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 ...

The export of cashew (Anacardium occidentale) nuts generates millions of dollars for the Brazilian economy annually. However, production may be limited by the occurrence of diseases that affect cashew trees, such as Xanthomonas spot and angular leaf spot, which are caused by pigmented strains of Xanthomonas and Xanthomonas citri pv. anacardii, respectively. Thirty-one pigmented strains of Xanthomonas were characterized for phenotypic, pathogenic, and molecular attributes. These strains were similar to X. citri pv. anacardii in phenotypical characteristics, sensitivity to antibiotics and copper compounds used in agriculture, epidemiology, and repetitive sequence-based polymerase chain reaction (rep-PCR) profiles. When inoculated into Brazilian pepper, cashew, mango, and hog plum seedlings, the pigmented strains of Xanthomonas and X. citri pv. anacardii produced similar symptoms. However, the pigmented strains of Xanthomonas were more aggressive toward cashew plants than toward the other hosts ...

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 Xanthomonadales are a bacterial order within the Gammaproteobacteria. They are one of the largest groups of bacterial phytopathogens, harbouring species such as Xanthomonas citri, Xanthomonas euvesicatoria, Xanthomonas oryzae and Xylella fastidiosa. These bacteria affect agriculturally important plants including tomatoes, bananas, citrus plants, rice, and coffee. Many species within the order are also human pathogens. Species within the Stenotrophomonas genus are multidrug resistant opportunistic pathogens that are responsible for nosocomial infections in immunodeficient patients. The Xanthomonadales are gram-negative, catalase positive, non-spore forming obligate aerobes. Members belonging to the order are straight rods lacking prosthecae. While some members are non-motile, other species within the order are motile by means of flagella. Stenotrophomonas is the only genus capable of nitrate reduction within the Xanthomonadales. The Xanthomonadales consist of 28 validly named genera among two ...

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

A gene cluster for xanthomonadin production was obtained from Xanthomonas campestris pv. campestris, the causal agent of black rot of crucifers. Eighteen mutants affected in pigment production were identified. Seventeen of these mutants were fully pathogenic, and they could be divided into four classes based on the absorption spectra of pigment extracts. Sequences from a 25.4-kbp genomic clone (pIG102) restored pigment production to all 18 mutants and to a naturally occurring nonpigmented strain of X. c. pv. mangiferaeindicae. Analysis of pIG102 by subcloning and mutant restoration identified six functional domains for pigment production, and this genomic region conferred the production of a xanthomonadin pigment to Pseudomonas fluorescens. Clone pIG102 and subcloned derivatives encoding various functional domains were used as DNA probes in colony blot hybridizations with genomic DNA of 105 strains of Xanthomonas, Pseudomonas, Erwinia, and Clavibacter. Clone pIG102 hybridized strongly to all ...

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

Very succinctly plant-bacteria interactions can be thought as governed at molecular level mainly by three types of proteins: plant PRRs (pathogen recognition receptors), bacterial effectors and plant resistance proteins. PRRs are proteins recognizing highly conserved structures and molecules in microorganisms named MAMP (microbial-associated molecular patterns) and mediate MAMP-triggered immunity (MTI), which is efficient against non-adapted pathogens. Pathogens have developed effector proteins to suppress MTI. In turn, plants can counteract the action of effector by the specific recognition of effectors mediated by resistance proteins which will trigger a strong defence response known as ETI (effector-triggered immunity) [1].. During the past decade, small RNAs have also been found to be key players in mediating plant-pathogen interactions as well as many other biological processes. microRNAs (miRNAs) are important regulators of eukaryotic gene expression. They are transcribed from nuclear ...

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]. ...

Nonhomologous end joining (NHEJ) eliminates DNA double-strand breaks (DSBs) by direct ligation. NHEJ involves binding of the KU heterodimer to double-stranded DNA ends, recruitment of DNA-PKcs (MRX complex in yeast), processing of ends, and recruitment of the DNA ligase IV (LIG4)-XRCC4 complex, which brings about ligation. A recent study shows that bacteria accomplish NHEJ using just two proteins (Ku and DNA ligase), whereas eukaryotes require many factors. NHEJ repairs DSBs at all stages of the cell cycle, bringing about the ligation of two DNA DSBs without the need for sequence homology, and so is error-prone ...

