In this paper we give an account of species in the genus Diaporthe. Since morphological characters are inadequate to define species in this genus, DNA sequence data are essential to differentiate them. We therefore focus this paper on the 171 species for which ex-type/exepitype/ex-isotype/ex-neotype isolates and corresponding molecular data are available and these species are listed alphabetically. Sexual or asexual morph are noted under each species, detailed descriptions of type materials, host records and geographic distribution are provided. Available DNA sequence data from ex-type cultures are listed in Table 1. Phylogenetic relationships of the species are given in a multi-locus phylogenetic tree based on combined ITS, tef1-α, β-tubulin and CAL sequences.

“…For example, Diaporthe phaseolorum var. caulivora, which was isolated from the soybean in this study, is an important pathogen in North and South America (Kulik, 1989;Hartman et al, 1999;Costamilan et al, 2008), but has never been found in Japan. Such infested grains imply risks; not only in bean sprout production but also in crop protection of the importing countries.…”

Fungi Isolated from Spoiled Bean Sprouts in Japan

The morphology of 18 and seven species of fungi isolated from spoiled bean sprouts of Vigna spp. and soybean in Japan were respectively described, and DNA barcode markers of most isolates were sequenced to confirm the morphological identification. Fifteen and five species were isolated for the first time from Vigna spp. and soybean sprouts, including their ingredient grains, respectively. Globisporangium ultimum var. ultimum was newly recorded from the mung bean and most isolated fungi seemed to originate from the grains. Approximately 70% of isolates are recognized as plant pathogens and at least 14 species are known to be seed-borne. Inoculation experiments with representative strains of each species are needed to estimate the risks to bean sprout production and crop protection. Some strains of Fusarium graminearum isolated from the soybean were already reported as producing high concentrations of deoxynivalenol. Aspergillus flavus, which was found in mung bean sprouts, is a well-known aflatoxin producer. The ingredient grains should be imported after complete sterilization to avoid hazards; not only to bean sprout production but to human health. The effects of previously used sterilization techniques should be re-examined with the strains of various fungi isolated in this study to make them more practical.

“…Instead, programmed cell death or apoptosis occurs in the mycelial cells that are in contact with an isolate representing different vegetative compatible groups (Leslie, 1993). Previous vegetative compatibility assays have been performed for the SSC pathogens, but involving solely two Brazilian isolates (Costamilan et al, 2008).…”

Specific boundaries between the causal agents of the soybean stem canker

Pathogens within the Diaporthe complex cause seed decay, stem blight and stem canker on soybean, representing a serious threat for this crop species. We herein utilize worldwide sequence data retrieved from Genbank in order to assess the species boundaries between the soybean stem canker causal agents, and define whether or not they should be regarded as members of the same biological species. These studies were complemented with compatibility tests, in order to validate our findings from a biological standpoint. Species delimitation assays supported the occurrence of a speciation event between D. caulivora and D. phaseolourm var. meridionalis. A speciation hypothesis between D. aspalathi and D. phaseolourm var. meridionalis was also supported, based on three reciprocally monophyletic substitutions at locus EF1-α. Compatibility tests further validated species delimitation assays indicating that D. caulivora has developed barriers to gene exchange with D. phaseolorum var. meridionalis. Clarification of the specific boundaries of the SSC pathogens and related entities will be an important asset to future research in soybean pathology, epidemiology and breeding.
