Аннотация: Early blight (EB) is a destructive disease affecting potato and tomato plants in Russia, causedby a heterogeneous group of plant pathogenic Alternaria fungi. The current species delimitationin Alternaria sect. Porri with medium to large conidia and a long (filamentous) beak is based onmolecular data. In this study, the ITS, GAPDH, RPB2, TEF1, and Alt a 1 gene regions were analyzedin 41 large-spored Alternaria isolates obtained from diseased potato and tomato plants collected from 13 regions in Russia. Our data revealed five pathogenic species (A. alternariacida, A. grandis, A. linariae, A. protenta, and A. solani). Two species (A. solani and A. linariae) were found to be associated with early blight of tomato. Alternaria linariae and A. protenta were confirmed as the major causal agents of tomato and potato early blight, respectively. There were no phylogenetic groupings among tested Russian Alternaria isolates associated with their locality.
