Lipopolysaccharide (LPS) from Burkholderia cepacia is more active than LPS from Pseudomonas aeruginosa and Stenotrophomonas maltophilia in stimulating tumor necrosis factor alpha from human monocytes. (1/578)

Whole cells and lipopolysaccharides (LPSs) extracted from Burkholderia cepacia, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, and Escherichia coli were compared in their ability to stimulate tumor necrosis factor alpha (TNF-alpha) from the human monocyte cell line MonoMac-6. B. cepacia LPS, on a weight-for-weight basis, was found to have TNF-alpha-inducing activity similar to that of LPS from E. coli, which was approximately four- and eightfold greater than the activity of LPSs from P. aeruginosa and S. maltophilia, respectively. The LPS-stimulated TNF-alpha production from monocytes was found to be CD14 dependent. These results suggest that B. cepacia LPS might play a role in the pathogenesis of inflammatory lung disease in cystic fibrosis, and in some patients it might be responsible, at least in part, for the sepsis-like cepacia syndrome.  (+info)

Xf phage invading the host cells with their protein coats. (2/578)

The Xf phage coat protein associated with infected cells could not be removed by washing with antiserum and tris-EDTA buffer. Although the infected cells were consecutively washed 6 times with tris-EDTA buffer, the ratios of parental phage 6H-DNA to 14C-protein were not changed. A considerable amount of the parental 14C-protein and 3H-DNA in the original ratio were detected in the membrane and the soluble cytoplasmic fractions of infected cells. The studies of the change in Xf 14C-protein and 3H-DNA incorporation into the host cells and their release showed that DNA and protein penetrate together into the host cells during the first 60 min after infection (p.i.). While virtually all parental DNA was conserved, re-utilized and released from the infected cell 60 min p.i., no apparent release of parental protein was observed. Approx. 40% of the parental protein became degraded and could be washed from the infected cell after 90 min; the rest of the parental protein remained and probably was re-utilized by the host.  (+info)

AFLP fingerprinting: an efficient technique for detecting genetic variation of Xanthomonas axonopodis pv. manihotis. (3/578)

Xanthomonas axonopodis pv. manihotis (Xam) is the causative agent of cassava bacterial blight (CBB), a worldwide disease that is particularly destructive in South America and Africa. CBB is controlled essentially through the use of resistant varieties. To develop an appropriate disease management strategy, the genetic diversity of the pathogen's populations must be assessed. Until now, the genetic diversity of Xam was characterized by RFLP analyses using ribotyping, and plasmid and genomic Xam probes. We used AFLP (amplified fragment length polymorphism), a novel PCR-based technique, to characterize the genetic diversity of Colombian Xam isolates. Six Xam strains were tested with 65 AFLP primer combinations to identify the best selective primers. Eight primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected between Xam strains. Forty-seven Xam strains, originating from different Colombian ecozones, were analysed with the selected combinations. Results obtained with AFLP are consistent with those obtained with RFLP, using plasmid DNA as a probe. Some primer combinations differentiated Xam strains that were not distinguished by RFLP analyses, thus AFLP fingerprinting allowed a better definition of the genetic relationships between Xam strains.  (+info)

Removal of cadmium from scallop hepatopancreas by microbial processes. (4/578)

A microbial process for removing cadmium from a homogenate of hepatopancreas, a waste of scallop processing, was devised to use this waste for value-added protein resources. Microorganisms were screened on the basis of the ability to remove cadmium from a medium with the initial concentration of 10 mg/l of cadmium. One soil isolate, identified as Xanthomonas sp. UR No. 2 by its taxonomical characteristics, removed 98% of the cadmium in the medium in 2 d. During cultivation of this strain in the homogenates of hepatopancreas digested by endopeptidases, 90% of cadmium was removed, while this strain had little effect on the simple non-digested homogenates. The mass balance of cadmium during homogenizations of the hepatopancreas tissues and cultivations in the protease-treated homogenate were examined. The content of crude proteins of culture supernatant treated by Xanthomonas sp. UR No. 2 was equivalent to those of various feedstuffs on the market.  (+info)

Correlation between genotype and beta-lactamases of clinical and environmental strains of Stenotrophomonas maltophilia. (5/578)

Heterogeneity of beta-lactamase production by 17 clinical and nine environmental isolates of Stenotrophomonas maltophilia was investigated using MICs of six different beta-lactam antibiotics, isoelectric focusing (IEF) and pulsed field gel electrophoresis. There was no clear correlation between the results of IEF, genotype and MIC determination. Environmental isolates were more susceptible than clinical isolates; eight clinical and none of the environmental isolates expressed high-level resistance to meropenem. Only two isolates expressed high-level resistance to ceftazidime. These results indicate that further studies are required to elucidate the extent of genetic heterogeneity within the L1 and L2 beta-lactamase genes.  (+info)

Community analysis of biofilters using fluorescence in situ hybridization including a new probe for the Xanthomonas branch of the class Proteobacteria. (6/578)

