CCOVI to co-lead $6.2-million national research program supporting clean plant program for grapevines

A $6.2-million multi-partner funding commitment will allow Brock University’s Cool Climate Oenology and Viticulture Institute (CCOVI) to support the Canadian Food Inspection Agency (CFIA) and the Canadian Grapevine Certification Network (CGCN-RCCV) to fast-track the certification of grapevine planting material as virus-free.

Under Genome Canada’s Genomic Applications Partnership Program (GAPP), CLEan plAnt extractioN SEquencing Diagnostics (CLEANSED) is a jointly funded initiative between Brock, CFIA, CGCN-RCCV, University of Victoria, Université de Sherbrooke, Genome Canada, Genome BC, Genome Quebec, Ontario Genomics, Agriculture and Agri Food Canada (AAFC), Compute Canada, Conseil des vins du Quebec and Illumina.

CLEANSED utilizes High-Throughput Sequencing (HTS) technology with improved sensitivity to simultaneously detect multiple viruses in a grapevine. This genomic-based solution would replace more than 30 tests currently being performed on grapevines to look for diseases. This one genomic test can speed up the release of virus-free grapevine material from three years to one year (or less), providing rapid access to valuable new varieties. CGCN-RCCV will use this genomic test for testing and monitoring domestically propagated vines, ensuring grape growers have faster and more affordable access to clean vines.

“This funding will allow grape growers to rapidly improve the health of their vineyards and boost the domestic capacity in the supply of much needed virus-free grapevine plant material in Canada,” says CCOVI Senior Scientist Sudarsana Poojari, who is leading the academic team of scientists.

The end users of the research are CFIA and CGCN-RCCV, which will implement CLEANSED to ensure that Canadian grapevines start clean and stay clean. CFIA ensures that grapevine imports, exports and new domestic grapevine varieties for commercialization in Canada are free of regulated viruses and all non-regulated viruses of economic concern, while CGCN will approve and commercialize CLEANSED for testing grapevines in a national domestic clean plant program.

“The CFIA is pleased to co-lead this project that will implement genomic technologies in support of a leading-edge national ‘clean plant’ program and diagnostics at the Sidney Centre for Plant Health. The solid science of the project will help our grape growers to quickly access healthy plants of diverse new varieties, resulting in increased production. Such approaches will be able to facilitate adaptation of Canadian and world agriculture to climate change,” says Jaspinder Komal, Vice-President, Science Branch, CFIA.

The research is a collaborative effort between academia, government, and industry to tackle grapevine virus disease management, which has been identified as the top priority for long-term sustainability of the $9-billion Canadian grape and wine industry.Grape growers currently lose an estimated $23 million per year due to grapevine virus infections. In order to both replace infected material and maintain routine vine replacement and modest expansion, growers currently need access to an estimated 6.7 million affordable, virus-free vines.

High cost and convoluted testing methods, however, are currently hindering the ability of growers to obtain those vines, says CGCN Vice Chair and grape grower Bill Schenck.

“As growers across the country continue to deal with viruses that effect crop quality and vine health, the timing could not be more perfect than now for this project,” he says. “The industry needs to have a Canadian source of clean vines that have been tested for viruses, and a program that can show the vines are true to type.”

He says this work will standardize and validate high throughput sequence (HTS) screening protocols, allowing it to be implemented into a clean grapevine program driven by the industry it benefits.

Mike Rott, Receptor Project Leader and CFIA Scientist, says reducing the time and cost of testing, while at the same time improving sensitivity and accuracy through CLEANSED, is “critical in a highly competitive international market.”

Allowing growers to gain faster access to clean plant material, he adds, both advances the CFIA’s import/ export mandate and allows Canadian growers to develop a made-in-Canada solution to a common goal.

“By working together, we are able to develop a complete, interlinked set of programs that ensures grapevines entering, propagated, sold, grown in Canada and exported, remain disease free.”

CCOVI Director Debbie Inglis says this announcement is the culmination of three years of collaborative work to tackle this priority issue, including previously developed Memorandums of Understanding between CCOVI  and AAFC, CFIA and CGCN to support a clean plant program for grapevines in Canada.

“We’re always looking for rapid, sensitive cost-efficient ways to prove that plant material is devoid from disease, and the application of this research is a milestone for Canada,” she says. “Grapevine is leading the way for the first official clean plant program in the country, where we can be assured that the plants we’re propagating and putting into the ground are free from disease.”

Brock Vice-President, Research Tim Kenyon says that “CCOVI consistently brings together major stakeholders in the grape and wine sector to produce breakthrough policies, programs and services in the industry, generating major contributions to local and national economies.

“This significant grant from Genome Canada shows the confidence stakeholders place in CCOVI’s leadership, research and innovation, one example being the leading-edge CLEANSED virus detection tool.”
