AB  - During May 2016, severe blight symptoms were observed in several
raspberry and blackberry fields in Serbia. In total, 22 strains were isolated: 16 from symptomatic raspberry shoots, 2 from asymptomatic
raspberry leaves, and 4 from symptomatic blackberry shoots. Additionally,
eight raspberry strains, isolated earlier from two similar outbreaks, were
included in the study. Pathogenicity of the strains was confirmed on
detached raspberry and blackberry shoots by reproducing the symptoms
of natural infection. The strains were Gram-negative, fluorescent on
King’s medium B, ice nucleation positive, and utilized glucose oxidatively. All strains were levan positive, oxidase negative, nonpectolytic,
arginine dihydrolase negative, and induced hypersensitivity in tobacco
leaves (LOPAT + −−− +, Pseudomonas group Ia). Furthermore, all
strains liquefied gelatin and hydrolyzed aesculin but did not show tyrosinase activity or utilize tartrate (GATTa + + − −). Tentative identification using morphology, LOPAT, GATTa, and ice-nucleating ability
tests suggested that isolated strains belong to Pseudomonas syringae.
The syrB gene associated with syringomycin production was detected
in all strains. DNA fingerprints with REP, ERIC, and BOX primers
generated identical profiles for 29 strains, except for strain KBI 222,
which showed a unique genomic fingerprint. In all, 9 of 10 selected
strains exhibited identical sequences of four housekeeping genes: gyrB,
rpoD, gapA, and gltA. Five nucleotide polymorphisms were found in
strain KBI 222 at the rpoD gene locus only. In the phylogenetic tree
based on a concatenated sequence of all four housekeeping genes,
strains clustered within phylogroup 2 (i.e., genomospecies 1) of the
P. syringae species complex, with pathotype strains of P. syringae pv.
aceris and P. syringae pv. solidagae as their closest relatives. There
was no correlation between genotype and geographic origin, particular
outbreak, host, or cultivar.

AB  - Acidovorax citrulli, the causal agent of bacterial fruit blotch (BFB), is an economically important pathogen of watermelon and related plant species worldwide. In the period 2014–2018, several outbreaks of BFB were observed in major watermelon production regions in Serbia. A total of 43 strains, isolated from symptomatic watermelon tissue, were analyzed by biochemical, pathogenic and molecular tests. Based on the phenotypic characteristics, PCR assay, and 16S rRNA gene sequence analysis, all strains were identified as A. citrulli. A multilocus sequence analysis of the four housekeeping (adk, gyrB, pilT and gltA) and three virulence genes (Aave_1548, avrRx01 and luxR) revealed that studied A. citrulli strains represent the homogeneous population and they clustered together with group II reference strain AAC00-1. Strain affiliation to group II was confirmed by PCR based on the putative type III secretion effector gene and by duplex PCR test. High homogeneity of studied strains was also confirmed by BOX-PCR. Differences were observed for two strains in their pathogenicity as well as susceptibility to copper compounds. Moreover, six major watermelon varieties grown in Serbia showed high sensitivity to the pathogen, while cross inoculation assay revealed that the strains were able to infect other species within the Cucurbitaceae family.

AB  - Bacterial fruit blotch and seedling blight, caused by Acidovorax citrulli, is one of the most destructive diseases of melon and watermelon in many countries. Pathogen-free seed and cultural practices are major pillars of the disease control. However, use of bacteriophages as natural biocontrol agents might also contribute to the disease management. Therefore, we isolated 12 bacteriophages specific to A. citrulli, from phyllosphere and rhizosphere of diseased watermelon plants. The phage strains were characterized based on their host range, plaque and virion morphology, thermal inactivation point, adsorption rate, one step growth curve, restriction fragment length polymorphism (RFLP), and genomic analysis. Transmission electron microscopy of three phage strains indicated that they belong to the order Caudovirales, family Siphoviridae. All phages lysed 30 out of 32 tested A. citrulli strains isolated in Serbia, and did not lyse other less related bacterial species. They produced clear plaques, 2 mm in diameter, on bacterial lawns of different A. citrulli strains after 24 h of incubation. The thermal inactivation point was 66 or 67°C. They were stable at pH 5–9, but were sensitive to chloroform and inactivated in either 5 or 10 min exposure to ultraviolet (UV) light. RFLP analysis using EcoRI, BsmI and BamHI enzymes did not show genetic differences among the tested phages. Adsorption rate and one step growth curve were determined for the Acidovorax phage ACF1. Draft genome sequence of the ACF1 phage was 59.377 bp in size, with guanine-cytosine (GC) content 64.5%, including 89 open reading frames. This phage shared a very high genomic identity with Acidovorax phage ACPWH, isolated in South Korea. Evaluation of systemic nature of ACF1 strain showed that it can be absorbed by roots and translocated to upper parts of watermelon plants where it survived up to 10 days.