Domain-, class-, and subclass-specific rRNA-targeted probes were applied to investigate the microbial communities of three industrial and three laboratory-scale biofilters. The set of probes also included a new probe (named XAN818) specific for the Xanthomonas branch of the class Proteobacteria; this probe is described in this study. The members of the Xanthomonas branch do not hybridize with previously developed rRNA-targeted oligonucleotide probes for the alpha-, beta-, and gamma-Proteobacteria. Bacteria of the Xanthomonas branch accounted for up to 4.5% of total direct counts obtained with 4',6-diamidino-2-phenylindole. In biofilter samples, the relative abundance of these bacteria was similar to that of the gamma-Proteobacteria. Actinobacteria (gram-positive bacteria with a high G+C DNA content) and alpha-Proteobacteria were the most dominant groups. Detection rates obtained with probe EUB338 varied between about 40 and 70%. For samples with high contents of gram-positive bacteria, these percentages were substantially improved when the calculations were corrected for the reduced permeability of gram-positive bacteria when formaldehyde was used as a fixative. The set of applied bacterial class- and subclass-specific probes yielded, on average, 58.5% (+/- a standard deviation of 23.0%) of the corrected eubacterial detection rates, thus indicating the necessity of additional probes for studies of biofilter communities. The Xanthomonas-specific probe presented here may serve as an efficient tool for identifying potential phytopathogens. In situ hybridization proved to be a practical tool for microbiological studies of biofiltration systems.  (+info)

Peritonitis due to Stenotrophomonas maltophilia in patients undergoing chronic peritoneal dialysis. (7/578)

The occurrence of cases of Stenotrophomonas maltophilia peritonitis in chronic peritoneal dialysis (PD) patients prompted a review of our experience with this condition. A search of microbiology records revealed seven episodes of S. maltophilia peritonitis in 7 patients in 1996 - 3.8% of all PD patients - compared to no cases in 1994 and 1995 (p = 0.01). Patients ranged in age from 16 to 64 years; there were 3 males and 4 females. Six of seven episodes of peritonitis were community acquired and one was hospital acquired. No temporal clustering of cases was seen. Patients were from different urban and rural communities. Patients used the same commercially supplied dialysate fluid, different dialysis techniques, and were taught a no-touch technique for connection. Treatment of peritonitis required removal of the Tenckhoff catheter in 4 of 7 cases. Fingerprinting of six available isolates by polymerase chain reaction using primers derived from the conserved region of the 16/23Sr RNA gene sequence and pulsed field gel electrophoresis revealed all to be unique strains. A case-control study comparing 7 S. maltophilia cases to 21 PD controls showed case patients to be younger and more likely to be on immunosuppressive therapy. We conclude that S. maltophilia has emerged as an important cause of peritonitis in our continuous ambulatory PD population. Evidence to date suggests community acquisition with no evidence of a common source.  (+info)

Pseudoaneurysm of the subclavian artery due to Xanthomonas pneumonia in a patient with acute myeloid leukemia: its rupture treated by transcatheter coil embolization. (8/578)

A 52-year-old male with acute myeloid leukemia developed pseudoaneurysm of the subclavian artery. Pneumonia due to Xanthomonas maltophilia, which was multi-drug resistant, progressed to a lung abscess even under administration of antibiotics. This lung infection contiguous to the left carotid and subclavian arteries was suggested to have caused the pseudoaneurysm of the subclavian artery. The rupture of the aneurysm by penetration to the trachea amounted to about 1,000 ml of bleeding; fortunately the bleeding ceased spontaneously. Nonetheless, an emergency transcatheter coil embolization prevented re-bleeding. Endovascular treatment should be considered especially for aneurysms which develop in patients with underlying diseases.  (+info)

Sutami Street, Kentingan, Surakarta ABSTRACT Bacterial leaf blight (BLB) disease caused by bacteria Xanthomonas oryzae pv. oryzae (Xoo) commonly attacks rice crops and causes agricultural product loss. Phyllosphere bacteria in healthy plant tissue can inhibit the growth of pathogenic bacteria by producing bioactive compounds. This study aimed to isolate rice phyllosphere bacteria, test its inhibition activity to Xoo pathogen, and identify antagonist isolates that can be used as prospective biological control agent of BLB disease.Phyllosphere bacteria was isolated from rice leaves sample in healthy plants among HDB-infected plants in Sukoharjo,
Developing resistant cultivars requires an understanding of the dynamics of the pathogen populations as well as the genetics of host resistance. Bacterial leaf blight (BB), caused by the vascular pathogen Xanthomonas oryzae pv. oryzae, has become one of the most devastating diseases of rice. We demonstrate here the quantitative analyses of responses of near-isogenic lines carrying various BB resistance (R) genes and R-gene combinations against 16 X. oryzae pv. oryzae isolates representing Korean BB pathotypes. The estimated main effects of each R gene against the 16 isolates identified prominent differences in BB pathotypes between Korea and other countries. Three major aspects of our quantitative observations and statistical analysis are (i) strong and broad resistance of xa5; (ii) independent and additive genetic actions of Xa4, xa5, and Xa21 under digenic or trigenic status; and (iii) a strong quantitative complementation effect contributed by the functional alleles of Xa4 and Xa21. We ...
Previously, we successfully introduce the bacterial blight resistance trait from Oryza meyeriana into O. sativa using asymmetric somatic hybridization with O. meyeriana as the donor species. After years of breeding, a progeny named Y73 was generated with recurrent parent O. sativa L. ssp. japonica cv. Dalixiang, and it shows high resistance to broad-spectrum of bacterial blight pathogens Xanthomonas oryzae pv. Oryzae (Xoo). However, the resistance mechanism of Y73 is remain undiscovered. To provide insights into the high resistance phenotype of these plants, we examined the transcriptome response in leaves of Y73 to the bacterial blight infection in this study. Xoo inoculated and mock inoculated rice plants were grown in growth room and the global analysis of gene expression events in rice leaves at 24 hours post inoculation (hpi) were analyzed using Affymetrix Rice GeneChip microarrays. We used microarrays to detail the global programme of gene expression underlying Xoo infection in rice Y73. To find
The objective of this research was to identify bacterial spot-causing pathogen and bacterial antagonists for management of the disease using biocontrol agents as environmentally friendly alternatives. Isolates of Bacillus spp. were obtained from the soil samples collected at different localities in Serbia. Antibacterial activity of natural antagonists toward the pathogen isolated from infected pepper leaves was examined using a modified well-diffusion assay and standard germination test. Our results confirmed the presence of Xanthomonas euvesicatoria as the causal agent of bacterial spot of pepper. Screening of 32 Bacillus spp. isolates for antibacterial activity showed that 8 isolates inhibit growth of examined X. euvesicatoria isolates. Four isolates identified as Bacillus subtilis exhibited the highest antibacterial activity by in vitro test (from 5 to 14 mm inhibition zone of bacterial growth). The isolates positively influenced germination of pepper seeds, causing up to 16% and 70% increase ...