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.

We identified the determinants for copper resistance on a 7,652-bp XbaI/EcoRI chromosomal fragment in X. campestris pv. vesicatoria strain XvP26 from Taiwan. Although metal resistance is commonly associated with plasmids in bacteria (39), gene clusters associated with the chromosome that result in copper resistance have been identified in phytopathogenic Pseudomonas and Xanthomonas spp. (26, 27). Previously, copper resistance in X. campestris pv. vesicatoria was associated only with plasmids (9, 23, 41). The size of the 5.5-kb region that is functional in copper resistance in XvP26 is similar to the sizes of P syringae pv. tomato (8), X. arboricola pv. juglandis (26), and X. campestris pv. vesicatoria (46) regions, which are 4.5, 4.9, and 6.0 kb long, respectively.. As a result of sequencing of the 7.6-kb fragment, five ORFs were identified in the cluster of genes associated with copper resistance. Three of these five ORFs were required for a high level of resistance in transconjugant screening. ...

Description: Plasmid-borne copper resistance genes from copper-resistant strains of Xanthomonas campestris pv. vesicatoria from California, Florida, and Oklahoma shared structural similarities. A strain of X. campestris pv. campestris also contained plasmid-borne copper resistance genes similar to the resistance genes from X. campestris pv. vesicatoria. Furthermore, a region of the copper resistance genes from X. campestris pv. vesicatoria 07882 hybridized with copA, the first gene of the copper resistance operon (cop) of Pseudononas syringae pv. tomato. A copper-inducible protein of similar size to CopA was detected by Western blot (immunoblot) analysis from the wild-type strain 07882 and from the cloned copper resistance genes of 07882 introduced into a copper-sensitive strain of X. campestris pv. vesicatoria. A low level of hybridization was observed with chromosomal DNA from other xanthomonads when the copper resistance genes from strain 07882 were used as probes. ...

Cowpea bacterial blight (CoBB), caused by Xanthomonas axonopodis pv. vignicola (Xav), is a worldwide major disease of cowpea [Vigna unguiculata (L.) Walp.]. Among different strategies to control the disease including cultural practices, intercropping, application of chemicals, and sowing pathogen-free seeds, planting of cowpea genotypes with resistance to the pathogen would be the most attractive option to the resource poor cowpea farmers in sub-Saharan Africa. Breeding resistance cultivars would be facilitated by marker-assisted selection (MAS). In order to identify loci with effects on resistance to this pathogen and map QTLs controlling resistance to CoBB, eleven cowpea genotypes were screened for resistance to bacterial blight using 2 virulent Xav18 and Xav19 strains isolated from Kano (Nigeria). Two cowpea genotypes Danila and Tvu7778 were identified to contrast in their responses to foliar disease expression following leaf infection with pathogen. A set of recombinant inbred lines (RILs) ...

This study was carried out to investigate the potential role of banana weevils as vectors of Xanthomonas campestris pv. musacearum (Xcm), causal agent of banana wilt. Weevils captured from Xcm-infected plants were tested for presence of Xcm, and further raised on Xcm-infected corms for later use as vectors to transmit the pathogen to healthy tissue-cultured plantlets. Analysis of weevils captured from diseased fields revealed more weevils contained Xcm originating from Mbwazirume compared with Kayinja cultivars. Colonies of Xcm were recovered from the weevil external body surface, internal organs (mouth parts and abdomen) and faecal matter. There was significantly higher Xcm presence and cfu mL−1 on the external weevil body surface than within the internal organs. Bacterial populations declined progressively from the external body surface, internal mouth parts, internal abdominal parts and the faecal matter. Following placement of weevils previously fed on Xcm-exuding corms in close ...

