Caracterización de genes de Rhizobium tropici CIAT 899 implicados en la biosíntesis de los factores de nodulación independiente de la activación por flavonoides e inducidos por estrés osmótico
(2019-06-19)
En el establecimiento de la simbiosis rizobio-leguminosa, los flavonoides secretados por las raíces activan un regulador transcripcional (proteína NodD) que por unión a unas secuencias promotoras conservadas en los rizobios ...

The Rhizobium tropici CIAT 899 NodD2 protein promotes symbiosis and extends rhizobial nodulation range by constitutive nodulation factor synthesis
(Oxford University Press, 2022)
In the symbiotic associations between rhizobia and legumes, the NodD regulators orchestrate the transcription of the specifc nodulation genes. This set of genes is involved in the synthesis of nodulation factors, which ...

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, ...

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 ...

A Complex Regulatory Network Governs the Expression of Symbiotic Genes in Sinorhizobium Fredii HH103
(Frontiers Media, 2023)
Introduction: The establishment of the rhizobium-legume nitrogen-fixing symbiosis relies on the interchange of molecular signals between the two symbionts. We have previously studied by RNA-seq the effect of the symbiotic ...

Non-Ionic Osmotic Stress Induces the Biosynthesis of Nodulation Factors and Affects Other Symbiotic Traits in Sinorhizobium fredii HH103
(MDPI, 2023)
Simple Summary: Rhizobia are soil proteobacteria able to establish nitrogen-fixing symbiosis with host legumes. This symbiotic interaction, which is highly important from ecological and agronomical points of view since it ...

Las proteínas Nop de Sinorhizobium fredii HH103: Regulación e implicación en la simbiosis con la soja (Glycine max [L.] Merrill)
(2008-04-18)
En los últimos años se ha demostrado que las proteínas secretadas a través del sistema de secreción de tipo III de Sinorhizobium fredii HH103 juegan un papel importante en el establecimiento de una simbiosis efectiva con ...

Regulation and symbiotic significance of nodulation outer proteins secretion in Sinorhizobium fredii HH103
(2008)
In this work we show that the Sinorhizobium fredii HH103 ttsI gene is essential for the expression of the tts genes and secretion of nodulation outer proteins (Nops). Moreover, we demonstrate for the first time, to our ...

NolR Regulates Diverse Symbiotic Signals of Sinorhizobium fredii HH103
(The American Phytopathological Society, 2004)
We have investigated in Sinorhizobium fredii HH103-1 (=HH103 Strr ) the influence of the nolR gene on the production of three different bacterial symbiotic signals: Nod factors, signal responsive (SR) proteins, and ...
