nodulation of soybean (2002 MPMI 15:1228-1235). Affymetrix gene chip analysis of soybean root-hair response to a T3SS mutant and wild-type B. japonicum versus mock inoculation at 6, 12, and 18 hours ...

1JFU: Structure of the soluble domain of a membrane-anchored thioredoxin-like protein from Bradyrhizobium japonicum reveals unusual properties.
Here, I will present the recently discovered regulation of nos genes through the two-component system NasST. NasS is a nitrate sensor and NasT is a transcription antiterminator. Mutation of nasS induced both N2O reductase activity and transcription of nos genes (nosRZD), in cells of B. diazoefficiens incubated in the absence of nitrate. The NasS_NasT protein complex was dissociated in vitro by the addition of nitrate, suggesting the release of NasT, which is known to bind the leader RNA of the target gene, thereby preventing hairpin formation and allowing complete transcription. Disruption of nasT led to a marked decrease in nos transcription in B. diazoefficiens cells incubated with nitrate, indicating that NasST system regulates nos transcription in response to nitrate. Although analysis of the region upstream nosR and nosZ genes revealed no regulatory hairpin structures similar to those present in the leader RNA of other genes regulated by NasT, we could confirm binding of purified NasT with ...

BACKGROUND: Immunosuppression is associated with a variety of idiopathic clinical syndromes that may have infectious causes. It has been hypothesized that the cord colitis syndrome, a complication of umbilical-cord hematopoietic stem-cell transplantation, is infectious in origin. METHODS: We performed shotgun DNA sequencing on four archived, paraffin-embedded endoscopic colon-biopsy specimens obtained from two patients with cord colitis. Computational subtraction of human and known microbial sequences and assembly of residual sequences into a bacterial draft genome were performed. We used polymerase-chain-reaction (PCR) assays and fluorescence in situ hybridization to determine whether the corresponding bacterium was present in additional patients and controls. RESULTS: DNA sequencing of the biopsy specimens revealed more than 2.5 million sequencing reads that did not match known organisms. These sequences were computationally assembled into a 7.65-Mb draft genome showing a high degree of ...

Certain strains of Bradyrhizobium japonicum form a previously unknown polysaccharide in the root nodules of soybean plants (Glycine max (L.) Merr.). The polysaccharide accumulates inside of the symbiosome membrane-the plant-derived membrane enclosing the bacteroids. In older nodules (60 days after planting), the polysaccharide occupies most of the symbiosome volume and symbiosomes become enlarged so that there is little host cytoplasm in infected cells. The two different groups of B. japonicum which produce different types of polysaccharide in culture produce polysaccharides of similar composition in nodules. Polysaccharide formed by group I strains (e.g., USDA 5 and USDA 123) is composed of rhamnose, galactose, and 2-O-methylglucuronic acid, while polysaccharide formed by group II strains (e.g., USDA 31 and USDA 39) is composed of rhamnose and 4-O-methylglucuronic acid. That the polysaccharide is a bacterial product is indicated by its composition plus the fact that polysaccharide formation is ...

At the time of this study, the available Affymetrix soybean DNA microarray consisted of 37,641 features derived from over 350,000 EST sequences that were available at the time of the design. The recent release of the soybean genome sequence and prediction of associated genes enabled reexamination of the content and updated curation of this array. Accordingly, we blasted each probe set against the predicted soybean cDNA sequences (http://www.phytozome.net/soybean). A total of 34,015 probe sets (90.5%) matched against soybean cDNA sequences, while 3,578 (9.5%) did not (Supplemental Fig. S1; Supplemental Table S1). These 34,015 probe sets were divided into three categories, associated with one (13,949, 37.1%), two (16,509, 43.9%), and three or more (3,557, 9.5%) predicted soybean genes (Supplemental Fig. S1; Supplemental Table S1). The first category of probe sets targets 11,426 soybean genes (i.e. several probe sets match with the same gene). The second and third categories of probe sets target ...
Nodules are a growth on the roots of leguminous plants where the bacteria reside. The plant roots secrete amino acids and sugars into the rhizosphere. The rhizobia move toward the roots and attach to the root hairs. The plant then releases flavanoids, which induce the expression of nod genes within the bacteria. The expression of these genes results in the production of enzymes called Nod factors that initiate root hair curling. During this process, the rhizobia are curled up with the root hair. The rhizobia penetrate the root hair cells with an infection thread that grows through the root hair into the main root. This causes the infected cells to divide and form a nodule. The rhizobia can now begin nitrogen fixation.. ...

