In order to investigate the diversity of endophytes, fungal endophytes in Panax ginseng Meyer cultivated in Korea were isolated and identified using internal transcribed spacer (ITS) sequences of ribosomal DNA. Three cultivars of 3-year-old ginseng roots (Chunpoong, Yunpoong, and Gumpoong) were used to isolate fungal endophytes. Surface sterilized ginseng roots were placed on potato dextrose ag...

As part of our ongoing investigation of filamentous fungi for anticancer leads, an active fungal extract was identified from the Mycosynthetix library (MSX 63935; related to Phoma sp.). The initial extract exhibited cytotoxic activity against the H460 (human non-small cell lung carcinoma) and SF268 (human astrocytoma) cell lines and was selected for further study. Bioactivity-directed fractiona...

Endophytes are being considered for use in biological control, and the enzymes they secrete might facilitate their initial colonization of internal plant tissues and direct interactions with microbial pathogens. Microbial proteases are also biotechnologically important products employed in bioremediation processes, cosmetics, and the pharmaceutical, photographic and food industries. In the pres...

Evaluation of Rhizoctonia zeae as a potential biological control option for fungal root diseases of sugar beet" (2015). Abstract Several common root diseases routinely damage sugar beet in Nebraska and other production areas of the Central High Plains, and it is becoming more common to find fields infested simultaneously with multiple pathogens. Owing to the shortage of available fungicides for...

The assembly of fungal communities on stone materials is mainly influenced by the differential bioreceptivity of such materials and environmental conditions. However, little is known about the role of fungal interactions in the colonization and establishment of fungal species. We analyzed the effects of intra- and interspecific interactions between 11 species of fungi in oligotrophic and copiot...

گردوی ایرانی (persian walnut) با نام علمی juglans regiaجزو گونه های مهم تجاری و با سطح زیر کشت وسیع می باشد. به منظور مطالعه میکوفلور مرتبط با لکه برگی، شانکر، سرشاخه میری و پوسیدگی میوه گردو طی ماه های بهار، تابستان و پاییز سال 1390 از مناطق مختلف گردوکاری استان کردستان نمونه برداری به عمل آمد. نمونه ها در پاکت های جداگانه با ذکر محل و تاریخ به آزمایشگاه منتقل شدند. جداسازی و خالص سازی جدایه ه...

Endophytes are considered as an important source of bioactive natural products because thesemicroorganisms are able to occupy unique biological niches and grow in non-ordinaryenvironments. Therefore, endophytic fungi of medicinal plants can be developed for medicinalapplications. On the other hand, medicinal properties of plant can be ascribed to its endophyticfungi. Thymus sp. is widely used a...

Phoma black stem and leaf spot disease (Phoma medicaginis) not only destroys annual Medicago spp. forage seed yield but also reduces herbage quality by consequent phytoestrogen production that ovulation of grazing animals. Two controlled environment studies evaluated the effects plant developmental stage in rugosa ‘Paraponto’ M. scutellata ‘Sava’ different inoculum concentrations P. medicaginis...
