Zinniol analogues from the endophytic fungus Arcopilus sp. YUD20001 associated with Gastrodia elata

<i>Arcopilus aureus</i>: a valuable endophytic associate of hazelnut

“…In this region, an isolate from another orchid (Gastrodia elata) was identified as Arcopilus sp. (Duan et al, 2022); however, a blast in GenBank of its ITS sequence shows 100% homology with 18 isolates of A. aureus, besides an isolate of Arcopilus globulus. is latter match may have raised doubts in the authors about the correctness of the classification, which were dispelled considering that this species is now designated as a synonym of A. aureus (Wang et al, 2022).…”

“…Better known as pigments and for possible application as food colorants are compounds belonging to the polyketide class of azaphilones (Pimenta et al, 2021), which were discovered as products of an endophytic strain isolated in Morocco; particularly, isochromophilone IV and VII, sclerotioramin and sclerotiorin were extracted from cultures of this strain along with the tricyclic compound SB236050 and the new resorcinol derivative chaetorcinol (Kabbaj et al, 2015). Extracted from an endophytic strain from G. elata along with the biosynthetic analogs maristachone B, 8-zinniol methyl ether, and the novel arcopiniols A-C (Duan et al, 2022), zinniol is another product which was first characterized as a phytotoxin from several Alternaria and Phoma species (Cotty & Misaghi, 1984;Sugawara & Strobel, 1986); however, this biological effect has been questioned aer more recent experimental assessments (Qui et al, 2010).…”

Two Decarestrictine Analogs from the Soil‐Derived Fungus Penicillium sp. YUD18003 Associated with Gastrodia elata

“…[11] During the study of fungal secondary metabolites, we have isolated many natural products with different structures and biological activities. [12][13][14][15] Recently, a fungus Penicillium sp. YUD18003 was isolated from rhizospheric soil associated with Gastrodia elata.…”
