While Hymenoscyphus fraxineus causes dieback of the European ash (Fraxinus excelsior), flowering ash (F. ornus) appears resistant to the pathogen. To date, contributions of endophytic fungi to host resistance are unknown. The following hypotheses were tested: (i) endophytic fungi enhance the resistance of F. excelsior to the pathogen; (ii) resistance of F. ornus relies on its community of endop...

A rapid and sensitive method for determining aesculin of Cortex fraxini in rat was developed using high-performance liquid chromatography (HPLC) quadrupole time-of-flight (QTOF) tandem mass (MS/MS). Rat plasma was pretreated by fourfold methanol to remove plasma proteins. Chromatographic separation was performed on a reverse phase column. A tandem mass spectrometric detection with an electrospr...

The species diversity of culturable endophytic fungi was studied in the leaves and twigs symptomatic asymptomatic Fraxinus excelsior trees. Endophytic mycobiota dominated by Ascomycota species, with Pleosporales (44.17%) Diaporthales (23.79%) endophytes being most frequently observed tree samples. number isolates richness varied depending on sampling date (May October) tissue location. Of 54 id...

Two Phyllactinia species have been associated with powdery mildew on leaves of ash trees (Fraxinus) in Eurasia, fraxinicola U. Braun & H.D. Shin from Southeast Asia and fraxini (DC.) Fuss Europe. Non-native are planted urban greeneries both Europe Asia, but so far, the two not reported same area. Our molecular analysis European material consisting 55 specimens 15 countries confirmed absence...

Cladosporium chlorocephalum (= C. paeoniae) is a common, widespread leaf-spotting hyphomycete of peony (Paeonia spp.), characterised by having dimorphic conidiophores. During the season, one stage of this fungus causes distinct, necrotic leaf-blotch symptoms on living leaves of Paeonia spp. In late autumn, winter or after overwintering, a second morphologically distinct conidiophore type occurs...