Bacterial blight (BB) of rice caused by Xanthomonas oryzae pv. oryzae (Xoo), remains a major production constraint in rice cultivation especially in irrigated and rainfed lowland ecosystems in India. The pathogen is highly dynamic in nature and knowledge on pathotype composition among the Xoo population is imperative for designing a scientific resistance breeding program. In this study, four hundred isolates of Xoo collected from diverse rice growing regions of India were analyzed for their virulence and genetic composition. Virulence profiling was carried out on a set of differentials consisting of 22 near isogenic lines (NILs) of IR24 possessing different BB resistance genes and their combinations along with the checks. It was observed that different NILs possessing single BB resistance gene were susceptible to about 59-94% of the Xoo isolates except IRBB 13 (containing BB resistance gene xa13), which showed susceptibility to about 35% of the isolates. Based on the reaction of the Xoo isolates on the
Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is the most devastating plant bacterial disease worldwide. Different bacterial blight resistance (R) genes confer race-specific resistance to different strains of Xoo. We fine mapped a fully recessive gene, xa24, for bacterial blight resistance to a 71-kb DNA fragment in the long arm of rice chromosome 2 using polymerase chain reaction-based molecular markers. The xa24 gene confers disease resistance at the seedling and adult stages. It mediates resistance to at least the Philippine Xoo races 4, 6 and 10 and Chinese Xoo strains Zhe173, JL691 and KS-1-21. Sequence analysis of the DNA fragment harboring the dominant (susceptible) allele of xa24 suggests that this gene should encode a novel protein that is not homologous to any known R proteins. These results will greatly facilitate the isolation and characterization of xa24. The markers will be convenient tools for marker-assisted selection of xa24 in breeding programs.

Treatment of rice tissues with purified preparations of a Xanthomonas oryzae pv. oryzae (Xoo) secreted plant cell wall degrading enzyme, Lipase/Esterase (LipA), elicits cell wall damage induced innate immune responses. LipA activity is required for induction of defense responses. In order to characterize the early events during elaboration of cell wall degrading enzyme, Lipase/Esterase (LipA) induced innate immune response in rice, we have performed global gene expression profiling of rice leaves treated with purified LipA at early time points, 30 minutes and 120min, after treatment. Whole genome transcriptional profiling was performed using Affymetrix Rice GeneChips

Bacterial small RNAs (sRNA) are small RNAs produced by bacteria; they are 50- to 500-nucleotide non-coding RNA molecules, highly structured and containing several stem-loops. Numerous sRNAs have been identified using both computational analysis and laboratory-based techniques such as Northern blotting, microarrays and RNA-Seq in a number of bacterial species including Escherichia coli, the model pathogen Salmonella, the nitrogen-fixing alphaproteobacterium Sinorhizobium meliloti, marine cyanobacteria, Francisella tularensis (the causative agent of tularaemia), Streptococcus pyogenes, the pathogen Staphylococcus aureus, and the plant pathogen Xanthomonas oryzae pathovar oryzae. Bacterial sRNAs effect how genes are expressed within bacterial cells via interaction with mRNA or protein, and thus can effect a variety of bacterial functions like metabolism, virulence, environmental stress response, and structure. In the 1960s, the abbreviation sRNA was used to refer to soluble RNA, which is now ...
The Xanthomonas citri pv. citri (X. citri) is a phytopathogenic bacterium that infects different species of citrus plants where it causes canker disease. The adaptation to different habitats is related to the ability of the cells to metabolize and to assimilate diverse compounds, including sulfur, an essential element for all organisms. In Escherichia coli, the necessary sulfur can be obtained by a set of proteins whose genes belong to the cys regulon. Although the cys regulon proteins and their importance have been described in many other bacteria, there are no data related to these proteins in X. citri or in the Xanthomonas genus. The study of the relevance of these systems in these phytopathogenic bacteria that have distinct mechanisms of infection is one essential step toward understanding their physiology. In this work, we used bioinformatics, molecular modeling and transcription analysis (RT-PCR) to identify and characterize the putative cys regulon genes in X. citri. We

