شناسایی ریخت‌شناختی و مولکولی قارچ‌های اندوفیت جدا شده از درختان فندق جنگل فندقلوی اردبیل

Endophytic fungi are diverse polyphyletic groups of microorganisms and can grow asymptomatically in various healthy tissues of living plants, including stems, leaves, or roots. Endophytic fungi are now considered a treasure trove of unknown biodiversity, which are able to produce a rich variety of bioactive substances and can produce compounds that are similar to the medicinal activities identified from plants. During the last decade, there has been an increase in the number of recording for endophytic fungi with new molecular secondary metabolites that play a key role in the pharmaceutical, phytoremediation and biomedical industries. Since the available information about the diversity of hazelnut endophytic fungi is limited, the present research is conducted in order to identify the endophytic fungi isolated from healthy fruit tissues, including nut, wood shell, involucre, leaf, stem, and root, of Fandoghlou forest in Ardabil. Representatives of each group were then identified by sequencing the ITS nrDNA (ITS1-5.8S-ITS2) region. In this study, 16 fungal genera and 21 species were identifiedincluding Acremonium sclerotigenum, Alternaria sp. ,Biscogniauxia sp., Chaetomium sp., Clonostachys solani, Colletotrichum sp., Curvularia chonburiensis, Diaporthe eres, Drechslera avenae, Epicoccum sp. , Hypoxylon fuscum, H. investiens, Nigrospora camellae-sinensis, N. Vesicularifera, N. Oryzae, Nothophoma quercina, putaminum Paraboeremia, Trichocladium solani and Xylaria longipes. The species Clonostachys solani, Curvularia chonburiensis, Nigrospora camellae-sinensis, N. vesicularifera, Paraboeremia putaminum, Trichocladium solani, Drechslera avenae are new for the mycobiota of Iran.
