بیماری خال سیاه سیب زمینی توسط colletotrichum coccodes ایجاد می شود و در اکثر مناطق کشت سیب زمینی ایران پراکنده است. عامل بیماری یکی از عوامل مهم کاهش عملکرد در مزرعه است و باعث پوسیدگی غده ها و افت وزن محصول در انبار می شود. وضعیت تنوع ژنتیکی و توان بیماری زایی این قارچ در ایران مشخص نبود. برای این منظور از مناطق عمده سیب زمینی کاری استان های اردبیل ، اصفهان و همدان اقدام به نمونه برداری از گ...
Oleaginous fungi are of special interest among microorganisms for the production of lipid feedstocks as they can be cultured on a variety of substrates, particularly waste lingocellulosic materials, and few fungal strains are reported to accumulate inherently higher neutral lipid than bacteria or microalgae. Previously, we have characterized an endophytic filamentous fungus Colletotrichum sp. D...
A novel double-stranded RNA (dsRNA) mycovirus, consisting of three dsRNA genome segments and possibly belonging to the family Chrysoviridae, was isolated from the filamentous phytopathogenic fungus Colletotrichum gloeosporioides and designated as Colletotrichum gloeosprioides chrysovirus 1 (CgCV1). The three dsRNAs of the CgCV1 genome with lengths of 3397, 2869, and 2630 bp (dsRNAs1-3) were fou...
در اردیبهشت سال 1390، علایم آنتراکنوز روی ساقههای بامبو (dracaena sanderiana) زینتی وارداتی در شهرستان گرگان مشاهده شد. قارچ عامل بیماری براساس کلید فار و همکاران(farr et al. 2006) تحت عنوان colletotrichum dracaenophilum d.f. farr & m.e. palm شناسایی شد.
Apple fruit rot disease is one of the major apple diseases in Indonesia. It has been caused by several species pathogenic within genus Colletotrichum. This research aims to identify pathogen causing Pujon, East Java. Suspected fungal isolates were identified based on morphological (macroscopic and microscopic) molecular characteristics. Based observation, five as Colletotrichum spp. These have ...
Appressorium formation in germinating Colletotrichum gloeosporioides is induced by the surface wax of its host. One of the genes expressed uniquely in C. gloeosporioides during appressorium formation induced by the host signal has been designated cap20, and this gene and its cDNA were cloned and sequenced. Nucleotide sequences of both revealed an open reading frame that could encode a 183-amino...
Olive anthracnose, caused by Colletotrichum, is an important disease in olive-growing regions, with the most destructive symptoms being fruit rot and blossom blight. Susceptibility of to Colletotrichum increases maturity, but differences between cultivars species have been reported, still information on flower susceptibility during development scarce. The olive Arbequina, Coratina, Frantoio Pic...