AB  - Bacterial stalk soft rot have been repeatedly observed on maize plants in several commercial fields in northern part of Serbia in the period of 1990 to 2014. The occurrence of the disease corresponded with warm weather and increased humidity. Etiological studies of the diseased tissue constantly resulted in isolation of pectolytic bacterial strains. In order to identify the isolated bacteria, twenty-three strains were characterized by morphological, physiolcal, biochemical, and molecular assays. Pathogenicity of the strains was confirmed by Koch's postulates on 1-week-old maize seedlings. The strains were Gram and oxidase-negative, non-fluorescent, pectolytic, facultative anaerobic and caused hypersensitive response (HR) in tobacco leaves. They produced catalase and lecithinase, but did not produce oxidase and arginine dehydrolase. All strains reduced nitrate and grew at 37 degrees C, while variable growth was observed in medium containing 5% NaCl. Phenotypic tests and amplification of the specific 420-bp fragment in PCR assay showed that the strains belong to genus Dickeya. Using ERIC-PCR analysis seven different genetic profiles were obtained, suggesting the presence of genetic diversity in the population of this pathogen in Serbia. Additionally, phylogenetic analysis based on the recA gene sequence analysis indicated that the strains isolated from soft rotted maize belong to Dickeya zeae, leading to the conclusion that this bacterium was the causal agent of stalk soft rot of maize in Serbia.

AB  - Pseudomonas syringae sensu strict , (phylogroup 2; referred to as P. syringae) consists of an environmentally ubiquitous bacterial population associated with diseases of numerous plant species. Recent studies using multilocus sequence analysis have indicated the clonal expansion of several P. syringae lineages, located in phylogroups 2a and 2b, in association with outbreaks of bacterial spot disease of watermelon, cantaloupe, and squash in the United States. To investigate the evolutionary processes that led to the emergence of these epidemic lineages, we sequenced the genomes of six P. syringae strains that were isolated from cucurbits grown in the United States, Europe, and China over a period of more than a decade, as well as eight strains that were isolated from watermelon and squash grown in six different Florida counties during the 2013 and 2014 seasons. These data were subjected to comparative analyses along with 42 previously sequenced genomes of P. syringae stains collected from diverse plant species and environments available from GenBank. Maximum likelihood reconstruction of the P. syringae core genome revealed the presence of a hybrid phylogenetic group, comprised of cucurbit strains collected in Florida, Italy, Serbia, and France, which emerged through genome-wide homologous recombination between phylogroups 2a and 2b. Functional analysis of the recombinant core genome showed that pathways involved in the ATP-dependent transport and metabolism of amino acids, bacterial motility, and secretion systems were enriched for recombination. A survey of described virulence factors indicated the convergent acquisition of several accessory type 3 secreted effectors (T3SEs) among phylogenetically distinct lineages through integrative and conjugative element and plasmid loci. Finally, pathogenicity assays on watermelon and squash showed qualitative differences in virulence between strains of the same clonal lineage, which correlated with T3SEs acquired through various mechanisms of horizontal gene transfer (HGT). This study provides novel insights into the interplay of homologous recombination and HGT toward pathogen emergence and highlights the dynamic nature of P. syringae sensu lato genomes.

