The Genome of the Acid Soil-Adapted Strain OR191 Encodes Determinants for Effective Symbiotic Interaction With Both an Inverted Repeat Lacking Clade and a Phaseoloid Legume Host.

Although forms highly effective symbioses with the comparatively acid-sensitive genus , its introduction into acid soils appears to have selected for symbiotic interactions with acid-tolerant strains. has the unusual ability of being able to nodulate and fix nitrogen, albeit sub-optimally, not only with but also with the promiscuous host . Here we describe the genome of OR191 and genomic features important for the symbiotic interaction with both of these hosts.

Minimal standards for the description of new genera and species of rhizobia and agrobacteria.

Herein the members of the Subcommittee on Taxonomy of Rhizobia and Agrobacteria of the International Committee on Systematics of Prokaryotes review recent developments in rhizobial and agrobacterial taxonomy and propose updated minimal standards for the description of new species (and genera) in these groups. The essential requirements (minimal standards) for description of a new species are (1) a genome sequence of at least the proposed type strain and (2) evidence for differentiation from other species based on genome sequence comparisons. It is also recommended that (3) genetic variation within the species is documented with sequence data from several clearly different strains and (4) phenotypic features are described, and their variation documented with data from a relevant set of representative strains.

Biogeography of a Novel Ensifer meliloti Clade Associated with the Australian Legume Trigonella suavissima.

Here, we describe a novel clade within and consider how geographic and ecological isolation contributed to the limited distribution of this group. Members of the genus are best known for their ability to form nitrogen-fixing symbioses with forage legumes of three related genera, L., Mill.

Draft Genome Sequences of Respiratory and Urinary Tract Isolates of Acinetobacter baumannii from the Same Patient.

Acinetobacter baumannii is a frequent hospital-acquired human pathogen. This report describes the draft genome sequences of two distinct A. baumannii clinical isolates from the same patient.

Development and application of a multilocus sequence analysis method for the identification of genotypes within genus Bradyrhizobium and for establishing nodule occupancy of soybean (Glycine max L. Merr).

A multilocus sequence typing (MLST) method based on allelic variation of seven chromosomal loci was developed for characterizing genotypes (GT) within the genus Bradyrhizobium. With the method, 29 distinct multilocus GT were identified among 190 culture collection soybean strains. The occupancy of 347 nodules taken from uninoculated field-grown soybean plants also was determined.
