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 ...
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 ...
The symbiotic biofilm of Sinorhizobium fredii SMH12, necessary for successful colonization and symbiosis of glycine max cv osumi, is regulated by quorum sensing systems and inducing Flavonoids via NodD1
Bacterial surface components, especially exopolysaccharides, in combination with bacterial Quorum Sensing signals are crucial for the formation of biofilms in most species studied so far. Biofilm formation allows soil ...
A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes
(Sociedad Española de Microbiología. Viguera Editores, 2007)
Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media. The mutated gene, pyrF, codes for an ...
The Sinorhizobium (Ensifer) fredii HH103 nodulation outer protein NopI is a determinant for efficient nodulation of soybean and cowpea plants
(American Society for Microbiology, 2017)
The type III secretion system (T3SS) is a specialized secretion apparatus that is commonly used by many plant and animal pathogenic bacteria to deliver proteins, termed effectors, to the interior of the host cells. These ...
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 ...
