  3. 3. VITISENS project overviewhttp://www.isppweb.org/nlmar11.aspwww.flavescencedoree.orgFlavescence Dorée phytoplasma• A unicellular organism that lives and grows in the sap of grapevines• Responsible for the most destructive phytoplasma disease of grapevines• Severely damages plant productivity• Transmitetd by the leafhopper Scaphoideus titanius, as it movesbetween vines to feedThe occurrence of FD disease• Catastrophic in France and Italy.• Incidence is rising rapidily in other EU countries inrecent years, showing a clear epidemic pattern of spread• Straining grape and wine producers alreadystrugglying to maintain competitiveness withregard to New Word and Asian producers.www.vitisens.eu
  4. 4. VITISENS project overviewVITISENS proposes a portable handheld device answering to the need of wine producerand wine plant nursery SMEs to perform rapid in-field tests to determine the presence ofthe Flavescense Doree phyotplasma in grapevines by means of an innovative integration ofextraction, amplification and detection steps.Current detection procedure: visual inspection• This approach can not detect latent infections.• Leaf symptoms are mainly evident in the summer and are often misleading due to the diversityshown in different grapevine varieties and due to the similarity with symptoms shown by otherphysiological alterations or by diseases caused by other pathogensVITISENS consortium believe that containment and even eradication of the disease is feasible butonly if timely and accurate detection of the FD is achieved and control measures are imediatelyapplied.www.vitisens.eu

  6. 6. Scientific and Technological objectivesScientific objectives: To fill the gaps in the current state-of-the-art in FD detection methodswhile improving their specificity and sensitivity through the combination of molecularmethods and fluorescence detection technologies, as well as to innovate far beyond thecurrent laboratory detection methods.Technological objectives: to develop a homogeneous, simple, rapid, accurate, hand heldand cost-effective diagnostic tool for detecting the Flavescence doreé phytoplasma withcost below €1,000 per unit and €10 per test.VITISENS device must integrate the three required steps to perform sensitive and accuratedetection of nucleic acids: extraction, amplification of specific sequences and detection.www.vitisens.eu
  7. 7. Main Outcomes of the project. Market SurveyDuring the first 6 months of the project, a questionnaire was developed by the partners togather information on the market and end-users needs to define the final VITISENSspecifications.In order to better understand and interpret the end-users answers, it was first necessary toknow if they were located in a region affected by Flavescence dorée or not. Among thecollected responses, it appears that 56% of the end-users questioned are based in regionswhere FD is present.Percentage of FD impacted or not end-users country by countrywww.vitisens.eu
  8. 8. Main Outcomes of the project. Market SurveyMoney spent on fighting Flavescence DoreéFlavescence dorée is a sensitive topic due to its quarantine status. Therefore end-users aresometimes afraid either to communicate about FD in their vineyards or of the dissemination ofthe information given by them. This part of the questionnaire was not answered by the end-users.Nevertheless, useful information was obtained from governmental organizations in France, since anational survey of FD impact has been carried out in the past years and is updated every year. Itappears that 30 million € are spent in France to fight against FD (insecticide, material, labourhours, etc…). Moreover, we also learnt that €150,000 were spent in 2010, only for Flavescencedorée analysis.Current detection method used, FDtesting?56% of them do not perform testsNotice: FD analysis are notmandatory in regions not affected byFD.www.vitisens.eu
  9. 9. Main Outcomes of the project. Market SurveyCurrent detection method used, which FD detection/analysis?Visual inspection of symptoms is the most common method used. Amongthe end-users, more than 70% observe the symptoms and 33% send theirsamples to laboratories.When we focus on the end-users who declared doing FD tests, among the71% who observe symptoms, 67% also test FD in laboratory.Current detection method used, main end-users?The main end-users performing tests are the inspectors themselves. The other significant end-usersseem to be the nurseries even if the number of tests seems to be quite low (just for import control).Current detection method used, time to results?Since the disease spreads quite rapidly, results are needed as soonas possible, and over 90% of the end-users have to wait between 2and 3 weeks for the results. That’s why 63 % of end-users thinkthat the current used method is not quick enoughwww.vitisens.eu
  10. 10. Main Outcomes of the project. Market SurveyPrice sensitivity, maximum price per test?As the fight against FD is managed by governmental authorities, this is thebest source for global information regarding price of FD analyses.60 % of the end-users doing FD testing pay between 50 and 100 Euros for atest. As a rule, every interviewed person found it too expensive.Interest in a new detection method?Among the end-users questioned, 65% of them (within the high and the quite high interest levels)stated that it would be necessary to have a quick, cost effective and reliable field diagnostic test forFlavescence dorée.Where would you like to perform the test/diagnosis?Half of the end users answered directly “in the field” and the other half “in the office” or similarfacilities. Inspectors, due to specific prevention campaign, will have to test several samples in a field.For them, it is more convenient to collect all the samples and analyse them later. They estimate thateven if we propose a result of the analysis in 30 minutes, the running time of the analysis will be stilltoo long to perform all the tests in the vineyard. However, wine growers or nurseries will only want toconfirm visual symptoms on few samples, therefore, they prefer the in-field solution.www.vitisens.eu
  11. 11. Main Outcomes of the project. Market SurveyVITISENS important featuresConclusionsEnd-users located in the most FD-impacted countries were the most sensitized to the disease and theneed to control it.63% of the end-users doing FD tests thought that their current detection method is not quick enough.60 % of them paid between 50 and 100 Euro and found it too expensive, and for the others, theanalyses had been performed by legal authorities. When asked directly we found that 65% of thequestioned end-users thought that VITISENS would be useful to them.www.vitisens.eu
  12. 12. Main Outcomes of the projectWork carried out during the project by RTD partners to develop the VITISENSdevice Sample treatment protocol has been developed by NIB adapted to the fieldconditions DNA extraction method was developed by CRIC specific for FD amplificationand further detection using laboratory new methods (LAMP) adapted for in fieldconditions performed by FERA. Special instrumentation for optical detection and temperature control systemwas developed by CRIC to carry out the tests CRIC has also design the portable device as well as the disposable cartridgewhere the sample must be introduced.VITISENSDiagnostickitVITISENSReader kitwww.vitisens.eu
  13. 13. Main Outcomes of the projectInnovative amplification method – Loop-Mediated Isothermal Amplification (LAMP)Japanese company Eiken Chemical Co. Developed the novel nucleid acid isothermal amplificationmethod. The method has already been used under laboratory conditions for the detection of severalpathogens with highly successful and satisfactory results.By defining four to six primers specifically for six to eight distinct regions on the targetgene, extremely high specificity is provided. By incubating all these reagents in a singletube, sequences from either RNA or DNA are selectively amplified.The amplification takes placed at constant temperature of 65ºC, therefore a heating stage is requiredin the VITISENS reader.Watch videoEiken Genome Co., Ltd.www.vitisens.eu
  14. 14. Main Outcomes of the projectVITISENS detection method – Optical detectionFluorescence technique is used to detect the resulting product obtained from the LAMP reaction.Specific fluorescence dyes are used together with the LAMP reagents. These dyes will emitfluorescence when binding double stranded DNA, what means when the sample is infected. Emissionlevels are measured by the VITISENS optical detection system and results are immediately showed onthe LCD screen.Reaction chamber –detection pointwww.vitisens.eu
