Inactivation of the "Sinorhizobium fredii" HH103 "rhcJ" gene abolishes nodulation outer proteins (Nops) secretion and decreases the symbiotic capacity with soybean
(Sociedad Española de Microbiología, Viguera Editores, 2006)
Se ha propuesto que las proteínas externas de nodulación (Nops) impiden la nodulación efectiva de Sinorhizobium fredii USDA257 con las sojas americanas. S. fredii HH103 nodula de forma natural tanto conlas sojas asiáticas ...

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 ...

GunA of Sinorhizobium (Ensifer) fredii HH103 is a T3SS-secreted cellulase that differentially affects symbiosis with cowpea and soybean
(Springer, 2019-11-12)
Aims The symbiosis between Sinorhizobium fredii HH103 and its host legumes is influenced by the type 3 secretion system (T3SS), which delivers proteins (effectors) directly into the host cells to promote infection. GunA, ...

Nodulation-gene-inducing flavonoids increase overall production of autoinducers and expression of N-acyl homoserine lactone synthesis genes in rhizobia
(2011)
Legume-nodulating rhizobia use N-acyl homoserine lactones (AHLs) to regulate several physiological traits related to the symbiotic plant–microbe interaction. In this work, we show that Sinorhizobium fredii SMH12, Rhizobium ...

The Rhizobium tropici CIAT 899 NodD2 protein regulates the production of Nod factors under salt stress in a flavonoidindependent manner
(Nature Publishing Group, 2017)
In the symbiotic associations between rhizobia and legumes, NodD promotes the expression of the nodulation genes in the presence of appropriate flavonoids. This set of genes is implied in the synthesis of Nodulation factors, ...

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 ...

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 ...

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 ...
Artículo
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
(2014)
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 ...

Multitask approach to localize rhizobial type three secretion system effector proteins inside eukaryotic cells
(MDPI, 2023-05-28)
Rhizobia can establish mutually beneficial interactions with legume plants by colonizing their roots to induce the formation of a specialized structure known as a nodule, inside of which the bacteria are able to fix ...
