Structure and biological roles of Sinorhizobium fredii HH103 exopolysaccharide
(Public Library of Science, 2014)
Here we report that the structure of the Sinorhizobium fredii HH103 exopolysaccharide (EPS) is composed of glucose, galactose, glucuronic acid, pyruvic acid, in the ratios 5:2:2:1 and is partially acetylated. A S. fredii ...

Sinorhizobium fredii HH103 invades lotus burttii by crack entry in a nod factor- and surface polysaccharide-dependent manner
(American Phytopathological Society, 2016)
Sinorhizobium fredii HH103-Rifr, a broad host range rhizobial strain, induces nitrogen-fixing nodules in Lotus burttii but ineffective nodules in L. japonicus. Confocal microscopy studies showed that Mesorhizobium loti ...
PhD Thesis
Regulación de la producción del Exopolisacárido en Sinorhizobium fredii HH103, un simbionte de la soja y otras leguminosas.
(2017-09-28)
Los rizobios son bacterias del suelo pertenecientes a las clases α- y β-Proteobacteria y que son capaces de llevar a cabo la fijación biológica del nitrógeno molecular en simbiosis con plantas leguminosas (Spaink et al., ...

A Set of Lotus japonicus Gifu × Lotus burttii Recombinant Inbred Lines Facilitates Map-based Cloning and QTL Mapping
(Oxford University Press, 2012)
Model legumes such as Lotus japonicus have contributed significantly to the understanding of symbiotic nitrogen fixation. This insight is mainly a result of forward genetic screens followed by map-based cloning to identify ...

Exopolysaccharide Production by Sinorhizobium fredii HH103 Is Repressed by Genistein in a NodD1-Dependent Manner
(Public Library of Science, 2016)
In the rhizobia-legume symbiotic interaction, bacterial surface polysaccharides, such as exopolysaccharide (EPS), lipopolysaccharide (LPS), K-antigen polysaccharide (KPS) or cyclic glucans (CG), appear to play crucial roles ...

Sinorhizobium fredii Strains HH103 and NGR234 Form Nitrogen Fixing Nodules With Diverse Wild Soybeans (Glycine soja) From Central China but Are Ineffective on Northern China Accessions
(Frontiers Media, 2018)
Sinorhizobium fredii indigenous populations are prevalent in provinces of Central China whereas Bradyrhizobium species (Bradyrhizobium japonicum, B. diazoefficiens, B. elkanii, and others) are more abundant in northern and ...

Bacterial Molecular Signals in the Sinorhizobium fredii-Soybean Symbiosis
(MDPI AG, 2016)
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 legumes, including plants forming ...
Article
A transcriptomic analysis of the effect of genistein on Sinorhizobium fredii HH103 reveals novel rhizobial genes putatively involved in symbiosis
(Nature Publishing Group, 2016)
Sinorhizobium fredii HH103 is a rhizobial soybean symbiont that exhibits an extremely broad host-range. Flavonoids exuded by legume roots induce the expression of rhizobial symbiotic genes and activate the bacterial protein ...
Article
Studies of rhizobial competitiveness for nodulation in soybean using a non-destructive split-root system
(AIMS Press, 2017)
Split-root systems (SRS) constitute an appropriate methodology for studying the relevance of both local and systemic mechanisms that participate in the control of rhizobia-legume symbioses. In fact, this kind of approach ...
