      A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes  [Article]

      Crespo Rivas, Juan Carlos; Margaret Oliver, Isabel María; Pérez Montaño, Francisco de Asís; López Baena, Francisco Javier; Vinardell González, José María; Ollero Márquez, Francisco Javier; Moreno Onorato, Francisco Javier; Ruiz Sainz, José Enrique; Buendía Clavería, Ana María (Sociedad Española de Microbiología. Viguera Editores, 2007)
      Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media. The mutated gene, pyrF, codes for an ...

      Structure and biological roles of Sinorhizobium fredii HH103 exopolysaccharide  [Article]

      Rodríguez Navarro, Dulce Nombre; Rodríguez Carvajal, Miguel Ángel; Acosta Jurado, Sebastián; Soto Misffut, María José; Margaret Oliver, Isabel María; Crespo Rivas, Juan Carlos; Sanjuan, Juan; Temprano Vera, Francisco Jesús; Gil Serrano, Antonio Miguel; Ruiz Sainz, José Enrique; Vinardell González, José María (Public Library of Science, 2014)
      Here we report that the structure of the Sinorhizobium fredii HH103 exopolysaccharide (EPS) is composed of glucose, galactose, glucuronic acid, pyruvic acid, in the ratios 5:2:2:1 and is partially acetylated. A S. fredii ...

      The rkpU gene of Sinorhizobium fredii HH103 is required for bacterial K-antigen polysaccharide production and for efficient nodulation with soybean but not with cowpea  [Article]

      Hidalgo Perea, Ángeles; Margaret Oliver, Isabel María; Crespo Rivas, Juan Carlos; Parada Ibáñez, Maribel Eugenia; Murdoch, Piedad del Socorro; López, Abigail; Buendía Clavería, Ana María; Moreno Onorato, Francisco Javier; Gil Serrano, Antonio Miguel; Rodríguez Carvajal, Miguel Ángel; Ruiz Sainz, José Enrique; Vinardell González, José María (Society for General Microbiology, 2010)
      In this work, the role of the rkpU and rkpJ genes in the production of the K-antigen polysaccharides (KPS) and in the symbiotic capacity of Sinorhizobium fredii HH103, a broad host-range rhizobial strain able to nodulate ...