Introduction. Background. Bartonella fall within the alpha-2 subgroup of the class Proteobacteria (Jacomo, Kelly & Raoult 2002). Recent studies have indicated that Bartonella species (spp.) have some degree of relatedness to other alpha-2 Proteobacteria including Brucella species, Afipia species, Agrobacterium tumefaciens, Bradyrhizobium species, and Bosea species (Duncan, Maggi & Breitschwerdt 2007; Greub & Raoult 2002; Houpikian & Raoult 2001; Jacomo et al. 2002; Pretorius, Beati & Birtles 2004; Rolain et al. 2004). Current knowledge suggests that there are more than 20 species and subspecies included within this genus (Márquez et al. 2008). Approximately 13 species have been associated with human diseases (Pérez-Martínez et al. 2009; Maggi et al. 2009; Pons et al. 2008) affecting both immunocompetent and immunocompromised individuals. At least six species affecting humans have been isolated from domestic cats and dogs (Chomel et al. 2006).. Bartonellae are pleomorphic, fastidious, ...
Play media In molecular biology, the iron response element or iron-responsive element (IRE) is a short conserved stem-loop which is bound by iron response proteins (IRPs, also named IRE-BP or IRBP). The IRE is found in UTRs (untranslated regions) of various mRNAs whose products are involved in iron metabolism. For example, the mRNA of ferritin (an iron storage protein) contains one IRE in its 5 UTR. When iron concentration is low, IRPs bind the IRE in the ferritin mRNA and cause reduced translation rates. In contrast, binding to multiple IREs in the 3 UTR of the transferrin receptor (involved in iron acquisition) leads to increased mRNA stability. The two leading theories describe how iron probably interacts to impact posttranslational control of transcription. The classical theory suggests that IRPs, in the absence of iron, bind avidly to the mRNA IRE. When Iron is present, it interacts with the protein to cause it to release the mRNA. For example, In high iron conditions in humans, IRP1 ...
Stephanie Stockwell maintains a research program involving the molecular characterization of the B. japonicum/soybean symbiosis. As an extension of work done in the laboratory of Mary Lou Guerinot, Ph. D. (Dartmouth College), this program is focused on the genetic and molecular characterization of the symbiotic interaction between Gram negative soil bacterium, Bradyrhizobium japonicum, and it leguminous host plant, soybean. During the symbiosis, the bacteria fix atmospheric nitrogen for use by the plant, thereby decreasing the need for supplemental nitrogen fertilizers in large-scale agriculture. Work in the Stockwell lab includes creating mutant B. japonicum strains lacking iron uptake and signal transduction genes, critical for the adaptation to and survival within the host environment. These mutant strains serve as tools for identifying in planta specific signaling networks required for a functional symbiosis. The role of the dual-function ferrichrome uptake receptor, FegA, is of particular ...
Background: Biological nitrogen fixation in root nodules is a process of great importance to crops of soybean [Glycine max (L.) Merr.], as it may provide the bulk of the plants needs for nitrogen. Legume nodulation involves several complex steps and, although studied for many decades, much remains to be understood. Results: This research aimed at analyzing the global expression of genes in soybean roots of a Brazilian cultivar (Conquista) inoculated with Bradyrhizobium japonicum CPAC 15, a strain broadly used in commercial inoculants in Brazil. To achieve this, we used the suppressive subtractive hybridization (SSH) technique combined with Illumina sequencing. The subtractive library (non-inoculated x inoculated) of soybean roots resulted in 3,210 differentially expressed transcripts at 10 days after inoculation were studied. The data were grouped according to the ontologies of the molecular functions and biological processes. Several classes of genes were confirmed as related to N-2 fixation ...
The procedure for the preparation of this complex involves the following steps. 10 mM of stock solution of luteolin is prepared in acetone. One ml of this stock is added to 1 ml of aqueous solution of neutral cyclic-b (1,2)-glucan. The mixture is kept under shaking for 24 h at 30 °C, then partially evaporated, lyophilized, and mixed with 1 ml of distilled water. 4 lm membrane filter. The product could be analyzed and quantified with a HPLC. Changes in the NMR peak shape and chemical shift is observed after complexation. 4), is another glucan produced by Bradyrhizobium sp. (Miller et al. 1990). It is smaller than the cyclic b-(1,2)-glucans produced by Agrobacterium and Rhizobium species. There are very brief mention of other cyclic glucans in the literature including b-(1,3)-(1,4)-D-glucans which are the predominant components of cereal grain cell walls including barley and oats (Laroche and Michaud 2007). 1 (Zevenhuizen 1984; Kawaharada et al. 2008; Amemura 1984; Zevenhuizen et al. 1990; ...
Seed inoculation is the perform of successfully introducing a excessive variety of nitrogen-fixing micro organism (Rhizobium or Bradyrhizobium) at the floor of legume seeds sooner than planting. The micro organism penetrates the basis, leading to the formation of root nodules that repair nitrogen from the air, and make it available to the plant. This ebook describes the necessity, the improvement and using rhizobia, and the way this procedure could be reproduced effectively worldwide, specially in underdeveloped agricultural countries.. ...
The limits of water treatment to control microbial regrowth were examined using highly purified waters. Measurable microbial genetic material was detected in the product water in a survey of thirteen laboratory pure water systems. Illumina 16S rRNA gene amplicon sequencing revealed surprisingly diverse microbial assemblages, confirmed to be active in bioassays, with no direct relationship to quality or maintenance of the systems. With storage under both light and dark conditions, a 2-log increase in bacterial genetic markers was observed within 10 days, indicating viable oligotrophic communities despite rigorous treatment steps. With growth, microbial communities shifted concurrent with enrichment of Proteobacteria groups capable of nitrogen fixation (Bradyrhizobium) and H2 oxidation (Comamonadaceae). This study has implications not only for laboratory studies, which rely on highly purified waters, but also for municipal drinking water, which depends on treatment to reduce nutirents sufficiently ...

