Xanthomonas oryzae pv. causes bacterial blight of rice (Oryza sativa L.), a major disease that constrains production this staple crop in many parts the world. We report here on complete genome sequence strain PXO99A and its comparison to two previously sequenced strains, KACC10331 MAFF311018, which are highly similar one another.The is single circular chromosome 5,240,075 bp, considerably longer than genomes other strains (4,941,439 bp 4,940,217 respectively), it contains 5083 protein-coding...
TonB-dependent receptors (TBDRs) are outer membrane proteins mainly known for the active transport of iron siderophore complexes in Gram-negative bacteria. Analysis genome phytopathogenic bacterium Xanthomonas campestris pv. (Xcc), predicts 72 TBDRs. Such an overrepresentation is common species but limited to only a small number Here, we show that one Xcc TBDR transports sucrose with very high affinity, suggesting it might be scavenger. This acts inner transporter, amylosucrase and regulator...
ABSTRACT Xanthomonas is a large genus of bacteria that collectively cause disease on more than 300 plant species. The broad host range the contrasts with stringent and tissue specificity for individual species pathovars. Whole-genome sequences campestris pv. raphani strain 756C X. oryzae oryzicola BLS256, pathogens infect mesophyll leading models biology, Arabidopsis thaliana rice, respectively, were determined provided insight into genetic determinants specificity. Comparisons made genomes...
Abstract Motivation As pan-genome approaches are largely employed for bacterial comparative genomics and evolution analyses, but still difficult to be carried out by non-bioinformatician biologists, there is a need an innovative tool facilitating the exploration of pan-genomes. Results PanExplorer web application providing various genomic analyses reports, giving intuitive views that enable better understanding example, we produced 121 Anaplasmataceae strains (including 30 Ehrlichia, 15...
'Candidatus Liberibacter solanacearum' (Lso) has emerged as a serious threat world-wide. Five Lso haplotypes have been identified so far. Haplotypes A and B are present in the Americas and/or New Zealand, where they vectored to solanaceous plants by potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae). The fastidious nature of these pathogens hindered study interactions with their eukaryotic hosts (vector plant). To understand strategies used infect vector, effects each...
Understanding the survival, multiplication, and transmission to seeds of plant pathogenic bacteria is central study their pathogenesis. We hypothesized that type III secretion system (T3SS), encoded by hrp genes, could have a role in host colonization bacteria. The seed-borne pathogen Xanthomonas fuscans subsp. causes common bacterial blight bean (Phaseolus vulgaris). Directed mutagenesis strain CFBP4834-R X. population density monitoring on leaves showed strains with mutations regulatory...
Type IV effectors (T4Es) are proteins produced by pathogenic bacteria to manipulate host cell gene expression and processes, divert the machinery for their own profit circumvent immune responses. T4Es have been characterized some but many remain be discovered. To help biologists identify putative from complete genome of α- γ-proteobacteria, we developed a Perl-based command line bioinformatics tool called S4TE (searching algorithm type-IV secretion system effectors). The predicts ranks T4E...
SUMMARY The cruciferous weed Arabidopsis thaliana and the causal agent of black rot disease Crucifers Xanthomonas campestris pv. ( Xcc ) are both model organisms in plant pathology. Their interaction has been studied successfully past, but these investigations suffered from high variability. In present study, we describe an improved Arabidopsis– pathosystem that is based on a wound inoculation procedure. We show after inoculation, colonizes vascular system leaves causes typical symptoms...
Summary Ralstonia solanacearum is a plant pathogenic bacterium that undergoes spontaneous phenotypic conversion (PC) from wild‐type to non‐pathogenic form. PC often associated with mutations in phcA, which key virulence regulatory gene. Until now, reversion the form has not been observed for variants and biological significance of questioned. In this study, we characterized various alterations phcA (eight IS element insertions, three tandem duplications, seven deletions base substitution) 19...
A new bacterial disease of Persian (English) walnut ( Juglans regia ) has been observed in France. This disease, called vertical oozing canker (VOC), is characterized by cankers on trunks and branches affected trees with exudates. To determine the aetiology a study was carried out 79 orchards nurseries located southeastern southwestern Bacterial analysis from diseased samples yielded 36 strains identified as Xanthomonas arboricola 32 Brenneria nigrifluens basis biochemical tests. The causal...
Anaplasma phagocytophilum is an emerging zoonotic pathogen transmitted by Ixodes scapularis that causes human granulocytic anaplasmosis. Here, a high throughput quantitative proteomics approach was used to characterize A. proteome during rickettsial multiplication and identify proteins involved in infection of the tick vector, I. scapularis. The first step this research focused on cells infected with sampled at two time points containing 10–15% 65–71% cells, respectively key bacterial...
Bacterial pathogens have evolved numerous strategies to corrupt, hijack or mimic cellular processes in order survive and proliferate. Among those strategies, Type IV effectors (T4Es) are proteins secreted by pathogenic bacteria manipulate host cell during infection. They delivered into eukaryotic cells an ATP-dependent manner via the type secretion system, a specialized multiprotein complex. T4Es contain wide spectrum of features including eukaryotic-like domains, localization signals...
Protein structure and protein-protein interaction (PPI) predictions based on coevolution have transformed structural biology, but managing pre-processing post-processing can be complex time-consuming, making these tools less accessible. Here, we introduce PPIFold, a pipeline built the AlphaPulldown Python package, designed to automate file handling streamline generation of outputs, facilitating interpretation PPI prediction results. The was validated bacterial Type 4 Secretion System...
Ticks are ectoparasites that feed on the blood of animals and humans among arthropods responsible for numerous human animal diseases worldwide. The tropical bont tick, Amblyomma variegatum, is a significant natural vector Ehrlichia ruminantium, causative agent heartwater. This disease endemic in many countries, including those sub-Saharan Africa certain Caribbean islands. Due to potential heartwater its pose an economic health threats non-endemic regions, they have been designated as...
Ralstonia solanacearum GMI1000 is a gram-negative plant pathogen which contains an hrp gene cluster codes for type III protein secretion system (TTSS). We identified two novel Hrp-secreted proteins, called PopF1 and PopF2, display similarity to one another putative TTSS translocators, HrpF NopX, from Xanthomonas spp. rhizobia, respectively. They also show similarities with translocators of the YopB family animal-pathogenic bacteria. Both popF1 popF2 belong HrpB regulon are required...
The disease, Heartwater, caused by the Anaplasmataceae E. ruminantium, represents a major problem for tropical livestock and wild ruminants. Up to now, no effective vaccine has been available due limited cross protection of vaccinal strains on field high genetic diversity ruminantium within geographical locations. To address this issue, we inferred population structure 194 isolates circulating worldwide using Multilocus Sequence Typing based lipA, lipB, secY, sodB sucA genes. Phylogenetic...
