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...

Colletotrichum gloeosporioides is a species complex of fungi belonging to the Glomerellaceae family (Ascomycota). It has a global worldwide occurrence and while sometimes described as a plant endophytic commensal, it also often demonstrates pathogenicity on crops and is responsible for anthracnose disease in many cultivated species. Thirty-nine polymorphic microsatellites were isolated and thei...

During our expedition at Lang Biang Biosphere Reserve, samples of DL0023, parasitizing on wasps, were collected, then sent to the biology laboratory, Dalat University, Lam Dong Province, Vietnam, preliminarily morphologically identify name this species as Ophiocordyceps sphecocephala. The method Phenol (pH = 8)/Chloroform was applied isolated DNA. PCR assays and sequencing performed amplify ITS...

The genus Colletotrichum contains many important plant pathogens mainly distributed in tropical areas. Previous studies that utilized morphology or single genes have failed to resolve the phylogenetic relationships among the species. In this study, sequences of β-tubulin, 28S ribosomal DNA, and ITS region from nine species were analyzed separately and combined to establish a fast method to infe...

The Sordariomycetes is one of the largest classes in the Ascomycota, and the majority of its species are characterized by perithecial ascomata and inoperculate unitunicate asci. It includes more than 600 genera with over 3000 species and represents a wide range of ecologies including pathogens and endophytes of plants, animal pathogens and mycoparasites. To test and refine the classification of...

In this study we reassess the taxonomic reference of the previously described holomorphic alkaliphilic fungus Heleococcum alkalinum isolated from soda soils in Russia, Mongolia and Tanzania. We show that it is not an actual member of the genus Heleococcum (order Hypocreales) as stated before and should, therefore, be excluded from it and renamed. Multi-locus gene phylogeny analyses (based on nu...

The characterisation of the causal agents postharvest diseases, as well their pathogenicity in different mango cultivars economic importance Mexico was evaluated. In total, 37 fungi were isolated from diseased (Mangifera indica L.) cvs Ataulfo, Hayden, Manila, Peach, Haden and creole. For morphological characterization, isolates seeded potato dextrose agar media described by 4 variables. molecu...

Background and aims: Colletotrichum graminicola (Glomerellaceae, Glomerellales), the causal agent of maize (Zea mays) anthracnose, as many other fungal pathogens, relies on its battery cell wall degrading enzymes (CWDEs) to make way through walls host, thus production these is considered a virulence factor. Since this disease relatively new in Argentina, little known about capacity CWDEs native...
