A New Eudesmane Sesquiterpene from Nigrospora oryzae, an Endophytic Fungus of Aquilaria sinensis

چکیده
A new eudesmane-type sesquiterpene, 11-hydroxycapitulatin B (1), along with a known related sesquiterpene, capitulatin B (2), was isolated from the endophytic fungus Nigrospora oryzae A8 from Aquilaria sinensis, the only plant resource for agarwood production in China. This research demonstrates that the endophytic fungi from A. sinensis might play a role in the formation of agarwood.

Nigrospora oryzae an endophytic fungus isolated from the leaf of a climber Pterolobium hexapetalum (Roth.) Sant. and Wagh. produced bioactive compound which are active against human pathogens. The organic extract (ethanol) of the endophyte Nigrospora oryzae was separated using HPLC and tested for biological activities. The ethanol extract was tested for antibacterial and anti fungal activity us...
متن کاملJasmonic acid is a crucial signal transducer in heat shock induced sesquiterpene formation in Aquilaria sinensis
Agarwood, a highly valuable resinous and fragrant heartwood of Aquilaria plants, is widely used in traditional medicines, incense and perfume. Only when Aquilaria trees are wounded by external stimuli do they form agarwood sesquiterpene defensive compounds. Therefore, understanding the signaling pathway of wound-induced agarwood formation is important. Jasmonic acid (JA) is a well-characterized...

Five new 2(5H)-furanone-type derivatives, pestalafuranones F-J (compounds 3-7), together with two known compounds, pestalafuranones A (1) and B (2), were isolated from the ethyl acetate extract from the fermentation broth of the endophytic fungus Nigrospora sp. BM-2 in a hypersaline medium. The structures of these metabolites were elucidated by EIMS, HREIMS and NMR spectroscopic data. Compounds...

In the present study, five species of Cladosporium including C. perangustum, C. basi-inflatum, C. cladosporioides, C. herbarum and C. subtilissimum,and three species assigned to other fungal genera including Truncatella angustata, Alternaria atra and Nigrospora oryzea are reported as endophytic fungi of common yew (Taxus baccata L.), native to Iran. Out of these, C. perangustum, C. basi-inflat...
متن کاملDifferential Communications between Fungi and Host Plants Revealed by Secretome Analysis of Phylogenetically Related Endophytic and Pathogenic Fungi
During infection, both phytopathogenic and endophytic fungi form intimate contact with living plant cells, and need to resist or disable host defences and modify host metabolism to adapt to their host. Fungi can achieve these changes by secreting proteins and enzymes. A comprehensive comparison of the secretomes of both endophytic and pathogenic fungi can improve our understanding of the intera...
