Bacillus velezensis is a novel biocontrol species exhibiting several mechanisms in biological control of plant pathogens, including antibiosis, production other types antimicrobials, such as volatile organic compounds, direct competition for nutrients and growth space, induction immunity towards pathogens. The aim this study was to assess the potential IP22, cultivated on optimized medium with ...

Scientific name: Xanthomonas axonopodis pv. allii (Roumagnac et al., 2004a,b). Synonyms: Xanthomonas campestris pv. allii (Kadota et al., 2000). Taxonomic position: Proteobacteria: Gammapropteobacteria: Xanthomonadales: Xanthomonasdaceae. Common names: Xanthomonas axonopodis pv. allii is the causal agent of onion bacterial blight (syn. Xanthomonas leaf blight of onion). EPPO code: XANTAA. Phyto...

We present draft genome sequences for three strains of Xanthomonas species, each of which was associated with banana plants (Musa species) but is not closely related to the previously sequenced banana-pathogen Xanthomonas campestris pathovar musacearum. Strain NCPPB4393 had been deposited as Xanthomonas campestris pathovar musacearum but in fact falls within the species Xanthomonas sacchari. St...

Xanthomonas vesicatoria, Xanthomonas euvesicatoria, and Xanthomonas gardneri cause bacterial spot disease. Copper has been applied since the 1920s as part of integrated management programs. The first copper-resistant strains were reported some decades later. Here, we fully sequenced six Xanthomonas strains pathogenic to tomato and/or pepper and having a copper-resistant phenotype.

It is well known that the type III secretion system (T3SS) and type III (T3) effectors are essential for the pathogenicity of most bacterial phytopathogens and that the expression of T3SS and T3 effectors is suppressed in rich media but induced in minimal media and plants. To facilitate in-depth studies on T3SS and T3 effectors, it is crucial to establish a medium for T3 effector expression and...

Single-molecule real-time (SMRT) sequencing allows identification of methylated DNA bases and methylation patterns/motifs at the genome level. Using SMRT sequencing, diverse bacterial methylomes including those of Helicobacter pylori, Lactobacillus spp., and Escherichia coli have been determined, and previously unreported DNA methylation motifs have been identified. However, the methylomes of X...
