Role of surface tryptophan for peroxidase oxidation of nonphenolic lignin
(BMC (part of Springer Nature), 2016)
Background: Despite claims as key enzymes in enzymatic delignification, very scarce information on the reaction rates between the ligninolytic versatile peroxidase (VP) and lignin peroxidase (LiP) and the lignin polymer ...

Plant Growth-Promoting Rhizobacteria Modulate the Concentration of Bioactive Compounds in Tomato Fruits
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)
Background: The application of microorganisms as bioestimulants in order to increase the yield and/or quality of agricultural products is becoming a widely used practice in many countries. In this work, five plant ...

The Role of Two Linear β-Glucans Activated by c-di-GMP in Rhizobium etli CFN42
(MDPI, 2022)
Bacterial exopolysaccharides (EPS) are secreted biopolymers with often critical roles in bacterial physiology and ecology. In addition to their biological role, there is increasing interest for EPS in various industrial ...

Estudio estructural de los polisacáridos capsulares de Sinorhizobium Fredii
(1999-12-15)
La estructura del polisacárido capsular S. Fredii HH103 se ha determiando mediante la utilización de las técnicas avanzadas de determinación estructural; electroforesis en geles de poliacrilamida, cromatografía de ...

Gene Replacement and Fluorescent Labeling to Study the Functional Role of Exopolysaccharides in Bifidobacterium animalis subsp. lactis
(Frontiers Media, 2017)
An extracellular layer of exopolysaccharides (EPS) covers the surface of some Bifidobacterium animalis subsp. lactis strains, which could be of relevance for its probiotic performance. In order to understand the functional ...

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 ...

Structure of the unusual Sinorhizobium fredii HH103 lipopolysaccharide and its role in symbiosis
(Elsevier, 2020)
Rhizobia are soil bacteria that form important symbiotic associations with legumes, and rhizobial surface polysaccharides, such as K-antigen polysaccharide (KPS) and lipopolysaccharide (LPS), might be important for symbiosis. ...

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 ...
Tesis Doctoral
Cuantificación de hormonas vegetales y estudio metabolómico mediante cromatografia-espectrometría de masas de alta resolución. Aplicación a la interacción alfalfa-PGPR
(2024-02-23)
La existencia de interacciones beneficiosas entre las bacterias presentes en el suelo y las plantas se conoce desde hace más de un siglo y está firmemente contrastada en diversos tipos de cultivos. Estas interacciones ...
