Opening the "black box" of nodD3, nodD4 and nodD5 genes of Rhizobium tropici strain CIAT 899
(BioMed Central, 2015)
Background: Transcription of nodulation genes in rhizobial species is orchestrated by the regulatory nodD gene. Rhizobium tropici strain CIAT 899 is an intriguing species in possessing features such as broad host range, ...
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 ...
Transcriptomic studies of the effect of nod gene-inducing molecules in rhizobia: Different weapons, one purpose
(Multidisciplinary Digital Publishing Institute (MDPI), 2018)
Simultaneous quantification of transcripts of the whole bacterial genome allows the analysis of the global transcriptional response under changing conditions. RNA-seq and microarrays are the most used techniques to measure ...
MsPG3, a Medicago sativa polygalacturonase gene expressed during the alfalfa-Rhizobium meliloti interaction
(National Academy of Sciences, 1998)
Polygalacturonase (PG) is one of the most important enzymes associated with plant cell wall degradation. It has been proposed to participate in the early steps of the Rhizobium-legume interaction. We have identified two ...
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 ...
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 ...
Regulatory nodD1 and nodD2 genes of Rhizobium tropici strain CIAT 899 and their roles in the early stages of molecular signaling and host-legume nodulation
(BioMed Central Ltd., 2015)
Background: Nodulation and symbiotic nitrogen fixation are mediated by several genes, both of the host legume and of the bacterium. The rhizobial regulatory nodD gene plays a critical role, orchestrating the transcription ...
