Geographic distribution of Bois Noir phytoplasmas infecting grapevines in Croatia

Visual symptom assesment, polymerase chain reaction amplification and restriction fragment length polymorphism analyses were used to detect and identify phytoplasmas infecting grapevines in Croatia. Samples were collected from different viticultural areas in order to examine geographic distribution of phytoplasmas throughout the country. Only phytoplasmas belonging to Bois Noir (subgroup 16SrXII-A or stolbur) were found in vineyards of continental Croatia. The fact that no phytoplasmas were detected in Dalmatia and Istria was in accordance with the absence of grapevine yellows symptoms in these regions.