Bacterial leaf blight (BLB) is one of the most devastating diseases on rice, causing annual yield losses up to 60% [1]. The causal agent, Xanthomonas oryzae pv. oryzae (Xoo) is a rod-shaped, obligately aerobic, gram-negative bacterium that is motile by means of a single polar flagellum. Like many other Xanthomonas species, Xoo produces a wide variety of virulence factors to protect itself and inflict disease. These factors include extracellular polysaccharides (EPS), lipopolysaccharides, adhesins, cell wall degrading enzymes, and type III effectors [2,3]. Most of these traits are under tight control of quorum sensing (QS) regulatory systems.. QS is a cell-to-cell communication system by which bacteria track changes in cell density and adjust gene expression accordingly. Central to QS is the production, detection, and response to extracellular signal molecules called autoinducers (AIs). At low cell density, bacteria produce basal levels of AIs, which subsequently diffuse away in the environment, ...

The rice transcription factor WRKY45 plays a crucial role in salicylic acid (SA)/benzothiadiazole (BTH)-induced disease resistance. Its knockdown severely reduces BTH-induced resistance to the fungal pathogen Magnaporthe oryzae and the bacterial pathogen Xanthomonas oryzae pv. oryzae (Xoo). Conversely, overexpression of WRKY45 induces extremely strong resistance to both of these pathogens. To elucidate the molecular basis of WRKY45-dependent disease resistance, we analyzed WRKY45-regulated gene expression using rice transformants and a transient gene expression system. We conducted a microarray analysis using WRKY45-knockdown (WRKY45-kd) rice plants, and identified WRKY45-dependent genes among the BTH-responsive genes. The BTH-responsiveness of 260 genes was dependent on WRKY45. Among these, 220 genes (85%), many of which encoded PR proteins and proteins associated with secondary metabolism, were upregulated by BTH. Only a small portion of these genes overlapped with those regulated by OsNPR1/NH1,
Bacterial leaf streak (BLS), also known as black chaff, is a common bacterial disease of wheat. The disease is caused by the bacterial species Xanthomonas translucens pv. undulosa. The pathogen is found globally, but is a primary problem in the US in the lower mid-south and can reduce yields by up to 40 percent.[6] BLS is primarily seed-borne (the disease is transmitted by seed) and survives in and on the seed, but may also survive in crop residue in the soil in the off-season. During the growing season, the bacteria may transfer from plant to plant by contact, but it is primarily spread by rain, wind and insect contact. The bacteria thrives in moist environments, and produces a cream to yellow bacterial ooze, which, when dry, appears light colored and scale-like, resulting in a streak on the leaves. The invasion of the head of wheat causes bands of necrotic tissue on the awns, which is called Black Chaff.[14] The disease is not easily managed, as there are no pesticides on the market for ...

Multilocus sequence analysis (MLSA) and type III effector (T3E) repertoire mining were performed to gain new insights into the genetic relatedness of Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc), two major bacterial pathogens of rice. Based on a collection of 45 African and Asian strains, we first sequenced and analysed three housekeeping genes by MLSA, Bayesian clustering and a median-joining network approach. Second, we investigated the distribution of 32 T3E genes, which are known to be major virulence factors of plant pathogenic bacteria, in all selected strains, by polymerase chain reaction and dot-blot hybridization methods. The diversity observed within housekeeping genes, as well as within T3E repertoires, clearly showed that both pathogens belong to closely related, but distinct, phylogenetic groups. Interestingly, these evolutionary groups are differentiated according to the geographical origin of the strains, suggesting that populations of Xoo and Xoc might

Xanthomonas oryzae pv. oryzae (Xoo) is widely prevalent and causes Bacterial Leaf Blight (BLB) in Basmati rice grown in different areas of Pakistan. There is a need to use environmentally safe approaches to overcome the loss of grain yield in rice due to this disease. The present study aimed to develop inocula, based on native antagonistic bacteria for biocontrol of BLB and to increase the yield of Super Basmati rice variety. Out of 512 bacteria isolated from the rice rhizosphere and screened for plant growth promoting determinants, the isolate BRp3 was found to be the best as it solubilized 97 μg/ mL phosphorus, produced 30 μg/mL phytohormone indole acetic acid and 15 mg/ L siderophores in vitro ...
Bacterial blight (BB) of rice caused by Xanthomonas oryzae pv oryzae (Xoo) is one of the major constraints to productivity in South-East Asia. The strategy of using major genes, singly or in combination, continues to be the most effective approach for BB management. Currently, more than two dozen genes have been designated but not all the known genes are effective against all the prevalent pathotypes. The challenge, therefore, is to continue to expand the gene pool of effective and potentially durable resistance genes. Wild species constitute an important reservoir of the resistance genes including BB. An accession of Oryza nivara (IRGC 81825) was found to be resistant to all the seven Xoo pathotypes prevalent in northern states of India. Inheritance and mapping of resistance in O. nivara was studied by using F2, BC2F2, BC3F1 and BC3F2 progenies of the cross involving Oryza sativa cv PR114 and the O. nivara acc. 81825 using the most virulent Xoo pathotype. Genetic analysis of the segregating ...

