Abstract

Phytopathogenic fungal species of the Diaporthe/Phomopsis complex (DPC) are associated with three highly destructive diseases on soybean: seed decay, pod and stem blight, and stem canker. They are responsible for poor seed quality and significant yield reduction in most soybean producing areas. Precise identification and classification of DPC species is important in understanding the epidemiology of disease and to develop effective control measures. Although cultural and morphological characteristics of DPC associated pathogens have been described, establishing a more accurate taxonomic framework seems necessary for a revaluation of the taxonomy and phylogeny of DPC species. In this study, we focused on morphological and molecular analyses of species from DPC-damaged European soybean seeds obtained from several locations throughout Europe. Colony characteristics, conidia dimensions, existence of α- and β-conidia, and formation of perithecia were evaluated in order to assign the isolates to a species morphologically. Phylogenetic relationships were determined based on sequences from beta-tubulin (TUB), translation elongation factor 1-alpha (TEF1) and nuclear ribosomal DNA internal transcribed spacers (ITS). Combining the results from morphological and molecular tools placed the 32 DPC isolates into the four species D. longicolla, D. caulivora, D. eres, and D. novem, which are well-known soybean pathogens. Current species descriptions of DPC are still unclear and sometimes overlapping. In this manuscript we present updated taxonomic data.
