Sixteen isolates of Colletotrichum were collected from leaves with anthracnose symptoms or leaf spots of twelve wild, cultivated and ornamental plant species from the Guilan, Mazandaran, and Golestan provinces in Northern Iran. Five different species, including C. aenigma, C. gigasporum, C. godetiae, C. karstii, and C. musae were identified based on the DNA sequence data (TUB2, GS, GAPDH). Four...
background and purpose: trichosporon is a genus of anamorphic basidiomycetous yeast which is widely distributed in nature and is found in tropical and temperate areas. the aim of this work was to study the isolation, identification and molecular analysis of trichosporon species in soil. materials and methods: in order to isolate and identify trichosporon species in soil, 30 samples were collect...
the genus phaeoacremonium is associated with decline disease of woody plants and with human infections. members of this genus have broad host range and wide geographical distribution. during 2010, ten isolates of phaeoacremonium were recovered from vascular tissues of persimmon (diospyros kaki) trees, showing decline symptoms in shiraz city. anamorphic characteristics such as, conidiophore morp...
abstract: postmethod is a newly developed pedagogy which as an alternative to method rejects the notion of good or bad methods and the concept of best method that can be generalized and appropriate for all contexts. instead, it treats each context as unique and one of a kind which cant be compared with other cases. this study is a postmethod-oriented one which investigates whether and how far t...
Background and Purpose: Lipophilic yeast of the genus Malassezia are members of normal human cutaneous micro flora which are also associated with several skin diseases. It is strongly suspected that Malassezia species are responsible for pityriasis versicolor (PV), and seborrhoeic dermatitis (SD). Considering various sensitivities among Malassezia species to antifungal, accurate species identif...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...

Endophytic fungi constitute a remarkable multifarious group of microorganisms live within plants tissues without causing any obvious negative effect. Endophytic fungi have been found in every plant species examined to date. During an investigation on endophytic fungi, 123 fungal isolates were obtained from healthy twigs and leaves of cherry (Prunus avium) and sour cherry (P. cerasus) trees in I...