Stable adhesion to an appropriate surface is the first step in biofilm formation [33]. The ability of X. citri to form biofilms enhances the epiphytic persistence of this species on host leaves, which plays an important role in the early stages of infection [18, 21]. The present study indicates that a putative DEAH-box ATP-dependent RNA helicase, HrpB, may perform many roles in X. citri because it is important for adherence to surfaces and motility and for the epiphytic survival of the bacteria on citrus leaves, which results in a reduction in the development of symptoms. The phenotype changes observed in ∆hrpB may be caused by the positive regulation of T4P genes, such as fimA (XAC3241), by the HrpB protein in wild-type X. citri. Our results show that the predicted HrpB protein in X. citri exhibits several characteristics that are considered typical for RNA helicases [2, 4]. These include a DEAH-like helicase superfamily domain and the presence of an ATP-binding region (GAGKT) (Fig. 1). ...

Comparative analysis of Xcaw12879 and XccA306 identified multiple strain-specific genes that might contribute to the differences in virulence and host range. Among the genes present in Xcaw12879, but absent in XccA306, two effector genes xopAG (avrGf1) and xopAF were identified in Xcaw, XauB and XauC but were not present in XccA306 genome (Table 1). The presence of these effectors in limited host range strains causing citrus canker and not in the broader host range XccA306 makes them prime candidates for effectors that could affect host specificity. Importantly, the role of xopAG (avrGf1) in limiting the host range of Xcaw has been confirmed previously [7]. The xopAG gene belongs to the avrGf1 family and has been shown to trigger HR in grapefruit [7]. AvrGf1 in Xcaw shows only about 45% identity to its homolog XAUC_04910 in XauC whereas the homolog XAUB_03570 in XauB is interrupted by a transposon and might be non-functional, which probably contributes to the broader host range of XauB compared ...
Rice is the number one staple food for the worlds poorest and undernourished people. More than half of the worlds population eats rice every day. In sub-Saharan Africa, rice is the fastest growing food source that provides more food calories than any other crop. One dangerous threat to food security, is the rice disease bacterial blight, caused by the bacterium Xanthomonas oryzae pv. oryzae (Xoo). The annual losses caused by bacterial blight are estimated at 3.6 billion US dollars in India alone. Xoo can destroy a smallholders entire annual harvest, putting their food supply, income and land ownership at risk.. Healthy Crops aims to provide these farmers with effective tools to combat bacterial blight and thus eliminate the epidemic in the long term. The consortium is comprised of six research institutions on three continents, including two universities in the USA (U. of Florida and U. Missouri), the International Centre for Tropical Agriculture (CIAT) in Columbia, the Institut de Recherche ...
The rice XA21 receptor kinase confers robust resistance to the bacterial pathogen Xanthomonas oryzaepv. oryzae (Xoo). We developed a detached leaf infection assay to quickly and reliably measure activation of the XA21-mediated immune response using genetic markers. We used RNA sequencing of elf18 treated EFR:XA21:GFP plants to identify candidate genes that could serve as markers for XA21 activation. From this analysis, we identified eight genes that are up-regulated in both in elf18 treated EFR:XA21:GFP rice leaves and Xoo infected XA21 rice leaves. These results provide a rapid and reliable method to assess bacterial-rice interactions.

Following publication of our article [1], we found errors in analyses performed by the corresponding author (DJS) related to the phylogenetic relationship between Xylella species and the other xanthomonads. These errors do not make any difference to the main findings and conclusions reported in our paper. For example, the phylogenetic positions of NCPPB1131, NCPPB1132 and NCPPB4393 within the Group 1 Xanthomonas species are unaffected. However, we wish to apologize to the authors of a previous work [2] for creating any negative impression on the quality of their phylogenetic analyses and to take this opportunity to rectify the errors.

Bacterial leaf blight (BLB), caused by X. oryzae pv. oryzae (Xoo), is one of the most destructive diseases of rice due to its high epidemic potential. Understanding BLB resistance at a genetic level is important to further improve the rice breeding that provides one of the best approaches to control BLB disease. In the present investigation, a collection of 96 accessions was used in the genome‐wide association study (GWAS) for BLB resistance loci against four Korean races of Xoo that were represented by the prevailing BLB isolates under Xoo differential system. The results of the bioassay using a selected set of 96 accessions showed that a large number of accessions (93.75%) were resistant to K1 race, while the least number of accessions (34.37%) resisted K3a race. For races K2 and K3, the resistant germplasm proportion remained between 66.67 to 70.83%. The genotypic data produced SNP matrix for a total of 293,379 SNPs. After imputation the missing data was removed, which exhibited 34,724 SNPs for
Xanthomonas oryzae pv. oryzae (Xoo) is a gram-negative pathogen which causes leaf blight disease. Known traditional bactericides are not much more effective in inhibiting this bacteria than before. Selecting the virulence factor of the bacteria as the target without affecting their growth has been considered as a novel method for developing new anti-microbial drugs. Type III secretion systems (T3SS) are one of the important and highly conserved virulence factors in most gram-negative pathogens, which has been considered as an effective target to develop new anti-microbial drugs. In order to discover potential anti-microbial drugs against Xoo pathogens, a series of ethyl 2-nitro-3-arylacrylates compounds were screened. Among them, the compounds I-9, I-12, and I-13 could highly inhibit the promoter activity of a harpin gene hpa1, which were used to further check for the influence on bacterial growth and on the hypersensitive response (HR) caused by Xoo bacteria on non-host plants. The results showed that
Bacterial blight, caused by Xanthomonas oryzae pv. oryzae (Xoo), is one of the most devastating diseases resulting in a huge loss of the total rice productivity. The initial interaction between rice and Xoo takes place in the host apoplast and is mediated primarily by secretion of various proteins from both partners. Yet, such secretory proteins remain to be largely identified and characterized. T ...
A more complete study of ionic concentrations and fluxes in the giant internodal cells of Nitella translucens has been made. The vacuolar concentrations were 76 mM K and 170 mM Cl. The content of the chloroplast layer was 135 mµmoles K/cm2 and 215 mµmoles Cl/cm2; in a layer 9 µ thick these correspond to concentrations of 150 mM K and 240 mM Cl. Such a high level of chloride requires active transport of chloride into the cytoplasm, either at the plasmalemma or at the membranes bounding the cytoplasmic particles; it cannot be achieved by active transport of chloride only at the tonoplast. With concentrations of 0.1 mM K and 1.3 mM Cl outside, the fluxes into the cytoplasm had mean values of 1.0 to 1.4 µµmoles K/cm2sec. and 2.1 to 2.8 µµmoles Cl/cm2sec.; the corresponding fluxes from the cytoplasm to the vacuole were about 110 µµmoles K/cm2sec. and 175 µµmoles Clcm2sec. The transfer of both potassium and chloride to the vacuole under different conditions appeared to be correlated with ...