The resistance of microorganisms to conventional antibiotics has prompted researchers to produce new antimicrobial compounds. Antimicrobial peptides can be alternatives to chemical antibiotics. Antimicrobial peptides are produced approximately by all living organisms to fight infection. Lactoferrin is an iron glycoprotein that plays an important role in the immune system. Lactoferricin and lactoferrampine have stronger antimicrobial activities than lactoferrin. In this study, we investigated the inhibitory effects of a combination of chimeric bovine lactoferricin and lactoferrampine on microorganisms including Escherichia coli, Staphylococcus aureus, Salmonella typhimurium, Enterococcus faecalis, and Listeria monocytogenes, as well as plant pathogens including Pseudomonas syringae pv. syringae, Pseudomonas viridiflava, Xanthomonas translucens, Xanthomonas perforans, Erwinia amylovora, Pectobacterium carotovorum, and Agrobacterium tumefaciens. The results showed that chimeric bovine lactoferrin had a

Molecular typing of pathogen populations is an important tool for the development of effective strategies for disease control. Diverse molecular markers have been used to characterize populations of Xanthomonas axonopodis pv. manihotis (Xam), the main bacterial pathogen of cassava. Recently, diversity and population dynamics of Xam in the Colombian Caribbean coast were estimated using AFLPs, where populations were found to be dynamic, diverse and with haplotypes unstable across time. Aiming to examine the current state of pathogen populations located in the Colombian Eastern Plains, we also used AFLP markers and we evaluated the usefulness of Variable Number Tandem Repeats (VNTRs) as new molecular markers for the study of Xam populations. The population analyses showed that AFLP and VNTR provide a detailed and congruent description of Xam populations from the Colombian Eastern Plains. These two typing strategies clearly separated strains from the Colombian Eastern Plains into distinct populations

Plant height and bacterial spot severity. Shoot pruning did not affect tomato plant height at 3 and 6 WAT, regardless of cultivars and bacterial spot inoculation (data not shown). Bacterial spot inoculation increased disease severity based on an AUDPC of 1445 (an average disease severity of 41%) in inoculated plots versus an AUDPC of 821 (an average disease severity of 29%) in noninoculated plots averaged across both seasons (data not shown). Disease severity was greater at the end of the spring trial than at the end of the fall 2009 trial (65% and 35%, respectively). Inversely, initial disease severity was much greater in the fall study (24% disease severity in noninoculated plots) than the spring trial (1.5% disease severity in noninoculated plots). Tygress was more susceptible to bacterial spot than Security-28, exhibiting 20.4% more disease on average.. Early tomato fruit weight. Early extra-large fruit weight was affected by tomato cultivars and the inoculation of bacterial spot, but ...

al., 1994), it was observed that a 3.8-kb HindIII fragment was present in multiple copies in X. campestris pv. juglandis genome when the fragment was used as a probe in the Southern hybridization with HindIII-digested genomic DNA of X. campestris pv. juglandis. To further localize the repetitive sequence, several subclones from the fragment were used as probes to hybridize with HindIII-digested genomic DNA. The Southern hybridization using 2.0-kb PstI-ClaI fragment as a probe showed the same repetitive pattern as 3.8-kb HindIII fragment; in contrast, the probes outside the 2.0-kb fragment hybridized only to a single genomic restriction fragment, indicating that the repetitive sequence was within the 2.0-kb PstI-ClaI fragment. The 2.0-kb fragment was ligated into pBluescript SK(+), resulting in plasmid pISJ12. The insertion sequence-like element in the fragment was named IS1403 afterward.. To isolate a homologous IS from X. campestris pv. campestris XCC1-1, a 0.5-kb AvaII internal fragment of ...

