Journal ArticleDOI
Methylotrophic Methylobacterium bacteria nodulate and fix nitrogen in symbiosis with legumes.
Abdourahmane Sy,Eric Giraud,Philippe Jourand,Nelly Garcia,Anne Willems,Philippe de Lajudie,Yves Prin,Marc Neyra,Monique Gillis,Catherine Boivin-Masson,Bernard Dreyfus +10 more
TL;DR: The discovery of a fourth rhizobial branch involving bacteria of the Methylobacterium genus is reported, which is closely related to Bradyrhizobium NodA, suggesting that this gene was acquired by horizontal gene transfer.
Journal ArticleDOI
Polyphasic Taxonomy of Rhizobia: Emendation of the Genus Sinorhizobium and Description of Sinorhizobium meliloti comb. nov., Sinorhizobium saheli sp. nov., and Sinorhizobium teranga sp. nov.
Philippe de Lajudie,Anne Willems,Bruno Pot,Dirk Dewettinck,Gloria M. Maestrojuan,Marc Neyra,Matthew D. Collins,Bernard Dreyfus,Karel Kersters,Monique Gillis +9 more
TL;DR: Two of the clusters identified on the basis of SDS-PAGE data are genotypically and phenotypically distinct groups that belong on the Rhizobium meliloti-RhZobium fredii rRNA branch and contains strains isolated in Africa, in Brazil, and in New Zealand from different leguminous species.
Journal ArticleDOI
Photosynthetic bradyrhizobia are natural endophytes of the African wild rice Oryza breviligulata.
Clémence Chaintreuil,Eric Giraud,Yves Prin,Jean Lorquin,Amadou Moustapha Bâ,Monique Gillis,Philippe de Lajudie,Bernard Dreyfus +7 more
TL;DR: The discovery that photosynthetic Bradyrhizobium strains, which are usually known to induce nitrogen-fixing nodules on stems of the legume Aeschynomene, are also natural true endophytes of the primitive rice O. breviligulatacould significantly enhance cultivated rice production is found.
Journal ArticleDOI
Methylobacterium nodulans sp nov., for a group of aerobic, facultatively methylotrophic, legume root-nodule-forming and nitrogen-fixing bacteria
Philippe Jourand,Eric Giraud,Gilles Béna,Abdoulaye Sy,Anne Willems,Monique Gillis,Bernard Dreyfus,Philippe de Lajudie +7 more
TL;DR: The present study includes additional genotypic and phenotypic characterization of this novel Methylobacterium species, i.e. nifH gene sequence, morphology, physiology, enzymic and carbon source assimilation tests and antibiotic resistance.
Journal ArticleDOI
Phylogeny of the Rhizobium-Allorhizobium-Agrobacterium clade supports the delineation of Neorhizobium gen. nov.
Seyed Abdollah Mousavi,Janina Österman,Niklas Wahlberg,Xavier Nesme,Céline Lavire,Ludovic Vial,Lars Paulin,Philippe de Lajudie,Kristina Lindström +8 more
TL;DR: A phylogenetic study showed that the taxonomic status of several taxa could be resolved by the creation of more novel genera, and indicated that the name Neorhizobium is proposed for a new genus.