Xanthomonas axonopodis pv manihotis (Xam) is the causal agent of cassava bacterial blight (CBB)worldwide. To develop a well-organized disease management policy in a country, the diversity of pathogenspopulation must be known. The bacterial populations of Xanthomonas axonopodispvmanihotis (Xam)obtained as flora cassava leaves and stems, in Nigeria were characterized by their biochemical and thephysiological reactions with basic routine microbiological techniques which were subjected to cluster analysis.A total of 75 bacteria strains were studied, made up of sixty eight (68) Xanthomonas axonopodis pv manihotis(Xam), four (4)Xanthomonas axonopodispv cassavae (Xac) and three (3) unidentified species. The isolateswere similar to one another in most of the cultural and physiological characteristics. They were all able tohydrolyze aesculin and showed a positive reaction to catalase, citrate and oxidase tests. They were indole,methyl-red, Voges-Proskauer and urease negative. The analysis carried out on ...
We report here on the isolation and characterization of a new member of the Xanthomonas avrBs3/pthA gene family, hssB3.0, from X. axonopodis pv. citri that confers host-specific suppression of virulence and might control the bacterial elicitation of resistance in C. grandis. hssB3.0 reduces the ability of X. axonopodis pv. citri to multiply in the Citrus species, enhances the accumulation of PAL gene transcripts, and, consequently, reduces lesion expansion. The 3.0-kb BamHI fragment of hssB3.0 has not been found in normally aggressive Xanthomonas strains but has been found in all less aggressive strains investigated thus far. Our findings also indicate that pthA-KC21 functions as a pathogenicity gene. hssB3.0 induces a defense response on the host; however, this gene partially interrupts canker symptom development elicited by pthA-KC21. Usually, avirulence genes are associated with the onset of the HR by the host plant, and thus, the infection is stopped, and there is not a further development ...

INTRODUCTION. Leaf scald is a disease that affects sugarcane crops (Saccharum officinarum L.) The pathology is caused by the Gram-negative bacterium Xanthomonas albilineans, which causes the occlusion of xylem vessels and prevents the differentiation of chloroplasts (Huerta Lara et al., 2009). This disease has three states. In the latent phase, no symptoms are evident. The chronic phase appears at 3-mo of age and disappears after approximately 3-mo. The chronic phase is characterized by stem necrosis and the presence of white lines parallel to the leaf midrib. The acute phase is characterized by the immediate death of the seedling (Rott et al., 1995). Leaf scald is one of the most serious and devastating disease affecting sugarcane crops worldwide (Fontaniella et al., 2007). This disease has been detected in 57 countries and, in its acute phase, decreases the juice yield and quality in the sugar industry; in fact, losses exceeding 90% have been reported (Swings and Civerolo, 1993; Destefano et ...
Xanthomonas axonopodis pv. citri (Xac) is the causative agent of citrus canker. This bacterium develops a characteristic biofilm on both biotic and abiotic surfaces. To evaluate the participation of the single flagellum of Xac in biofilm formation, mutants in the fliC (flagellin) and the flgE (hook) genes were generated. Swimming motility, assessed on 0.25 % agar plates, was markedly reduced in fliC and flgE mutants. However, the fliC and flgE mutants exhibited a flagellar-independent surface translocation on 0.5 % agar plates. Mutation of either the rpfF or the rpfC gene, which both encode proteins involved in cell-cell signalling mediated by diffusible signal factor (DSF), led to a reduction in both flagellar-dependent and flagellar-independent surface translocation, indicating a regulatory role for DSF in both types of motility. 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

