Journal ArticleDOI
Phenotypic Selection and Phase Variation Occur during Alfalfa Root Colonization by Pseudomonas fluorescens F113
María Sánchez-Contreras,María Sánchez-Contreras,Marta Martín,Marta Villacieros,Fergal O'Gara,Ildefonso Bonilla,Rafael Rivilla +6 more
TL;DR: Mutation of the F113 sss gene, encoding a site-specific recombinase, showed that most of the phenotypic variation was due to the activity of this recomb inase, indicating that phase variation occurs during rhizosphere colonization.
Journal ArticleDOI
Polychlorinated Biphenyl Rhizoremediation by Pseudomonas fluorescens F113 Derivatives, Using a Sinorhizobium meliloti nod System To Drive bph Gene Expression
Marta Villacieros,Clare Whelan,Martina Mackova,Jesper Molgaard,María Sánchez-Contreras,Javier Lloret,Daniel Aguirre de Cárcer,Roke I. Oruezabal,Luis Bolaños,Thomas Macek,Ulrich Karlson,David N. Dowling,Marta Martín,Rafael Rivilla +13 more
TL;DR: A high-level expression system was designed from rhizobial nod gene regulatory relays and showed that nodbox 4 from Sinorhizobium meliloti has a high level of expression in F113 that is dependent on an intact nodD1 gene.
Journal ArticleDOI
Analysis of Pseudomonas fluorescens F113 genes implicated in flagellar filament synthesis and their role in competitive root colonization.
Silvia Capdevila,Francisco Martínez-Granero,María Sánchez-Contreras,Rafael Rivilla,Marta Martín +4 more
TL;DR: The motility mechanism of the well-known biocontrol strain Pseudomonas fluorescens F113 is analyzed, indicating that the wild-type motility properties are necessary for competitive root colonization and the possibility of improving competitiveRoot colonization by manipulating the motility processes.
Journal ArticleDOI
Comparative genomics of the emerging human pathogen Photorhabdus asymbiotica with the insect pathogen Photorhabdus luminescens
Paul Wilkinson,Nicholas R. Waterfield,Lisa Crossman,Craig Corton,María Sánchez-Contreras,Isabella Vlisidou,Andrew Barron,Alexandra Bignell,Louise Clark,Douglas Ormond,Matthew Mayho,Nathalie Bason,Frances Smith,Mark Simmonds,Carol Churcher,David Harris,Nicholas R Thompson,Michael A. Quail,Julian Parkhill,Richard H. ffrench-Constant +19 more
TL;DR: The results suggest that North American isolates of Pa have acquired virulence against man via the acquisition of a plasmid and specific virulence factors with similarity to those shown to play roles in pathogenicity against humans in other bacteria.
Journal ArticleDOI
Colonization behaviour of Pseudomonas fluorescens and Sinorhizobium meliloti in the alfalfa (Medicago sativa) rhizosphere
Marta Villacieros,Marta Villacieros,Barry Power,María Sánchez-Contreras,Javier Lloret,Roke I. Oruezabal,Marta Martín,Francisca Fernández-Piñas,Ildefonso Bonilla,Clare Whelan,David N. Dowling,Rafael Rivilla +11 more
TL;DR: The results obtained support the possibility of using this bacterium in conjunction with alfalfa for biocontrol or rhizoremediation technologies, and inoculation of F113rif had a deleterious effect on plants grown in gnotobiotic systems, which was reversed by co-inoculation.
