A high-molecular-weight outer membrane protein of Xanthomonas oryzae pv. oryzae exhibits similarity to non-fimbrial adhesins of animal pathogenic bacteria and is required for optimum virulence
Transposon insertions in a novel 3.798 kb open reading frame (ORF) of the rice pathogen, Xanthomonas oryzae pv. oryzae (Xoo) cause virulence deficiency and altered colony/lawn morphology. This ORF ...
Bacteriocins from plant pathogenic bacteria
Many bacteria produce antimicrobial substances such as nonribosomally synthesized antibiotics and ribosomally synthesized proteinaceous compounds referred to as bacteriocins. Secretion of antimicro...
Comparative genomic analysis of coffee-infecting Xylella fastidiosa strains isolated from Brazil
Strains of Xylella fastidiosa constitute a complex group of bacteria that develop within the xylem of many plant hosts, causing diseases of significant economic importance, such as Pierce's disease...
Diffusible signal factor-dependent quorum sensing in pathogenic bacteria and its exploitation for disease control
Cell-to-cell signals of the diffusible signal factor (DSF) family are cis-2-unsaturated fatty acids of differing chain length and branching pattern. DSF signalling has been described in diverse bac...
Estimation of the economic impact of Xylella fastidiosa in Aragon
The appearance of Xylella fastidiosa in 2017 in the Iberian Peninsula has caused growing concern in regions such as Aragon, with a large area of crops sensitive to bacteria and of great economic im...
Genomic comparison of the endophyte Herbaspirillum seropedicae SmR1 and the phytopathogen Herbaspirillum rubrisubalbicans M1 by suppressive subtractive hybridization and partial genome sequencing
Herbaspirillum rubrisubalbicans M1 causes the mottled stripe disease in sugarcane cv. B-4362. Inoculation of this cultivar with Herbaspirillum seropedicae SmR1 does not produce disease symptoms. A ...
Grape Cultivar and Sap Culture Conditions Affect the Development of Xylella fastidiosa Phenotypes Associated with Pierce's Disease
Xylella fastidiosa is a xylem-limited bacterium in plant hosts and causes Pierce's disease (PD) of grapevines, which differ in susceptibility according to the Vitis species (spp.). In this work we ...
Harnessing Host-Vector Microbiome for Sustainable Plant Disease Management of Phloem-Limited Bacteria
Plant health and productivity is strongly influenced by their intimate interaction with deleterious and beneficial organisms, including microbes, and insects. Of the various plant diseases, insect-...
HecA, a member of a class of adhesins produced by diverse pathogenic bacteria, contributes to the attachment,, aggregation, epidermal cell killing, and virulence phenotypes of Erwinia chrysanthemi EC16 on Nicotiana clevelandii seedlings
Erwinia chrysanthemi is representative of a broad class of bacterial pathogens that are capable of inducing necrosis in plants. The E. chrysanthemi EC16 hecA gene predicts a 3,850-aa member of the ...
High-quality mutant libraries of Xanthomonas oryzae pv. oryzae and X-campestris pv. campestris generated by an efficient transposon mutagenesis system
A novel transposon mutagenesis system for the phytopathogenic bacteria Xanthomonas oryzae pv. oryzae (Xoo) and X campestris pv. campestris (Xcc) was developed using a Tn5-based transposome. A highl...
Identification and analysis of seven effector protein families with different adaptive and evolutionary histories in plant-associated members of the Xanthomonadaceae
The Xanthomonadaceae family consists of species of non-pathogenic and pathogenic gamma-proteobacteria that infect different hosts, including humans and plants. In this study, we performed a compara...
Insects as alternative hosts for phytopathogenic bacteria
Phytopathogens have evolved specialized pathogenicity determinants that enable them to colonize their specific plant hosts and cause disease, but their intimate associations with plants also predis...
