Morphological and molecular methods were used to identify the statues of an isolate, EFY-36, a taxolproducing endophytic fungus. Based on the morphology of the fungal colony, the mechanism of spore production and the characteristics of the spores, the isolate is Mucor spp. Furthermore, the analysis of 18S ribosome RNA sequence of the isolate was achieved using PCR technology. The results showed...

(-)-(4S, 8S)-Foedanolide (1a) and (+)-(4R, 8R)-foedanolide (1b), a pair of new spiro-γ-lactone enantiomers, were isolated from the fermentation broth of the plant endophytic fungus Pestalotiopsis foedan by HPLC using a chiral column, achieving over 7% ee. Their structures and absolute configurations were determined on the basis of extensive analysis of NMR spectra combined with computational me...

Chloropestolide A (1), a highly functionalized spiroketal with an unprecedented skeleton derived from a chlorinated bicyclo-[2.2.2]-oct-2-en-5-one ring and a 2,6-dihydroxy-4-methylbenzoic acid unit, has been isolated from the scale-up fermentation extract of Pestalotiopsis fici. The structure of 1 was elucidated by NMR spectroscopy and X-ray crystallography. 1 could be derived from the same Die...

Twenty fungal isolates associated with leaf spots of nutsedge plants (Cyperus spp.) from north of Iran (Guilan, Mazandaran, Zanjan and Golestan Provinces) are examined. According to the results of the morphological studies of grown fungi on culture media, Curvularia clavata, Curvularia lunata var. aeria, Dactylaria higginsii, and Myrothecium brachysporum are new taxa for Iran mycoflora and repo...

In Brazil, one blueberry plant of the cultivar Climax showing symptoms and signs Pestalotiopsis spp. was observed in a commercial orchard. Morphological molecular observations were consistent with those previously reported for trachycarpicola (ex-type trachycarpicola). Koch’s postulates fulfilled. To best our knowledge, this is first report P. trachycarpicola) causing leaf spot Brazil.
