Sinorhizobium fredii HH103 nolR and nodD2 mutants gain capacity for infection thread invasion of Lotus japonicus Gifu and Lotus burttii
(Willey, 2019-03-06)
Sinorhizobium fredii HH103 RifR, a broad-host-range rhizobial strain, forms ineffective nodules with Lotus japonicus but induces nitrogen-fixing nodules in Lotus burttii roots that are infected by intercellular entry. Here ...

Plant growth promotion in cereal and leguminous agricultural important plants: From microorganism capacities to crop production
(2014)
Plant growth-promoting rhizobacteria (PGPR) are free-living bacteria which actively colonize plant roots, exerting beneficial effects on plant development. The PGPR may (i) promote the plant growth either by using their ...

NrcR, a new transcriptional regulator of rhizobium tropici ciat 899 involved in the legume root-nodule symbiosis
(Public Library of Science, 2016)
The establishment of nitrogen-fixing rhizobium-legume symbioses requires a highly complex cascade of events. In this molecular dialogue the bacterial NodD transcriptional regulators in conjunction with plant inducers, ...

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 ...

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 ...

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 ...

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 ...

RNA-seq analysis of the Rhizobium tropici CIAT 899 transcriptome shows similarities in the activation patterns of symbiotic genes in the presence of apigenin and salt
(BioMed Central, 2016)
Background Rhizobium tropici strain CIAT 899 establishes effective symbioses with several legume species, including Phaseolus vulgaris and Leucaena leucocephala. This bacterium synthesizes a large variety of nodulation ...

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 ...

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 ...