1. Regulation of Resistance to copper in Xanthomonas axonopodis pv. Vesicatoria. (9) In this research, the scientist at the University of California, Riverside, attempt to identified the plasmid-borne copper resistance genes of X. axonopodis. Copper is required for eukaryotic and prokaryotic cells to maintain cell growth. However, having too much copper can be harmful to cells because it has the ability to generate free radicals which are able to damage DNA and lipid membranes. This is the reason why farmers spray copper on their plants in order to limit the bacteria population preying on plants. Unfortunately, as with all excessive use of chemicals on microorganisms, there are drawbacks that the bacteria would develop a detoxification system to protect themselves. As such, there are strains of X. axonopodis able to develop a copper resistance in their plasmid (9). The copABCD operon of X. axonopodis is specifically induced by copper. Thereby, expression of resistance to toxic levels of copper ...
readily recovered on selective media, the DNA probe assay is more rapid and specific. Furthermore, the DNA probe is feasible for assaying large numbers of samples in a relatively short time.. Serological tests have been used for rapid identification and detection of X. campestris pv. campestris. However, polyclonal antibodies against strains of X. campestris pv. campestris often cross-react with one or a few other pathovars of X. campestris (Alvarez and Lou, 1985; Franken et a1., 1992; Schaad, 1978; Thaveechai and Schaad, 1984, 1986). For example, strains of X. campestris pv. vesicatoria often react with the polyclonal antibodies of X. campestris pv. campestris (Alvarez and Lou, 1985; Franken et al., 1992; Schaad, 1978; Thaveechai and Schaad, 1984, 1986). Xanthomonas campestris pv. vesicatoria is a widely distributed pathogen causing bacterial spot disease on tomato and pepper in Taiwan (Hartman et al., 1990). The chance of introducing this bacterial spot pathogen to the fields of cruciferous ...
The Xanthomonadaceae are a family of Gram negative bacteria belonging to the order Xanthomonadales in the gammaproteobacteria. They are typically characterized as environmental organisms and are found in soil and water, as well as plant tissues. Many Xanthomonadaceae, especially species from the genera Xanthomonas and Xylella, cause plant diseases. Only one, Stenotrophomonas maltophilia, has isolates known to be opportunistic human pathogens.Xanthomonas campestris pv. campestris causes black rot, which affects crucifers such as Brassica and Arabidopsis. Symptoms include marginal leaf chlorosis and darkening of vascular tissue, accompanied by extensive wilting and necrosis. This bacterium is grown commercially to produce the exopolysaccharide xanthan gum, which is used to control viscosity and as a stabilizing agent in many industries. (HAMAP: XANCP ...

Xanthomonas campestris pv. campestris (Xcc) is the phytopathogen that causes black rot in crucifers. The xanthan polysaccharide and extracellular enzymes produced by this organism are virulence factors, the expression of which is upregulated by Clp (CRP-like protein) and DSF (diffusible signal factor), which is synthesized by RpfF. It is also known that biofilm formation/dispersal, regulated by the effect of controlled synthesis of DSF on cell-cell signalling, is required for virulence. Furthermore, a deficiency in DSF causes cell aggregation with concomitant production of a gum-like substance that can be dispersed by addition of DSF or digested by exogenous endo-β-1,4-mannanase expressed by Xcc. In this study, Western blotting of proteins from a mopB mutant (XcMopB) showed Xcc MopB to be the major outer-membrane protein (OMP); Xcc MopB shared over 97 % identity with homologues from other members of Xanthomonas. Similarly to the rpfF mutant, XcMopB formed aggregates with simultaneous production of a
Bacterial plant pathogens belonging to the Xanthomonas genus are adapted to their host plants and are not known to colonize other environments. Xanthomonas colonize host parts such as leaves, stems and roots before entering vascular tissues and engaging in an invasive pathogenic phase. These bacterial strains have evolved strategies to adapt to life in this environment. The host-pathogen interactions of Xanthomonas vasicola (Xv) need to be well understood to properly map the target genes in the host and pathogen so as to understand the mechanism of resistance. Genotypic characterization, based on the analysis of restriction fragment length polymorphism of virulence factor fragment products was performed on members of the X. vasicola pv. musacearum (Xcm) and X. vasicola pv. vasculorum (Xvv) from varying geographical locations. The study showed that Xcm and Xvv are different from each other based on amplification of virulence factors within fragments of their DNA. Bacterial strains of similar species

The Gram-negative phytopathogenic bacterium Xanthomonas campestris pv. campestris recruits the hrp/T3SS system to inject pathogenicity effector proteins into host cells and uses the rpf/DSF cell-cell signaling system to regulate the expression of virulence factors such as extracellular enzymes and polysaccharide. Whether these two systems have any connection is unknown. Positive regulator candidates affecting hrpX expression were identified by sacB strategy. The transcriptional expression was determined by qRT-PCR and GUS activity analysis. Transcriptome analysis was performed by RNA deep-sequencing. The hypersensitive response (HR) was determined in the nonhost plant pepper ECW-10R and electrolyte leakage assay. Mutation of the gene encoding the sensor RpfC of the rpf/DSF system significantly reduced the expression of hrpX, the key regulator of the hrp/T3SS system, all of the genes in the hrp cluster and most reported type III effector genes. Mutation of rpfG did not affect the expression of hrpX. The

