Vaczy, Kalman Zoltan and Nemeth, Mark Z. and Csikos, Anett and Kovacs, Gabor M. and Kiss, Levente (2018) Dothiorella omnivora isolated from grapevine with trunk disease symptoms in Hungary. European Journal of Plant Pathology, 150 (3). pp. 817-824. ISSN 0929-1873

Abstract

During a four-year project conducted to identify fungal species associated with grapevine trunk diseases (GTDs) in Hungarian vineyards, two non-sporulating strains isolated from vines exhibiting typical GTD symptoms were identified as Dothiorella omnivore based on their nrDNA ITS and EF1-α sequences. Conidial production of these strains was induced on pine needle medium where production of spermatia has also been observed. Pathogenicity tests confirmed their virulence on potted vines. Dothiorella omnivora is a recently described species of the Botryosphaeriaceae, known to infect hazelnut, ash, walnut, and other woody hosts. This is the first European record of D. omniovora from vines exhibiting GTD symptoms.
