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 ...

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 ...

Knock-down of phosphoenolpyruvate carboxylase 3 negatively impacts growth, productivity, and responses to salt stress in sorghum (Sorghum bicolor L.)
(Wiley, 2022)
Phosphoenolpyruvate carboxylase (PEPC) is a carboxylating enzyme with important roles in plant metabo-lism. Most studies in C4plants have focused on photosynthetic PEPC, but less is known about non-photosynthetic PEPC ...

Membrane vesicle engineering with “à la carte” bacterial-immunogenic molecules for organism-free plant vaccination
(Wiley-Blackwell, 2023)
The United Nations heralds a world population exponential increase exceeding 9.7 billion by 2050. This poses the challenge of covering the nutritional needs of an overpopulated world by the hand of preserving the environment. ...

OnfD, an AraC-Type Transcriptional Regulator Encoded by Rhizobium tropici CIAT 899 and Involved in Nod Factor Synthesis and Symbiosis
(American Society for Microbiology, 2020)
Rhizobium tropici CIAT 899 is a broad-host-range rhizobial strain that establishes symbiotic interactions with legumes and tolerates different environmental stresses such as heat, acidity, or salinity. This rhizobial strain ...

The Sinorhizobium fredii HH103 type III secretion system effector NopC blocks nodulation with Lotus japonicus Gifu
(Oxford, 2020-06-26)
Results GunA from S. fredii HH103 shows cellulase activity and is secreted through the T3SS in response to the inducer flavonoid genistein. Interestingly, at the beggining of the symbiotic process, GunA was partially ...

Proposed research for innovative solutions for chickpeas and beans in a climate change scenario: The Mediterranean basin
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
In order to gain insight into the complex molecular networks driving legume adaptation caused by climate change, it is necessary to deeply characterize the existing germplasm in response to the environmental constraint ...

Show me your secret(ed) weapons: a multifaceted approach reveals a wide arsenal of type III‐secreted effectors in the cucurbit pathogenic bacterium Acidovorax citrulli and novel effectors in the Acidovorax genus
(Wiley, 2020)
The cucurbit pathogenic bacterium Acidovorax citrulli requires a functional type III secretion system (T3SS) for pathogenicity. In this bacterium, as with Xanthomonas and Ralstonia spp., an AraC-type transcriptional ...
Artículo
Natural variation in a short region of the Acidovorax citrulli type III‐secreted effector AopW1 is associated with differences in cytotoxicity and host adaptation
(Wiley, 2023-10-21)
Bacterial fruit blotch, caused by Acidovorax citrulli, is a serious disease of melon and watermelon. The strains of the pathogen belong to two major genetic groups: group I strains are strongly associated with melon, while ...
