Although only recently described, Colletotrichum boninense is well established in literature as an anthracnose pathogen or endophyte of a diverse range host plants worldwide. It especially prominent on members Amaryllidaceae, Orchidaceae, Proteaceae and Solanaceae. Reports from preliminary studies using ITS sequence data indicated that C. represents species complex. A multilocus molecular phylogenetic analysis (ITS, ACT, TUB2, CHS-1, GAPDH, HIS3, CAL) 86 strains previously identified other...
The Amsterdam Declaration on Fungal Nomenclature was agreed at an international symposium convened in 19-20 April 2011 under the auspices of International Commission Taxonomy Fungi (ICTF). purpose to address issue whether or how current system naming pleomorphic fungi should be maintained changed now that molecular data are routinely available. is urgent as mycologists currently follow different practices, and no consensus achieved by a Special Committee appointed 2005 Botanical Congress...

Many fungi are pathogenic on plants and cause significant damage in agriculture forestry. They also part of the natural ecosystem may play a role regulating plant numbers/density. Morphological identification analysis fungi, while important, is often hampered by scarcity discriminatory taxonomic characters endophytic or inconspicuous nature these fungi. Molecular (DNA sequence) data for have emerged as key information diagnostic classification studies, although non-standard laboratory...

This species frequently confused a taxon generally referred as G. mangiferae, presumed teleomorph P. capitalensis, which non-pathogenic endophyte, commonly isolated from citrus leaves fruits wide range other...
Oomycetes are a diverse group of eukaryotes in terrestrial, limnic and marine habitats worldwide include several devastating plant pathogens, for example Phytophthora infestans (potato late blight). The cytochrome c oxidase subunit 2 gene (cox2) has been widely used identification, taxonomy phylogeny various oomycete groups. However, recently the cox1 was proposed as DNA barcode marker instead, together with ITS rDNA. locus some studies Pythium Phytophthora, but rarely other oomycetes,...
