Fungal Community Taxa Differ in Diversity and Number between Live and Dead Prunus serotina Ehrh. Wood in a Protected Forest within Its Secondary Range of Distribution

Prunus serotina is an important invasive plant species in Poland. It was introduced to European forests, even places currently protected by law, such as national parks. One major factor contributing the spread of this lack infecting pathogens and incomplete knowledge about relationship between microorganisms. This study aimed identify fungal communities collected from freshly cut stumps live dead black cherry tree specimens growing a forest. The main working hypotheses were follows: (i) inhabiting wood living trees will differ diversity number taxa; (ii) saprotrophic fungi dominate stumps. applied Illumina sequencing based on amplification ribosomal ITSI region. average sequences (OTU) obtained analysis 101,758, while that 94,150. These belonged 312 taxa, among which 254 isolated 171 trees. Among saprotrophs trees, following identified: Stereum rugosum, Ganoderma adspersum, G. applanatum, Peniophora cinerea, Ascocoryne cylichnium. On other hand, Cytospora leucostoma Botrytis cinerea most abundant species. differed abundance thus confirming our hypothesis. results research conducted area indicate can be naturally colonized many pathogen further limit its expansion.