AB  - Three PCR methods, referred in this study as,conventional" "nested" and,chromosomal" PCR and suggested for routine detection of Erwinia amylovora in pure culture and plant material, were evaluated according to their specificity and sensitivity. Specificity of PCR methods was analyzed by using 42 strains of E. amylovora, originating from different locations and plant species, with diverse PFGE profiles, representing distant populations of the pathogen. Sensitivity of PCR protocols in pure culture was studied by using nine different concentrations of E. amylovora in sterile ultrapure water as a template in PCR reactions. In order to study inhibitory effect of plant DNA and other inhibitors on sensitivity of the three PCR methods bacterial dilutions were mixed with plant macerate of pear, apple and quince prior to the PCR reaction. In specificity assays, tested PCR protocols were able to detect all E. amylovora strains regardless of the host of the strain, its origin or PFGE group, indicating primer specificity. On the other hand, sensitivity among tested methods varied, depending on bacterial concentration and selected plant material used in the PCR. When working with pure cultures nested PCR showed the greatest sensitivity by detecting 1.9 bacterial cells per PCR reaction, followed by detection limit of 9.5 cells per PCR reaction with conventional PCR and 1.9.105 cells/PCR reaction with chromosomal PCR. In spiked samples plant inhibitors either did not affect or they decreased the sensitivity of the PCR reaction, depending on the protocol and/or type of plant macerate. In our experiments, inhibitors from pear and quince macerates did not affect sensitivity of nested PCR, while apple macerate reduced its sensitivity by a factor of 10. Conventional PCR protocol was able to detect 95 cells/PCR reaction in pear and apple macerate, but only 9.5.103 cells/PCR in quince macerate. Greatest decrease in sensitivity of the PCR method was observed in spiked samples with chromosomal PCR since bacterial DNA was not detected in each of the spiked samples. Our research shows that all three PCR protocols are specific for detection of E. amylovora, but nested PCR proved to be most sensitive when working with pure cultures and plant material.

AB  - Carrot psyllid Bactericera trigonica belongs to the family Triozidae, superfamily Psylloidea, order Hemiptera. Together with onion psyllid (B. tremblayi) and potato psyllid (B. nigricornis), it is a member of the complex Bactericera nigricornis Foerster with morphologically and bioecologically very similar species. It was originally described by Hodkinson (1981) as Trioza trigonica based on the analysis of adults collected from the carrots in Portugal, Italy, Cyprus, Turkey, Egypt and Iran. Later it has been transferred to the genus Bactericera together with the two other species from this complex. Adults and larvae B. trigonica, feed on carrot leaf and other Apiaceae. If they appears in large number, they can lead to chlorosis and leaf yellowing, which causes a yield reduction. Besides direct damage, its vector role of bacteria “Candidatus Liberibacter solanacearum” has been determined, which leads to root proliferation and weakening of plants from Apiaceae family due to chlorosis. Ca. Liberibacter solanacearum has been known in North Africa and New Zealand for a long time on plants from Solanacae family, potato in the first place, while in Europe it has been determined on carrot and cellery for the first time, with B. trigonica as its vector. The presence, biology and harmfulness of B. trigonica in the region of Serbia were studyed in the period from 2014 to 2017. It was found in 2014 for the first time and since then, its presence has been determined in all researched localities, during the whole vegetative period of carrot. Besides carrot, B. trigonica has been registered on celery, parsley and wild carrot as well. It has a several generations per year, overwintering as adults.
AB  - Mrkvina lisna buva Bactericera trigonica pripada familiji Triozidae, nadfamiliji Psylloidea, redu Hemiptera. Zajedno sa lukovom lisnom buvom (B. tremblayi) i krompirovom lisnom buvom (B. nigricornis) pripada kompleksu Bactericera nigricornis Foerster, u morfološkom i bioekološkom smislu veoma sličnih vrsta. Opisana je 1981. godine kao Trioza trigonica na osnovu analize imaga sakupljanih sa mrkve iz Portugalije, Italije, Kipra, Turske, Egipta i Irana. Kasnije je prebačena u rod Bactericera zajedno sa druge dve vrste ovog kompleksa. Imaga i larve se hrane na listu mrkve i drugih štitonoša. Ukoliko se jave u povećanoj brojnosti mogu dovesti do hloroze i žućenja lista, što ima za posledicu smanjenje prinosa. Pored direktnih šteta, utvrđena je njena vektorska uloga fastidiozne bakterije «Candidatus Liberibacter solanacearum», koja na biljkama iz familije Apiaceae dovodi do proliferacije korena i hlorotičnog slabljenja. Ca. L. solanacearum je odavno poznata u Severnoj Americi i Novom Zelandu na biljkama iz familije Solanacae, prevashodno na krompiru, a u Evropi je prvi put utvrđena na mrkvi i celeru, a B. trigonica kao njen vektor. U periodu od 2014. do 2017. godine proučavano je prisustvo, biologija i štetnost B. trigonica na području Srbije. Prvi put je registrovana 2014. godine i od tada je utvrđeno njeno prisustvo u svim lokalitetima istraživanja tokom celog vegetacionog perioda mrkve. Pored mrkve, B. trigonica je registrovana na celeru, peršunu i divljoj mrkvi. U toku godine ima veći broj generacija, prezimljava u stadijumu imaga na skrovitim mestima.

