Journal ArticleDOI
The Xanthomonas axonopodis pv. citri flagellum is required for mature biofilm and canker development.
Florencia Malamud,Pablo S. Torres,Roxana Andrea Roeschlin,Luciano A. Rigano,Ramón Atanasio Enrique,Hernán Ruy Bonomi,Atilio Pedro Castagnaro,María Rosa Marano,Adrián Alberto Vojnov +8 more
TL;DR: Confocal laser scanning microscopy of biofilms produced in static culture demonstrated that the flagellum is also involved in the formation of mushroom-shaped structures and water channels, and in the dispersion ofBiofilms, indicating a regulatory role for DSF in both types of motility.
Journal ArticleDOI
Controlled synthesis of the DSF cell–cell signal is required for biofilm formation and virulence in Xanthomonas campestris
Pablo S. Torres,Florencia Malamud,Luciano A. Rigano,Daniela Marta Russo,María Rosa Marano,Atilio Pedro Castagnaro,Angeles Zorreguieta,Kamal Bouarab,John Maxwell Dow,Adrián Alberto Vojnov +9 more
TL;DR: Findings suggest that DSF signalling is finely balanced during both biofilm formation and virulence of the black rot pathogen Xanthomonas campestris.
Journal ArticleDOI
Bacterial Cyclic β-(1,2)-Glucan Acts in Systemic Suppression of Plant Immune Responses
Luciano A. Rigano,Caroline Payette,Geneviève Brouillard,María Rosa Marano,Laura Abramowicz,Pablo S. Torres,Maximina H. Yun,Atilio Pedro Castagnaro,Mohamed El Oirdi,Vanessa Dufour,Florencia Malamud,John Maxwell Dow,Kamal Bouarab,Adrián Alberto Vojnov +13 more
TL;DR: Systemic suppression is a novel counterdefensive strategy that may facilitate pathogen spread in plants and may have important implications for the understanding of plant–pathogen coevolution and for the development of phytoprotection measures.
Journal ArticleDOI
Structure of the Full-Length Bacteriophytochrome from the Plant Pathogen Xanthomonas campestris Provides Clues to its Long-Range Signaling Mechanism.
Lisandro H. Otero,Sebastián Klinke,Jimena Rinaldi,Francisco Velazquez-Escobar,Maria Andrea Mroginski,Maria Fernandez Lopez,Florencia Malamud,Adrián Alberto Vojnov,Peter Hildebrandt,Fernando Alberto Goldbaum,Hernán Ruy Bonomi +10 more
TL;DR: Structural analyses suggest that the photoconversion between the Pr and Pfr states in the full-length XccBphP may involve changes in the relative positioning of the output module, contributing to understand the light-induced structural changes propagated from the photosensor to the output modules in phytochrome signaling.
Journal ArticleDOI
Identification and characterization of biofilm formation-defective mutants of Xanthomonas citri subsp. citri.
Florencia Malamud,Rafael Augusto Homem,Valeria Paola Conforte,Pablo Marcelo Yaryura,Atilio Pedro Castagnaro,María Rosa Marano,Alexandre Morais do Amaral,Adrián Alberto Vojnov +7 more
TL;DR: The analysis of the 23 mutants not only revealed the involvement of new genes in biofilm formation, but also reinforced the importance of exopolysaccharide production, motility and cell surface structures in this process.
