Abstract
Phytopathogenic species of Diaporthe are associated with the serious diseases including seed decay, pod and stem blight and stem canker of soybean leading to considerable loss of crop production worldwide. Accurate identification of the species that cause these diseases has been difficult due to the lack of a recent comprehensive phylogenetic and taxonomic revision. In this study, we revised the phylogenetic placement of the soybean seed decay and pod and stem blight pathogens, D. longicolla and D. sojae, as well as Diaporthe phaseolorum and closely related taxa. Species boundaries of the Diaporthe sojae species complex were determined based on combined phylogenetic analysis of five gene regions: partial sequences of calmodulin (CAL), beta-tubulin (TUB), histone-3 (HIS), translation elongation factor 1-α (EF1-α), and the nuclear ribosomal internal transcribed spacers (ITS). A multi-gene phylogeny inferred for available ex-type isolates of Diaporthe was used to determine the relative phylogenetic position of the D. sojae species complex with respect to other known Diaporthe species. Phylogenetic analyses revealed that this species complex is comprised of soybean pathogens as well as species associated with hosts in Apiaceae, Asteraceae, Convolvulaceae, Cucurbitaceae, Fabaceae and Solanaceae, including mostly vegetables and other herbaceous field crops and weeds. Diaporthe arctii, D. batatas, D. phaseolorum and D. sojae are epitypified and synonyms are clarified. The seed decay pathogen Diaporthe longicolla was determined to be distinct from D. sojae. Diaporthe phaseolorum associated with stem and leaf blight of Lima bean was not found to be associated with soybean in this study. In addition, Diaporthe cucurbitae, the pathogen causing black rot of cucumbers, was distinguished from D. melonis causing soft rot of cantaloupe. The taxon D. phaseolorum var. brevistylospora, causing concave rot of melon in Japan, is conspecific with D. sojae. A new species, D. ueckerae, associated with Cucumis melo from Oklahoma, is introduced with full description and illustrations.
