deliberate.release.of.GM.grapevine.plants.in.Europe..Petitions.for.the.release.of.GM.
grapevine.plants.were.submitted.in.France,.Italy,.and.Germany.(Table.5.2)..However,.
GM.grapevine.plants.are.still.quite.a.long.way.from.commercial.use.in.Europe.
The.irst.ield.trial.with.GM.grapevine.plants.(notiication.number.B/FR/94/11/04-
CON).was.carried.out.in.a.vineyard.in.the.Champagne.region.of.France..Plants.of.
18. transgenic. grapevine. lines. of. the. rootstocks. 41B. ( V. vinifera . ×. V. berlandieri ).
and. SO4. ( V. berlandieri . ×. V. riparia ). overexpressing. the. coat. protein. gene. of. the.
Grapevine fanleaf virus .(GFLV).were.established.in.spring.2006. 27 .Nontransformed.
scions.of. V. vinifera cv ..Chardonnay.were.subsequently.grafted.onto.these.rootstocks.
and.tested.for.GFLV-type.symptoms.for.several.years..Furthermore,.the.plants.were.
used.to.study.the.occurrence.of.recombination.events.between.viral.transgene.tran-
scripts.and.ribonucleic.acids.(RNAs).from.indigenous.virus.populations..The.study.
published.by.Vigne.et.al. 27 .provides.evidence.that.the.transgenic.grapevines.did.not.
promote.the.emergence.of.viable.GFLV.recombinants.
Another. grapevine. ield. trial. (notiication. number. B/IT/99/24). has. been. per-
formed.in.Italy.(Figure.5.3)..Transgenic.plants.of.the.grapevine.cultivars.'Thompson.
