Genetic structure and variability of virus populations in cross-protected grapevines superinfected by Grapevine fanleaf virus Inra
Vigne, E.; Marmonier, A.; Komar, V.; Lemaire, O.; Fuchs, M..
Recombination was assessed in a vineyard site in which grapevines cross-protected with mild strains GHu of Grapevine fanleaf virus (GFLV) or Ta of Arabis mosaic virus (ArMV) were superinfected with GFLV field isolates following transmission by the nematode vector Xiphinema index. The genetic structure and variability within RNA2 of isolates from grapevines co-infected with GFLV field isolates and either GFLVGHu or ArMV-Ta were characterized to identify intra- and interspecies recombinants. Sequence analysis and phylogenetic relationships inferred intraspecies recombination among GFLV field isolates but not between field isolates and GFLV-GHu. SISCAN analysis confirmed a mosaic structure for two GFLV field isolates for which recombination siteswere located...

Multiple interspecies recombination events within RNA2 of Grapevine fanleaf virus and Arabis mosaic virus Inra
Vigne, E.; Marmonier, A.; Fuchs, M..
Abstract Sequence alignments and SISCAN analysesinferred multiple interspecies recombination events withinRNA2 of strains GHu of Grapevine fanleaf virus (GFLV)and Ta of Arabis mosaic virus (ArMV), two closely relatedsubgroup A nepoviruses in the family Comoviridae.Interspecies recombination events were identified in the 50untranslated region, the putative homing protein andmovement protein genes but not in the coat protein geneand 30 untranslated region. These findings suggest adynamic relationship between GFLV and ArMV, and adifferential selection pressure on RNA2-encoded proteinswith constraints in terms of function and co-adaptation thatlimit interspecies recombination to certain gene segments.
