Covering: bacterial genome sequences to 2005 and post-genomic literature to June 2006 A
total of 223 complete bacterial genomes are analyzed, with 281 citations, for the presence of …

Sinorhizobium (Ensifer) fredii (S. fredii) is a rhizobial species exhibiting a remarkably broad
nodulation host-range. Thus, S. fredii is able to effectively nodulate dozens of different …

The soil bacterium Sinorhizobium meliloti is capable of entering into a nitrogen-fixing
symbiosis with Medicago sativa (alfalfa). Particular low-molecular-weight forms of certain …

Background Rhizobium tropici CIAT 899 and Rhizobium sp. PRF 81 are α-Proteobacteria
that establish nitrogen-fixing symbioses with a range of legume hosts. These strains are …

This article describes the occurrence of the acidic sugars based on pseudaminic acid and
legionaminic acid within pathogenic Gram-negative bacteria. In addition to presenting the …

Exopolysaccharides (EPSs) and K polysaccharides (K-antigens, capsular polysaccharides,
or KPSs) are important for the recognition of the symbiotic partner and the infection process …

The production of exopolysaccharide (EPS) was shown to be required for the infection
process by rhizobia that induce the formation of indeterminate nodules on the roots of …

The Sinorhizobium fredii HH103 rkp-1 region, which is involved in capsular polysaccharides
(KPS) production, was isolated and sequenced. The organization of the S. fredii genes …

Molecular signals, including Nod factors and succinoglycan, are necessary for the
establishment of nitrogen-fixing nodules (Fix+) in Medicago truncatula-Sinorhizobium …

The bacterial surface is the first line of defense against antimicrobial molecules and stress
caused by changes in the environment surrounding the bacterium. In the case of plant-and …