TonB-dependent receptors (TBDRs) are outer membrane proteins mainly known for the active transport of iron siderophore complexes in Gram-negative bacteria. Analysis of the genome of the phytopathogenic bacterium Xanthomonas campestris pv. campestris (Xcc), predicts 72 TBDRs. Such an overrepresentation is common in Xanthomonas species but is limited to only a small number of bacteria. Here, we show that one Xcc TBDR transports sucrose with a very high affinity, suggesting that it might be a sucrose scavenger. This TBDR acts with an inner membrane transporter, an amylosucrase and a regulator to utilize sucrose, thus defining a new type of carbohydrate utilization locus, named CUT locus, involving a TBDR for the transport of substrate across the outer membrane. This sucrose CUT locus is required for full pathogenicity on Arabidopsis, showing its importance for the adaptation to host plants. A systematic analysis of Xcc TBDR genes and a genome context survey suggested that several Xcc TBDRs belong to other
Xanthomonas campestris was used for producing xanthan gum using date syrup, prepared from low quality dates, as a substrate. Fermentation was carried out with date syrup and sucrose syrup at 28 ˚C and pH 6.8 in a rotary benmarin shaker (240 rpm). The effect of fermentation period (24, 48, 72, 96 and 120 h) on xanthan gum production was studied. The results showed that EPS concentration increased with an increase in fermentation time with a maximum yield of 0.89 g/100 mL after 96 h which was much higher than that of the sucrose-containing medium (0.18 g/100 mL). The effect of pH on the yield of the purified xanthan was also examined. The optimum pH for xanthan production was determined to be 5.5. The xanthan obtained through this study was compared to commercial xanthan, and showed a very similar chemical composition confirmed by thin layer chromatography (TLC) and Fourier transform infrared spectroscopy (FT IR). The results revealed that date syrup has a potential to be used as a suitable substrate

Amino acids are required as building blocks for proteins, the essential molecular machines and structures of living cells. We have identified the metabolic pathways, enzymes and genes by which Xanthomonas campestris synthesizes all amino acids required to build proteins. For 19 of the 20 amino acids their biosynthetic routes had not been described before. To determine the metabolic pathways we combined careful genome analysis with complex experimental NMR analysis.

To date, two types of enzymes that are responsible for primary attack of polyisoprene in rubber-degrading microorganisms have been identified [1]. One is the latex clearing protein (Lcp), first isolated from Streptomyces sp., which does not have any metal ions or cofactors [2]. The other is the rubber oxygenase RoxA of Xanthomonas sp., a dihaem c-type cytochrome that cleaves cis-1,4-polyisoprene, the main constituent of natural rubber, to 12-oxo-4,8-dimethyltrideca-4,8-diene-1-al [3, 4]. The crystal structure of RoxA, solved at 1.8 Å resolution, was released today [5]. ...
Xanthomonas axonopodis pv. citri (Xac) o causador do cancro de plantas c tricas. Entre os potenciais fatores de virul ncia codificados por Xac, est o Sistema de Secre o do Tipo IV (T4SS), um grande complexo multiprot ico que atravessa o periplasma e as membranas interna e externa de bact rias Gram-negativas. O T4SS est envolvido com secre o de prote nas e/ou DNA para o meio extracelular ou diretamente no interior da c lula do hospedeiro. Este Sistema requer tipicamente 12 prote nas para realizar suas fun es: VirB1-VirB11 e VirD4. O T4SS codificado pelo cromossomo de Xac est aparentemente incompleto, devido a n o codificar nenhuma prote na com similaridade de seq ncia a VirB7. Os objetivos deste trabalho s o estudar a estrutura, fun o e intera es das prote nas do T4SS de Xanthomonas.

DROPSA is a 4-year project involving 26 partners from Europe, Asia, New Zealand and North America. It will focus on new and emerging threats due to Drosophila suzukii, and the bacterial pathogens:. Pseudomonas syringae pv. actinidiae (Psa), Xanthomonas fragariae (Xf), and X. arboricola pv. pruni (Xap). These pathogens and Drosophila suzukii are a major concern and challenge to the fruit industry because their eradication or containment is not possible. Hence the development of targeted integrated pest management (IPM) is vital to maximize the economic impact on fruit production in the EU region.. High lights of the DROPSA-project will be presented at the ISFC 2018 conference.. ...

2003-12-01 Resumo em português Apesar de amplamente empregados em lavouras de tomate para processamento industrial no Brasil, fungicidas cúpricos e antibióticos registrados para uso agrícola nem sempre resultam em controle eficiente das bacterioses que afetam a cultura. O aparecimento de estirpes resistentes é uma das causas dessa baixa eficiência. Avaliou-se, in vitro, a sensibilidade a cobre, estreptomicina e oxitetraciclina de 389 isolados de Xanthomonas spp. associadas à mancha-bacteriana do (mais) tomateiro, sendo 92 de X. axonopodis pv. vesicatoria (60 do grupo A/raça T1 e 32 do C/raça T3), 93 de X. vesicatoria (grupo B/raça T2) e 204 de X. gardneri (grupo D/raça T2). Os isolados foram obtidos de plantas doentes em campos comerciais de tomate para processamento industrial nos estados de Goiás, Minas Gerais, Pernambuco e Bahia, nos anos de 1995 a 1998 e em 2000. Alíquotas de 5 ml de suspensões bacterianas foram depositadas em meio Nutriente-Ágar suplementado com ...

Xanthan gum derives its name from the strain of bacteria used during the fermentation process. This bacteria is known as Xanthomonas campestris and is the same bacteria responsible for causing black rot to form on broccoli and cauliflower. These bacteria form a slimy substance which acts as a natural stabilizer or thickener. When Xanthomonas campestris is combined with corn sugar, the result is a colorless slime called xanthan gum.
