Other grapevine viruses of lesser economic importance

Abstract

Symptomatic vines infected by Alfalfa mosaic virus (AMV), Grapevine angular mosaic virus (GAMV), Grapevine line pattern virus (GLPV), Raspberry bushy dwarf virus (RBDV), and Grapevine Roditis leaf discoloration-associated virus (GRLDaV) have been reported from different European countries, whereas infections by Grapevine berry inner necrosis virus (GINV) and Summer grape latent virus (SGLV) were found in Japan and the USA, respectively. These viruses have a limited geographical distribution and have only a relevant economic impact regionally, except for a few of them (RBDV, GRLDaV, and GINV). Medium- and long-distance dissemination occurs via infected propagative material, whereas local spread is mediated by the eriophyid mite Colomerus vitis (GINV) and, as hypothesized but not proven, by the nematode Longidorus juvenilis (RBDV).
