First report of flavescence dorée-related Phytoplasma in a productive vineyard in Germany
Plant Disease 105 (11 - 0330)
Abstract: During 2020, grapevine plants grown in Rheinhessen, Germany were observed with symptoms of leaf rolling and discoloration, incomplete lignification, and black pustules arranged in lines along the shoots. Diseased shoots were black and necrotic in December. DNA was extracted from symptomatic plants and analyzed by PCR using phytoplasma specific primers. The presence of a phytoplasma was demonstrated in the symptomatic plants and the PCR product was cloned and sequenced. Sequence analysis showed the presence of a phytoplasma belonging to flavescence dorée, 16SrV phytoplasma group.