Besides carrot, B. trigonica has been registered on celery, parsley and wild carrot as well. It has a several generations per year, overwintering as adults., Mrkvina lisna buva Bactericera trigonica pripada familiji Triozidae, nadfamiliji Psylloidea, redu Hemiptera. Zajedno sa lukovom lisnom buvom (B. tremblayi) i krompirovom lisnom buvom (B. nigricornis) pripada kompleksu Bactericera nigricornis Foerster, u morfološkom i bioekološkom smislu veoma sličnih vrsta. Opisana je 1981. godine kao Trioza trigonica na osnovu analize imaga sakupljanih sa mrkve iz Portugalije, Italije, Kipra, Turske, Egipta i Irana. Kasnije je prebačena u rod Bactericera zajedno sa druge dve vrste ovog kompleksa. Imaga i larve se hrane na listu mrkve i drugih štitonoša. Ukoliko se jave u povećanoj brojnosti mogu dovesti do hloroze i žućenja lista, što ima za posledicu smanjenje prinosa. Pored direktnih šteta, utvrđena je njena vektorska uloga fastidiozne bakterije «Candidatus Liberibacter solanacearum», koja na biljkama iz familije Apiaceae dovodi do proliferacije korena i hlorotičnog slabljenja. Ca. L. solanacearum je odavno poznata u Severnoj Americi i Novom Zelandu na biljkama iz familije Solanacae, prevashodno na krompiru, a u Evropi je prvi put utvrđena na mrkvi i celeru, a B. trigonica kao njen vektor. U periodu od 2014. do 2017. godine proučavano je prisustvo, biologija i štetnost B. trigonica na području Srbije. Prvi put je registrovana 2014. godine i od tada je utvrđeno njeno prisustvo u svim lokalitetima istraživanja tokom celog vegetacionog perioda mrkve. Pored mrkve, B. trigonica je registrovana na celeru, peršunu i divljoj mrkvi. U toku godine ima veći broj generacija, prezimljava u stadijumu imaga na skrovitim mestima.",

AB  - Cucurbits production has a long tradition in our country. In some parts of the country, cucumber, watermelon and melon are the most important agricultural crops. High yield and good profit are often compromized by various biotic and abiotic factors. In years with favorable weather conditions cucurbit bacterial diseases can cause serious damage. This paper describes major bacterial diseases of cucurbit plants, such as angular leaf spot caused by Pseudomonas syringae pv. lachrymans, bacterial fruit blotch caused by Acidovorax citrulli, bacterial spot caused by Xanthomonas campestris, bacterial wilt caused by Erwinia tracheiphila and cucurbit yellow wine disease caused by Serratia marcescens, relatively new and invasive disease across the United States. In addition, bacterial leaf spot, caused by Pseudomonas syringae pv. syringae and Pectobacterium carotovorum subsp. carotovorum, inducing bacterial soft rot, are becoming more important in cucurbit production worldwide.
AB  - Biljke familije Cucurbitaceae se dugi niz godina gaje širom naše zemlje. U pojedinim krajevima, proizvodnja krastavca, lubenice i dinje predstavlja osnovni izvor prihoda za mnoga poljoprivredna domaćinstva. Visok prinos i ekonomsku dobit često ugrožavaju različiti biotski i abiotski faktori. U godinama sa uslovima povoljnim za nastanak infekcije, bakteriozna oboljenja mogu prouzrokovati velike gubitke. U ovom radu predstavljene su najznačajnije bakterioze biljaka familije Cucurbitaceae kao što su uglasta pegavost lišća krastavca, prouzrokovana bakterijom Pseudomonas syringae pv. lachrymans; bakteriozna mrljavost plodova lubenice, čiji je prouzrokovač Acidovorax citrulli; zatim bakteriozna pegavost koju prouzrokuje Xanthomonas cucurbitae; bakteriozna uvelost krastavca prouzrokovana vrstom Erwinia tracheiphila i žutilo vreža, čiji je prouzrokovač Serratia marcescens.

