The Rhizobial Type 3 Secretion System: The Dr. Jekyll and Mr. Hyde in the Rhizobium–Legume Symbiosis
(Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Rhizobia are soil bacteria that can establish a symbiotic association with legumes. As a result, plant nodules are formed on the roots of the host plants where rhizobia differentiate to bacteroids capable of fixing atmospheric ...
Tesis Doctoral
Contribución al estudio de los plásmidos de Rhizobium
(1988)
En este trabajo, hemos estudiado la transferencia y expresión del plásmido simbiótico PJB5JI de Rhizobium leguminosarum biovar viceae en diversas estirpes de Rhizobium sp. y Bradyrhizobium sp. que nodulan en Cicer arietinum ...

Sinorhizobium fredii HH103 RirA is required for oxidative stress resistance and efficient symbiosis with Soybean
(MDPI, 2019-02-12)
Members of Rhizobiaceae contain a homologue of the iron-responsive regulatory protein RirA. In different bacteria, RirA acts as a repressor of iron uptake systems under iron-replete conditions and contributes to ameliorate ...

NopC is a rhizobium-specific type 3 secretion system effector secreted by sinorhizobium (ensifer) fredii HH103
(Public Library of Science, 2015)
Sinorhizobium (Ensifer) fredii HH103 is a broad host-range nitrogen-fixing bacterium able to nodulate many legumes, including soybean. In several rhizobia, root nodulation is influenced by proteins secreted through the ...

Sinorhizobium meliloti DnaJ Is Required for Surface Motility, Stress Tolerance, and for Efficient Nodulation and Symbiotic Nitrogen Fixation
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Bacterial surface motility is a complex microbial trait that contributes to host colonization. However, the knowledge about regulatory mechanisms that control surface translocation in rhizobia and their role in the ...
Tesis Doctoral
Estudio del plásmido simbiótico de una estirpe de Rhizobium SP (Hedysarum Coronarium)
(1988)
La estirpe IS 123 de Rhizobium sp. (Hedysarum coronarium) presenta un plásmido simbiótico (230 MD), que se ha marcado con el transposon IN5MOB, comprobándose que es autotransferible, si bien su transferencia a determinadas ...

Biotechnological potential of rhizobial metabolites to enhance the performance of Bradyrhizobium spp. and Azospirillum brasilense inoculants with soybean and maize
(Springer open, 2013)
Agricultural sustainability may represent the greatest encumbrance to increasing food production. On the other hand, as a component of sustainability, replacement of chemical fertilizers by bio-fertilizers has the potential ...

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 ...