In a soybean transcriptome expression study focused on B. japonicum-induced nodulation, Brechenmacher et al. (2008) reported that the mRNA abundance of approximately 5,000 genes changed significantly within 16 dpi in young roots. Some of the differentially expressed genes identified from that study were subsequently shown to play critical roles in soybean nodulation, such as FW2.2-like1 (Libault et al., 2010b), GS52 ecto-apyrase (Govindarajulu et al., 2009; Tanaka et al., 2011), and CND (for control of nodule development), encoding a Myb transcription factor (Libault et al., 2009). Additionally, in a recent study, Nguyen et al. (2012) conducted experiments on quantitative phosphoproteomics where 273 phosphopeptides corresponding to 240 phosphoproteins were found to be significantly regulated in soybean root hairs in response to B. japonicum inoculation, reflecting a critical role of phosphorylation events during the initiation of the B. japonicum infection process. Here, we report another ...
Rhizobium, Bradyrhizobium, and Azorhizobium species are able to elicit the formation of unique structures, called nodules, on the roots or stems of the leguminous host. In these nodules, the rhizobia convert atmospheric N2 into ammonia for the plant. To establish this symbiosis, signals are produced early in the interaction between plant and rhizobia and they elicit discrete responses by the two symbiotic partners. First, transcription of the bacterial nodulation (nod) genes is under control of the NodD regulatory protein, which is activated by specific plant signals, flavonoids, present in the root exudates. In return, the nod-encoded enzymes are involved in the synthesis and excretion of specific lipooligosaccharides, which are able to trigger on the host plant the organogenic program leading to the formation of nodules. An overview of the organization, regulation, and function of the nod genes and their participation in the determination of the host specificity is presented.. ...