AB  - Candidatus Liberibacter solanacearumis a gram-negative bacterium restricted to plant phloem, associated with economically important diseases such as potato zebra chip and yellow decline and with vegetative disorders in carrots and celery. Over the past decade, the zebra chip disease resulted in major economic loses in the potato production of U.S.A., Mexico, Central America and New Zealand. Outbreaks of yellow decline and vegetative disorders in carrot and celery crops have been reported recently in geographically distant areas and the countries of Europe (Finland, Sweden, Norway, Spain, France and Germany). The infected plants showed symptoms including yellow, bronze or red leaf discoloration, reduced size of main root and lateral root proliferation. Given the importance of carrot production in Serbia, the goal of this review paper is to raise awareness about the disease occurrence and distribution, discuss the main characteristics of this relatively unknown pathogen, its detection and identification, epidemiology, symptomatology and disease management, before this emerging plant pathogenic organism reaches our country.

AB  - Continuous use of copper-based treatments and antibiotics in pear and apple protection programs may result in appearance of copper or antibiotic resistant strains of Erwinia amylovora. In order to determine the potential occurrence of copper or/and antibiotic resistance in Serbia we studied in vitro effect of different concentrations of copper sulfate, streptomycin and kasugamycin on development and growth of 40 E. amylovora strains originating from this region. Filter sterilized solution of the bactericides was added to the NA medium after sterilization to a final concentration of 100 and 200 ppm, respectively, followed by spot inoculation of each strain on the medium. None of the strains developed on NA amended with 100 or 200 ppm of streptomycin or kasugamycin. Our study showed that, despite the potential exposure to the antibiotics, E amylovora strains from Serbia did not develop resistance to streptomycin or kasugamycin. On the other hand, all strains had normal growth on NA amended with 100 ppm of copper sulfate indicating certain level of resistance to copper ions. At 200 ppm, 28 strains formed colonies of normal size and appearance, while 12 strains had smaller colonies with reduced growth. This might be due to the extensive and frequent use of copper-based compounds to control fire blight in Serbia.

AB  - Grapevine crown gall caused by Allorhizobium vitis, or less frequently by Agrobacterium tumefaciens complex and Rhizobium rhizogenes, may seriously impact production in nurseries and vineyards worldwide. Although rapid and efficient detection and identification of tumorigenic bacteria is facilitated by PCR-based methods, high genetic diversity of these pathogens may hinder use of these methods in the disease diagnosis. Therefore, reliability of 11 primer pairs targeting fragments located on Ti plasmid or chromosomal DNA was tested on extensive collection of All. vitis, A. tumefaciens complex and R. rhizogenes strains isolated from grapevine throughout the world. Only primers VCF3/VCR3 targeting virC gene located on Ti plasmid clearly and accurately identified all tested tumorigenic strains associated with grapevine crown gall. Moreover, this primer pair coupled with primers specific for chromosomal pehA gene (PGF/PGR) in duplex PCR, may be recommended as the method of choice for routine preliminary identification of tumorigenic strains and differentiation of All.

This pathogen causes signifi cant economic losses by reducing the yield and quality of potato crops. It is widespread in commercial potato fi elds in USA, Mexico, Central America ,New Zealand. CaLsol can also affect other solanaceous crops, including tomato, pepper, eggplant, tamarillo. Recently, it was detected in several Northern European countries in carrot and celery crops. Chips made from zebra chip-infected tubers show dark stripes that become more visible upon frying, and are therefore commercially unacceptable. Bearing in mind the importance of potato production in our country, it is necessary to raise the awareness about the disease occurrence and distribution.
AB  - Među najznačajnijim štetnim organizmima koji ugrožavaju proizvodnju krompira od nedavno se ubraja fastidiozna bakterija 'Candidatus Liberibacter solanacearum' (CaLsol). Ovaj patogen odgovoran je za pojavu novog oboljenja krompira pod nazivom 'zebrasti čips' (ZČ), rasprostranjenog u proizvodnim područjima Amerike i Novog Zelanda. Iako je glavni domaćin patogena krompir, ozbiljne štete zabeležene su i na biljkama paprike, paradajza i drugim gajenim vrstama iz familije Solanaceae. U Evropi isti patogen nedavno je otkriven na obolelim biljkama mrkve i celera. Na krompiru, kao posledica infekcije dolazi do smanjenja prinosa zaraženih biljaka, a najznačajnije štete nastaju usled pojave simptoma na krtolama i gubitka njihove tržišne vrednosti. S obzirom na ekonomski značaj proizvodnje krompira u našoj zemlji, kao i na mogućnost unošenja bakterije putem vegetativnog sadnog materijala, postoji opravdana zabrinutost od širenja ovog patogena na teritoriji naše zemlje.