Project C1: The role of selected RNA-binding proteins and small RNAs in bacterial pathogenicity Monika Helm studied biochemistry at the Martin-Luther-University Halle-Wittenberg (2009-2014). As a PhD student Monika investigates potential roles of selected small RNAs (sRNAs) and putative RNA-binding proteins in the virulence of the plant pathogenic bacterium Xanthomonas campestris pv. vesicatoria (Xcv). Although a number of small RNAs were recently discovered in Xcv and virulence functions have been demonstrated for two of them, the targets of the other sRNAs are not known. Furthermore, the involvement of RNA-binding proteins in regulation of small RNA activity in Xcv is not well studied yet. Therefore, Monika aims at the identification and characterization of novel small RNA-binding proteins.. Supervisor: Prof. Ulla Bonas.

The record indicates that prices vary among the end-use industries. Food grades and consumer grades are required to be free from microbacterial contamination. As such, these grades are generally higher priced than oil grades. Xanthan gum is manufactured in only four countries, the United States, Austria, China, and France, all of which export xanthan gum. Xanthan gum is produced from the fermentation of the bacteria strain Xanthomonas campestris. The production process requires maintaining the bacteria strain used for culture; providing carbohydrate, nitrogen, and micronutrient sources to initiate the fermentation process; extracting and refining the xanthan gum from the culture; milling the product into a powder; and finally packaging it for distribution. The production process begins with fermentation of the bacteria. First, selected strains of Xanthomonas capestris must be properly maintained and stored for continuous production. A small amount of the strain is expanded in a shake flask, and ...

Abstract: Host-guest interactions of β-cyclodextrin (β-CD) with enantiomers of ethyl α-chloropropionates ((R/S)-ECPA) were simulated using the quantum mechanics PM3 method. The chiral recognition mechanism of (R/S)-ECPA enantiomers on β-CD was investigated. Modeling results showed that the stabilization of complexes formed by (R/S)-ECPA enantiomers and β-CD were different. (R)-ECPA was located on the cavity wide mouth end of β-CD to form an associated molecule, but (S)-ECPAinserted into the β-CDcavity to forman inclusion molecule. The stabilization energy of the (S)-ECPA and β-CD complex was lower than that of the (R)-ECPA and β-CD complex. The chiral carbon in the ECPA of (R/S)-ECPA and β-CD complexes was close to the C2 and C3 in the glucose unit. The chiral recognition mechanism was thus closely related to the chiral environment provided by C2 and C3 in the glucose unit and the degree of (R/S)-ECPA and β-CD inclusion.. Key words: PM3, Ethyl α-chloropropionate, β-Cyclodextrin, ...

As previously reported, P. aeruginosa genes PA2077 and PA2078 code for 10S-DOX (10S-Dioxygenase) and 7,10-DS (7,10-Diol Synthase) enzymes involved in long-chain fatty acid oxygenation through the recently described oleate-diol synthase pathway. Analysis of the amino acid sequence of both enzymes revealed the presence of two heme-binding motifs (CXXCH) on each protein. Phylogenetic analysis showed the relation of both proteins to bacterial di-heme cytochrome c peroxidases (Ccps), similar to Xanthomonas sp. 35Y rubber oxidase RoxA. Structural homology modelling of PA2077 and PA2078 was achieved using RoxA (pdb 4b2n) as a template. From the 3D model obtained, presence of significant amino acid variations in the predicted heme-environment was found. Moreover, the presence of palindromic repeats located in enzyme-coding regions, acting as protein evolution elements, is reported here for the first time in P. aeruginosa genome. These observations and the constructed phylogenetic tree of the two ...

One of the most damaging diseases of Anthuriums worldwide is Xanthomonas blight caused by X campestris pv. dieffenbachiae. This disease has caused losses in the millions in the Hawaiian cut flower industry and affects production of all types of anthuriums including those grown as potted plants. This disease is characterized by marginal infections which are yellow initially, later turning brown and spreading into the centers of the leaves. Flowers may be affected as well. The bacterium which causes the disease is easily splashed with overhead irrigation or rainfall and is very difficult to control under any growing system which includes overhead irrigation. Use of bactericides has proven a poor control method since many cultivars of the anthurium are sensitive to copper and streptomycin sulfate compounds. Research during the past few years has shown that while fertilizer level affects susceptibility of anthurium to this pathogen it also affects flowering and growth of the plant. The best ...
