Endophytes provide mutual benefits and produce various biologically active secondary metabolites in plants. Our study was designed to isolate identify fungal endophytes from fresh leaf bark of Tinospora cordifolia, coupled with their bioactivity preliminary chemical screening. Six endophytic fungi were isolated using surface sterilization technique. The identified by microscopic molecular chara...

Community science-generated biodiversity data can provide essential information for understanding species distributions, behaviors and conservation statuses. However, their utility be limited due to high uncertainty variability in quality, especially small taxonomically difficult organisms like fungi insects. One important set of community-generated that are increasingly used by scientists Rese...

This experiment was aimed at establishing, for the first time, the survival capability of lichens exposed to space conditions. In particular, the damaging effect of various wavelengths of extraterrestrial solar UV radiation was studied. The lichens used were the bipolar species Rhizocarpon geographicum and Xanthoria elegans, which were collected above 2000 m in the mountains of central Spain an...

The effectiveness of lichens in degrading their rock substrates, leading to the first stages in the formation of soil, has long been discussed and opinions have varied widely (Jones, 1988; Syers & lskandar, 1973). Nevertheless, it is generally recognized that lichen encrusted rocks provide an ideal environment for studying the biological weathering of minerals since, unlike the situation in soi...

A recent taxonomic revision of Microascaceae with an emphasis on synnematous fungi enabled re-identification of previously isolated indoor strains of Cephalotrichum. All available Cephalotrichum strains from the culture collection of the Westerdijk Institute were studied, 20 originating from the built environment. Phylogenetic relationships were inferred from DNA sequence data from the internal...

شبه قارچ پی تیوم یکی از بیمارگرهای مهم بوده که در سراسر دنیا پراکنده است و با توجه به این که در بخش کشاورزی عامل بیماری های مختلفی در اغلب گیاهان زراعی، باغی، زینتی، جنگلی می باشد و هر سال خسارات عمده ای به این بخش وارد می کند، از جنبه های مختلف، به ویژه از نظر طبقه بندی و شناسایی گونه ها، بوم شناسی، زیست شناسی و بیماری زایی مورد توجه بیماری شناسان گیاهی دنیا قرار گرفته است. استان همدان به دلیل...

The genus Tuber ( Tuberaceae , Pezizales ) is an important fungal group of Ascomycota both economically and ecologically. However, the species diversity, phylogenetic relationships, geographic distribution in China remains poorly understood, primarily because descriptions many new relied heavily on morphological features with molecular data either not sought or ignored. misapplication European ...
