Journal ArticleDOI
Isolation, taxonomic analysis, and phenotypic characterization of bacterial endophytes present in alfalfa (Medicago sativa) seeds
José Luis López,Florencia Alvarez,Analía Príncipe,Maria Salas,Mauricio Javier Lozano,Walter Omar Draghi,Edgardo Jofré,Antonio Lagares +7 more
TL;DR: This work has investigated the type of culturable endophytic bacteria that are carried within surface-sterilized alfalfa seeds and found isolates with complex combinations of traits that, upon a Principal-Component-Analysis, could be classified into four phenotypic groups.
Journal ArticleDOI
Specificity traits consistent with legume-rhizobia coevolution displayed by Ensifer meliloti rhizosphere colonization
Maria Salas,Mauricio Javier Lozano,José Luis López,Walter Omar Draghi,Javier Serrania,Gonzalo Arturo Torres Tejerizo,Francisco Javier Albicoro,Juliet F. Nilsson,Mariano Pistorio,María Florencia Del Papa,Gustavo Parisi,Anke Becker,Antonio Lagares +12 more
TL;DR: The results suggest that consolidation of E. meliloti into its current symbiotic state should have occurred in a rhizobacterium that had already been adapted to rhizospheres of the Trifoliae tribe, and identified a subset of genes that impacted more severely the colonization of the roots of alfalfa than of pea.
Journal ArticleDOI
A consolidated analysis of the physiologic and molecular responses induced under acid stress in the legume-symbiont model-soil bacterium Sinorhizobium meliloti.
Walter Omar Draghi,M. F. Del Papa,C. Hellweg,Steven Alexander Watt,Tony Francis Watt,Aiko Barsch,Mauricio Javier Lozano,Antonio Lagares,Maria Salas,José Luis López,Francisco Javier Albicoro,Juliet F. Nilsson,G.A. Torres Tejerizo,María Flavia Luna,Mariano Pistorio,José Luis Boiardi,Alfred Pühler,Stefan Weidner,Karsten Niehaus +18 more
TL;DR: Multivariate analysis of global metabolome data served to unequivocally correlate specific-metabolite profiles with the extracellular pH, showing that at low pH the pentose-phosphate pathway exhibited increases in several transcripts, enzymes, and metabolites.
Journal ArticleDOI
Conjugal properties of the Sinorhizobium meliloti plasmid mobilome.
Mariano Pistorio,MarÃa A. Giusti,MarÃa F. Del Papa,Walter Omar Draghi,Mauricio Javier Lozano,Gonzalo Arturo Torres Tejerizo,Antonio Lagares +6 more
TL;DR: A widespread compatibility among the conjugal functions of the cryptic plasmids in S. meliloti is revealed, and this fact, together with the observed high proportion of existing donor genotypes, points to the extrachromosomal compartment of the species as being an extremely active plasmid mobilome.
Journal ArticleDOI
Genetic and functional characterization of a yet-unclassified rhizobial Dtr (DNA-transfer-and-replication) region from a ubiquitous plasmid conjugal system present in Sinorhizobium meliloti, in Sinorhizobium medicae, and in other nonrhizobial Gram-negative bacteria
María de los Ángeles Giusti,Mariano Pistorio,Mauricio Javier Lozano,Gonzalo Arturo Torres Tejerizo,Maria Salas,María Carla Martini,José Luis López,Walter Omar Draghi,María Florencia Del Papa,Daniel Pérez-Mendoza,Juan Sanjuán,Antonio Lagares +11 more
TL;DR: An as-yet-unclassified and seemingly ubiquitous conjugal system that provides a mechanistic support for the HGT between sympatric rhizobia of Medicago roots, and between other soil and rhizospheric bacteria.
