Fungi causing powdery mildew on plants of a Botanical Garden in Southern Finland

Fungi that cause powdery mildew on plants are plant pathogenic parasites (<em>Erysiphales</em>) and can significantly reduce the ornamental value of significant yield losses among cultivated plants. In this study, 94 accessions infected with were observed in Kumpula Botanic Garden, Helsinki, Finland, 2015. The taxonomic affiliation species richness fungi investigated. Morphological studies by microscope distinguished only 14 fungal species, whereas further comparisons internal transcribed spacer (ITS) sequences enabled identification 28 species. Hence, ITS sequencing improved reliability determination, as compared use morphological characteristics only. vegetation an area six hectares supported a wide range well hyperparasitic microbes, which may balance impact pathogens host findings study emphasize role botanical gardens protecting biological diversity urban areas.
