Surveys carried out to identify bois noir phytoplasmas in grapevine yellows disease outbreaks in vineyards located in Hungary, Serbia, and Italy were performed during summer 2008. Selected samples were studied to check for polymorphism presence in 16S and spacer region, tuf and rpS3 genes. Using several restriction enzymes it was possible to identify different restriction profiles in some of the phytoplasma strains. Collective profiles of all bois noir strains studied were distinguishable from the three stolbur phytoplasmas used as reference strains and preliminary classified in the 16SrXII-A subgroup.

Abstract
Surveys carried out to identify bois noir phytoplasmas in grapevine yellows disease outbreaks in vineyards located in Hungary, Serbia, and Italy were performed during summer 2008. Selected samples were studied to check for polymorphism presence in 16S and spacer region, tuf and rpS3 genes. Using several restriction enzymes it was possible to identify different restriction profiles in some of the phytoplasma strains. Collective profiles of all bois noir strains studied were distinguishable from the three stolbur phytoplasmas used as reference strains and preliminary classified in the 16SrXII-A subgroup.File in questo prodotto:
