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
Novel demonstration of RNAi in citrus reveals importance of citrus callose synthase in defence against Xanthomonas citri subsp. citri.
Ramón Atanasio Enrique,Florencia Siciliano,María Alejandra Favaro,Nadia Gerhardt,Roxana Andrea Roeschlin,Luciano A. Rigano,Lorena Noelia Sendín,Atilio Pedro Castagnaro,Adrián Alberto Vojnov,María Rosa Marano +9 more
TL;DR: This study demonstrates the efficacy of RNA interference (RNAi) as a functional genomics tool to assess the function of candidate genes involved in the defence response of Citrus limon against the citrus canker pathogen and demonstrates that high-throughput reverse genetic analysis is feasible in citrus.
Journal ArticleDOI
XbmR, a new transcription factor involved in the regulation of chemotaxis, biofilm formation and virulence in Xanthomonas citri subsp. citri
Pablo Marcelo Yaryura,Valeria Paola Conforte,Florencia Malamud,Roxana Andrea Roeschlin,Verónica De Pino,Atilio Pedro Castagnaro,Yvonne McCarthy,J. Maxwell Dow,María Rosa Marano,Adrián Alberto Vojnov +9 more
TL;DR: It is shown that mutation of XAC3733 resulted in impaired structural development of the Xcc biofilm, loss of chemotaxis and reduced virulence in grapefruit plants, suggesting that XbmR is a key regulator of flagellar-dependent motility and Chemotaxis exerting its action through a regulatory pathway that involves FliA and c-di-GMP.
Journal ArticleDOI
Xanthan Pyruvilation Is Essential for the Virulence of Xanthomonas campestris pv. campestris.
María Isabel Bianco,Laila Toum,Pablo Marcelo Yaryura,Natalia Mielnichuk,Gustavo Eduardo Gudesblat,Gustavo Eduardo Gudesblat,Roxana Andrea Roeschlin,María Rosa Marano,Luis Ielpi,Adrián Alberto Vojnov +9 more
TL;DR: It is observed that the presence of the external mannose residues and, hence, pyruvilation is required for xanthan to suppress callose deposition as well as to interfere with stomatal defense, which seems to be essential for XanthomonasCampestris pv.
Journal ArticleDOI
Surface barriers of mandarin 'okitsu' leaves make a major contribution to canker disease resistance.
María Alejandra Favaro,Norma Micheloud,Roxana Andrea Roeschlin,Maria Amalia Chiesa,Atilio Pedro Castagnaro,Adrián Alberto Vojnov,Frederick G. Gmitter,José Gadea,Luis M. Rista,Norberto Gariglio,María Rosa Marano +10 more
TL;DR: It is shown that 'Okitsu' leaves are nevertheless susceptible to X. citri infection during a period of their development; however, this period is shorter than that seen in the susceptible mandarin 'Clemenules' (C. clementina).
