Fomitiporia mediterranea (Fmed) is the primary Basidiomycota species causing white rot in European vineyards affected by Esca complex of diseases (ECD). In last few years, an increasing number studies have highlighted importance reconsidering role Fmed ECD etiology, justifying increase research interest related to Fmed’s biomolecular pathogenetic mechanisms. context current re-evaluation binary distinction (brown vs. rot) between decay pathways induced species, our aims investigate potential for non-enzymatic mechanisms adopted Fmed, which typically described as a fungus. Our results demonstrate how, liquid culture reproducing nutrient restriction conditions often found wood, can produce low molecular weight compounds, hallmark “chelator-mediated Fenton” (CMF) reaction, originally brown fungi. CMF reactions redox cycle with ferric iron, generating hydrogen peroxide and ferrous necessary reactants leading hydroxyl radical (•OH) production. These observations led conclusion that radical-generating CMF-like mechanism may be utilized potentially together enzymatic pool, contribute degrading wood constituents; moreover, indicating significant variability strains.

Viticulture worldwide is challenged by grapevine trunk diseases (GTDs). Involvement of arthropods in the dissemination process GTD pathogens, notably esca indicated after detection associated pathogens on arthropod exoskeletons, and demonstration transmission under artificial conditions. The present study first to quantify spore loads via qPCR esca-relevant pathogen Phaeomoniella chlamydospora collected German vineyards, i.e., European earwigs (Forficula auricularia), ants (Formicidae), two species jumping spiders (Marpissa muscosa Synageles venator). Quantification showed acquisition but most carried only low amounts. mycobiome earwig exoskeletons was described for time reveal involvement dispersal GTDs general. Metabarcoding data support potential risk as vectors predominantly Pa. possibly Eutypa lata (causative agent dieback), respective operational taxonomical unit (OTU) assigned genera had relative abundances 6.6% 2.8% total reads, even though with great variation between samples. Seven further GTD-related were at a very level. As various factors influence successful we hypothesize that might irregularly act direct vectors. Our results highlight importance minimizing protecting pruning wounds field.