AB  - During the summer of 2014, watermelon producers in the north of Serbia (Srem district), observed the occurrence of irregularly shaped, water-soaked lesions on mature watermelon fruits indicating possible bacterial nature of the disease. Bacteria were isolated from symptomatic samples and identified as Acidovorax citrulli, previously described as a causal agent of bacterial fruit blotch. In the past few years, this pathogen caused considerable damage to the watermelon industry of the United States where, in some commercial production sectors, the loss of marketable fruit reached 90%. In Serbia, it is considered a quarantine pathogen and was not recorded until 2014.

AB  - During the last 3 years, crown gall disease was observed in some young raspberry plantations throughout Serbia, causing considerable economic losses. Based on biochemical and physiological tests, PCR targeting the 23S rRNA gene, and 16S rRNA and recA gene sequence analysis, at least two different species were identified as causal agents of disease. Out of 14 strains isolated from raspberry tumors, 12 were identified as tumorigenic Rhizobium rhizogenes, one belonged to Agrobacterium tumefaciens genomic species G8, while the remaining strain formed a separate phylogenetic lineage within A. tumefaciens species complex, different from all known genomic species. All strains investigated harbored nopaline-type of Ti plasmid and showed identical pathogenic properties by inoculating several test plants. However, they were divided into two genetic groups based on PCR-RFLP analysis of Ti plasmid virA-virB2 region. Furthermore, total of nine unique ERIC-PCR profiles were identified among the strains studied. Although strains of R. rhizogenes exhibited similar ERIC-PCR profiles, they were differentiated into six distinct genetic groups. Based on the fact that some genetic groups were composed of strains originating from different geographic areas, it can be assumed that they have a common origin and were probably disseminated by movement of infected plant material.

AB  - Two plant-tumorigenic strains KFB 330(T) and KFB 335 isolated from galls on raspberry (Rubus idaeus) in Serbia, and a non-pathogenic strain AL51.1 recovered from a cherry plum (Prunus cerasifera) tumor in Poland, were genotypically and phenotypically characterized. Phylogenetic reconstruction based on 16S rDNA placed them within the genus Agrobacterium, with A nepotum as their closest relative. Multilocus sequence analysis (MLSA) based on the partial sequences of atpD,glnA, gyrB, recA and rpoB housekeeping genes suggested that these three strains represent a new Agrobacterium species, that clustered with type strains of A. nepotum, A. radiobacter, "A fabrum" and A. pusense. This was further supported by average nucleotide identity values ( lt 92%) between the whole genome sequences of strain KFB 3301 and related Agrobacterium species. The major cellular fatty acids of the novel strains were 18:1 w7c (72.8-77.87%) and 16:0 (6.82-8.58%). Phenotypic features allowed their differentiation from closely related species. Polyphasic characterization showed that the three strains represent a novel species of the genus Agrobacterium, for which the name Agrobacterium arsenijevicii sp. nov. is proposed. The type strain ofA. arsenijevicii is KFB 330T (=CFBP 8308(T) = LMG 28674(T)).

AB  - Potato production provides one of the main sources for food production, processed either at home or by the industry. Plant diseases are often limiting factor in cultivation of this crop, leading to reduction of yield and tuber quality. Zebra chip disease, caused by a floem-limited bacterium, belonging to the genus Candidatus Liberibacter, is a new, economically important disease of potato and other solanaceous plants. It is widespread in commercial potato fields in USA, Mexico, Central America, New Zealand, and was recently reported in Europe. The disease reduces yield, but most significant damage occurs due to the symptom development on tubers and loss of their marketability. Given the importance of potato production in our country, the goal of this paper is to raise the awareness about the disease occurrence and distribution, discuss the main characteristics of this relatively unknown pathogen, detection and identification methods necessary for the successful and timely diagnosis, epidemiology, symptomatology and disease management.
AB  - Krompir je biljna vrsta čija proizvodnja ima veoma značajnu ulogu u obezbeđivanju hrane, a takođe i sirovine za industrijsku preradu. Pojava štetnih organizama neretko predstavlja ograničavajući faktor gajenja ove biljke, jer dovodi do smanjenja prinosa i pogoršanja kvaliteta krtola. Oboljenje nazvano zebrasti čips, koje prouzrokuje fastidiozna bakterija iz roda Candidatus Liberibacter, je novo, ekonomski značajno oboljenje biljaka iz familije Solanaceae, čiji je glavni domaćin krompir. Patogen, takođe, zaražava i srodne vrste kao što su paradajz i paprika. Ovo destruktivno oboljenje rasprostranjeno je u proizvodnim područjima Amerike, Novog Zelanda, a nedavno je otkriveno i na evropskom kontinentu. Kao posledica infekcije, dolazi do smanjenja prinosa zaraženih biljaka, dok najznačajnije štete nastaju usled pojave simptoma na krtolama i gubitka njihove tržišne vrednosti. S obzirom na značaj proizvodnje krompira, paradajza i paprike u našoj zemlji, cilj ovog rada je da se ukaže na pojavu i rasprostranjenost oboljenja, glavne karakteristike ovog malo poznatog patogena, metode detekcije i identifikacije neophodne za pouzdanu i pravovremenu dijagnozu oboljenja, epidemiologiju, simptomatologiju i mere zaštite.

