UnknownComplete Genome Sequence of Bradyrhizobium japonicum J5, Isolated from a Soybean Nodule in Hokkaido, Japan.
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 com...

UnknownNew Bradyrhizobium japonicum strains that possess high copy numbers of the repeated sequence RS alpha.
In a survey of DNA fingerprints of indigenous Bradyrhizobium japonicum with the species-specific repeated sequences RS alpha and RS beta, 21 isolates from three field sites showed numerous RS-specific hybridization bands. The isolates were designated highly reiterated sequence-possessing (HRS) isola...

UnknownSymbiosis island shuffling with abundant insertion sequences in the genomes of extra-slow-growing strains of soybean bradyrhizobia.
Extra-slow-growing bradyrhizobia from root nodules of field-grown soybeans harbor abundant insertion sequences (ISs) and are termed highly reiterated sequence-possessing (HRS) strains. We analyzed the genome organization of HRS strains with the focus on IS distribution and symbiosis island structure...

UnknownMicrobial community analysis of field-grown soybeans with different nodulation phenotypes.
Microorganisms associated with the stems and roots of nonnodulated (Nod(-)), wild-type nodulated (Nod(+)), and hypernodulated (Nod(++)) soybeans [Glycine max (L.) Merril] were analyzed by ribosomal intergenic transcribed spacer analysis (RISA) and automated RISA (ARISA). RISA of stem samples detecte...

UnknownPreferential association of endophytic bradyrhizobia with different rice cultivars and its implications for rice endophyte evolution.
Plant colonization by bradyrhizobia is found not only in leguminous plants but also in nonleguminous species such as rice. To understand the evolution of the endophytic symbiosis of bradyrhizobia, the effect of the ecosystems of rice plantations on their associations was investigated. Samples were c...

UnknownBacterial clade with the ribosomal RNA operon on a small plasmid rather than the chromosome.
rRNA is essential for life because of its functional importance in protein synthesis. The rRNA (rrn) operon encoding 16S, 23S, and 5S rRNAs is located on the "main" chromosome in all bacteria documented to date and is frequently used as a marker of chromosomes. Here, our genome analysis of a plant-a...

UnknownMetaproteomic identification of diazotrophic methanotrophs and their localization in root tissues of field-grown rice plants.
In a previous study by our group, CH4 oxidation and N2 fixation were simultaneously activated in the roots of wild-type rice plants in a paddy field with no N input; both processes are likely controlled by a rice gene for microbial symbiosis. The present study examined which microorganisms in rice r...

UnknownComplete Genome Sequence of the Soybean Symbiont Bradyrhizobium japonicum Strain USDA6T.
The complete nucleotide sequence of the genome of the soybean symbiont Bradyrhizobium japonicum strain USDA6T was determined. The genome of USDA6T is a single circular chromosome of 9,207,384 bp. The genome size is similar to that of the genome of another soybean symbiont, B. japonicum USDA110 (9,10...

UnknownAnaerobic nitrogen-fixing consortia consisting of clostridia isolated from gramineous plants.
We report here the existence of anaerobic nitrogen-fixing consortia (ANFICOs) consisting of N(2)-fixing clostridia and diverse nondiazotrophic bacteria in nonleguminous plants; we found these ANFICOs while attempting to overcome a problem with culturing nitrogen-fixing microbes from various gramineo...
