Journal ArticleDOI
The dual nature of trehalose in citrus canker disease: a virulence factor for Xanthomonas citri subsp. citri and a trigger for plant defence responses.
Ainelén Piazza,Tamara Zimaro,Betiana S. Garavaglia,Florencia A. Ficarra,Ludivine Thomas,Claudius Marondedze,Regina Feil,John E. Lunn,Chris Gehring,Jorgelina Ottado,Natalia Gottig +10 more
TL;DR: Trehalose is a double-edged sword for both partners in the citrus–Xanthomonas interaction, as it is necessary for bacterial survival but also triggers citrus defence responses.
Journal ArticleDOI
The type III protein secretion system contributes to Xanthomonas citri subsp. citri biofilm formation.
Tamara Zimaro,Ludivine Thomas,Claudius Marondedze,Germán G. Sgro,Cecilia Garofalo,Florencia A. Ficarra,Christoph A Gehring,Jorgelina Ottado,Natalia Gottig +8 more
TL;DR: A novel role for T3SS in X. citri in the modulation of biofilm formation is indicated, which causes changes in the expression of proteins involved in metabolic processes, energy generation, exopolysaccharide production and bacterial motility as well as outer membrane proteins.
Journal ArticleDOI
Contribution of a harpin protein from Xanthomonas axonopodis pv. citri to pathogen virulence.
Germán G. Sgro,Florencia A. Ficarra,German Dunger,Telma E. Scarpeci,Estela M. Valle,Adriana Cortadi,Elena G. Orellano,Natalia Gottig,Jorgelina Ottado +8 more
TL;DR: The results suggest that, even though Hpa1 elicits the defence response in nonhost plants and, to a lesser extent, in host plants, its main roles in citrus canker are to alter leaf mesophyll structure and to aggregate bacterial cells, and thus increase virulence and pathogen fitness.
Journal ArticleDOI
Structural insights into bacterial resistance to cerulenin.
Felipe Trajtenberg,Silvia Altabe,Nicole Larrieux,Florencia A. Ficarra,Diego de Mendoza,Alejandro Buschiazzo,Gustavo E. Schujman +6 more
TL;DR: Light is shed on the mechanisms of FabF catalysis and resistance to cerulenin, and it is demonstrated that the E. coli modified enzyme efficiently catalyzes the synthesis of medium and long‐chain ketoacyl‐ACPs.
Journal ArticleDOI
Bacterial and plant natriuretic peptides improve plant defence responses against pathogens.
Florencia A. Ficarra,Carolina Grandellis,Betiana S. Garavaglia,Natalia Gottig,Jorgelina Ottado +4 more
TL;DR: Plant over-expressing XacPNP or AtPNP-A were more resistant to Pst infection than control plants, whereas PNP-deficient plants were more susceptible and showed a stronger hypersensitive response when challenged with non-host bacteria.
