Dictionary of the Fungi

Abstract: For each genus, the authority, the date of publication, status, systematic position, number of accepted species, distribution, and key references are given. Diagnoses of families and details of orders and higher categories are included for all groups of fungi. In addition, there are biographic notes, information on well-known metabolites and mycotoxins, and concise accounts of almost all pure and applied aspects of the subject (including citations of important literature).

Preserving accuracy in GenBank

Abstract: GenBank, the public repository for nucleotide and protein sequences, is a critical resource for molecular biology, evolutionary biology, and ecology. While some attention has been drawn to sequence errors ([1][1]), common annotation errors also reduce the value of this database. In fact, for

The typification of Colletotrichum gloeosporioides

Abstract: The anamorphic species Colletotrichum gloeosporioides has never been adequately typified according to modern nomenclatural practice, resulting in uncertainty as to application of the named A lectotype specimen is therefore designated to preserve current usage, with an epitype also chosen as eligible lectotype material is not preserved in a living state. The epitype strain is described and characterized using morphological and molecular methods. There are three distinct rDNA ITS sequences of the epitype strain in GENBANK, so it has been re-sequenced to confirm the true base-pair structure.

Domain II Hairpin Structure in ITS1 Sequences as an Aid in Differentiating Recently Evolved Animal and Plant Pathogenic Fungi

Abstract: The hypothesis that ITS structural features can be used to define fungal groups, where sequence analysis is unsatisfactory, was examined in plant and animal pathogenic fungi. Structural models of ITS1 regions were predicted for presumed closely related species in Colletotrichum and Trichophyton anamorphs of Arthroderma species. Structural alignment of models and comparison with ITS sequence analysis identified a variable region in a conserved hairpin formed from a common inverted repeat. Thirteen different hairpin structure models were obtained for Colletotrichum species and five different models were obtained for Trichophyton species. The different structure types could be matched to individual species and species complexes as defined by ITS sequence analysis.
