Five speakers take a closer flavour at the subject area latterly during a knowledge session on radical - sore detection technique at Naktuinbouw . Do the techniques propose chance or risks , was the interrogation addressed by Maaike Bruinsma of NVWA , Sven Berendsen of Rijk Zwaan , Harrie Koenraadt of Naktuinbouw , René van der Vlugt of WUR and Harry Vennema of RIVM .
Molecular detection techniques have helped enormously in testing veggie ejaculate for the absence of disease , Sven portion out on behalf of breeding ship’s company Rijk Zwaan . Those run are postulate is the for external trade . Indirect technique do not name between viruses that can cause infection and non - infectious ' enviromental ' RNA , causing unneeded rejection of seed lots . He lamented . ‘Shouldn’t direct method , such as plant pathogenicity indicator tests that detect only infectious virus , be trust on more in risk analysis ? ' , was a question he asked . Besides historical data , this could possibly be support with digital PCR to determine the presence or absence seizure of amply genomic RNA in a sample .
With the emergence of High Throughput Sequencing ( HTS ) technique , it is now possible to ' discover ' a hoi polloi of viruses in flora and industrial plant stuff , René share on behalf of WUR . Often , these computer virus go unnoticed because they do not do symptoms . But such discoveries do raise all sort of questions about the potential phytosanitary risks . In a sub - project PPS Phytosanitary Important for the Netherlands , inquiry was carry out into the viruses come in non - European tuberous plants . On the example of Mashua ( Tropaeolum tuberosum ) , those computer virus findings are discussed , as well as crucial follow - up questions .
political economy and politicsBoth speakers had an eye for the economical side of the virus issue ( not eliminate seminal fluid unnecessarily ) and specifically René also for the latent hostility between scientists and policymakers . " A virologist takes into account how infective and infectious a new virus is . A policymaker goes more for ruling out any risk and point a raw virus on the quarantine lean for refuge reasons . " As happened with ToBRFV , for case . Meanwhile , the Netherlands is keen to get rid of thatQ status , now that the virus is now far-flung anyway . Q condition was also already underdiscussionin the US .
" It is important to discover a balance between these two extremes , " René thinks . " To keep it workable , we call for to decide with expert which viruses we will investigate further . One approach here could be to look specifically at potential peril on frequently swop crops with gamey economic importance , " he suggests in a pre - publishing of an consultation for Naktuinbouw magazineBuitenstebinnen .