abstract = "Potato production provides one of the main sources for food production, processed either at home or by the industry. Plant diseases are often limiting factor in cultivation of this crop, leading to reduction of yield and tuber quality. Zebra chip disease, caused by a floem-limited bacterium, belonging to the genus Candidatus Liberibacter, is a new, economically important disease of potato and other solanaceous plants. It is widespread in commercial potato fields in USA, Mexico, Central America, New Zealand, and was recently reported in Europe. The disease reduces yield, but most significant damage occurs due to the symptom development on tubers and loss of their marketability. Given the importance of potato production in our country, the goal of this paper is to raise the awareness about the disease occurrence and distribution, discuss the main characteristics of this relatively unknown pathogen, detection and identification methods necessary for the successful and timely diagnosis, epidemiology, symptomatology and disease management., Krompir je biljna vrsta čija proizvodnja ima veoma značajnu ulogu u obezbeđivanju hrane, a takođe i sirovine za industrijsku preradu. Pojava štetnih organizama neretko predstavlja ograničavajući faktor gajenja ove biljke, jer dovodi do smanjenja prinosa i pogoršanja kvaliteta krtola. Oboljenje nazvano zebrasti čips, koje prouzrokuje fastidiozna bakterija iz roda Candidatus Liberibacter, je novo, ekonomski značajno oboljenje biljaka iz familije Solanaceae, čiji je glavni domaćin krompir. Patogen, takođe, zaražava i srodne vrste kao što su paradajz i paprika. Ovo destruktivno oboljenje rasprostranjeno je u proizvodnim područjima Amerike, Novog Zelanda, a nedavno je otkriveno i na evropskom kontinentu. Kao posledica infekcije, dolazi do smanjenja prinosa zaraženih biljaka, dok najznačajnije štete nastaju usled pojave simptoma na krtolama i gubitka njihove tržišne vrednosti. S obzirom na značaj proizvodnje krompira, paradajza i paprike u našoj zemlji, cilj ovog rada je da se ukaže na pojavu i rasprostranjenost oboljenja, glavne karakteristike ovog malo poznatog patogena, metode detekcije i identifikacije neophodne za pouzdanu i pravovremenu dijagnozu oboljenja, epidemiologiju, simptomatologiju i mere zaštite.",

AB  - Serious outbreaks of grapevine crown gall disease were observed in major Serbian viticultural regions during the last five years. Tumorigenic Agrobacterium vitis was identified as a causal agent by using conventional bacteriological and molecular tests. The 36 studied strains of A. vitis showed homogeneous biochemical and physiological characteristics, but were heterogeneous in their pathogenic properties, especially on tomato and sunflower. Furthermore, genetic differences related to chromosomal and plasmid DNA were observed. The Ti plasmid of 35 strains was classified as the octopine/cucumopine (O/C) type, whereas one was classified as the vitopine (V) type. The O/C strains were further divided into O/C-1 and O/C-2 groups based on PCR analysis. Moreover, the sequence analysis of the 16S-23S rRNA ITS region provided robust and precise delineation of studied strains. Although a high level of genetic diversity in A. vitis strains from Serbia was revealed by using this approach, their genotypic relatedness with the strains from other countries suggested their common origin. Also, association between the chromosomal and plasmid DNA was determined for some phylogenetic groups and clusters.
