AB  - Seed decay is one of the most important diseases of soybean (Glycine max (L.) Merr.) that has a negative impact on the market grade of soybeans. The disease is mainly caused by Diaporthe longicolla, along with other Diaporthe species. Screening of soybean seeds health status in Vojvodina Province, Serbia, showed cultural and morphological variability among isolates identified as D. longicolla. With the use of DNA sequences of internal transcribed spacer (ITS1-5.8S-ITS2) region and partial translation elongation factor 1-alpha (EF1-α), the new species was determined. BLAST analysis showed 100% identity with D. pseudolongicolla (syn. D. novem) that was described in this study and its taxonomic revision is discussed. Pathogenicity trial showed that both species, D. longicolla and D. pseudolongicolla, are highly pathogenic on soybean stem and seed, causing 100% of stem wilting and more than 82% of seed decay.
AB  - Trulež semena je jedna od najvažnijih bolesti soje (Glycine max (L.) Merr.), koja negativno utiče na vrednost soje na tržištu. Najčešće je uzrokuje Diaporthe longicolla, zajedno sa drugim Diaporthe vrstama. Pregledom zdravstvenog stanja semena soje u Vojvodini (Srbija) uočena je morfološka varijabilnost između izolata identifikovanih kao D. longicolla. Upotrebom sekvenci DNK iz ITS regiona (ITS1-5.8S-ITS2) i elongacionog faktora 1-alfa (EF1-α) potvrđeno je prisustvo nove vrste na semenu soje. BLAST analizom je dokazana identičnost od 100% sa D. pseudolongicolla (sin. D. novem) koja je opisana u ovom radu i čija taksonomska revizija se razmatra. Ispitivanja patogenosti su pokazala da su obe vrste, D. longicolla i D. pseudolongicolla, visoko patogene na stablu i semenu soje uzrokujući 100% uvenuće biljaka kao i trulež više od 82% semena.

AB  - Soybean and field pea are the most important legumes worldwide. However, diseases are a strong limitation to obtaining stable yields, among which Ascochyta blight complex is one of the most significant and widespread pathogens. Three causal agents of pea diseases have been described: Peyronellaea pinodes, the most common and most damaging causal agent of blight; P. pinodella, the causal agent of foot rot; and Ascochyta pisi, causal agent of blight and pod spot. Only A. sojaecola is reported as causal agent of leaf spot on soybean. Taxonomy of Peyronellaea and Ascochyta species was the subject of many studies for a long time. Initial identification was based on morphological characteristics, which is difficult because morphological features often vary and "overlap", making it impossible to establish the appropriate taxonomic rank.

AB  - P. longicolla is primarily known as a soybean seedborne pathogen but it can be isolated from all parts of the plant. Atypical symptoms have been frequently noted on the basal parts of soybean stems of mature plants: slightly sunken lesions with irregular shapes and sizes, bordered by a thin black margin with diffusely distributed pycnidia with α and β conidia. Initially, it was believed that the causal agent was the fungus P. sojae, however morphological characteristics of the isolates suggested that the causal agent was not P. sojae. This study was an attempt to prove that, under certain conditions, P. longicolla produces masses of β conidia. Beta conidia were observed for quite some time in the field, but they were believed to belong to P. sojae, which typically forms this type of conidia. However, after isolation from infected plant parts, the fungus formed colonies and reproductive organs which were identical to the morphological characteristics of P. longicolla described by Hobbs et al. (1985). In other words, we found evidence that the isolated fungus was P. longicolla.

AB  - Although Phomopsis longicolla is primarily known as a seedborne pathogen, it can be isolated from all parts of the plant. The disease lesions observed on the basal parts of soybean stems were slightly sunken with irregular shapes and sizes, bordered by a thin black margin. Within the lesions themselves, large and diffusely distributed pycnidia with and conidia, typical of the genus Phomopsis, were observed. The percentages of the two types of conidia varied considerably, but conidia were predominant in most of the pycnidia. The presence of these reproductive organs indicated that the symptoms could have been caused by Phomopsis sojae. However, after isolation on a nutritive medium, all cultural and morphological characteristics clearly indicated that the isolated fungus was P. longicolla, whose identification was subsequently confirmed by sequencing three genomic regions. Monosporic isolates, with different ratios of and conidia, exhibited a high level of pathogenicity on soybean, after artificial inoculation. Both types of conidia were observed on the stems of the inoculated soybean plants. Beta conidia also formed quickly on medium made of soybean seeds and mature stems after exposure to low temperatures (-10 degrees C). This study suggests that P.longicolla is capable of a massive production of conidia, not only in old fungal cultures as it had until now been believed, but also in infected soybean plants in the field.

abstract = "Although Phomopsis longicolla is primarily known as a seedborne pathogen, it can be isolated from all parts of the plant. The disease lesions observed on the basal parts of soybean stems were slightly sunken with irregular shapes and sizes, bordered by a thin black margin. Within the lesions themselves, large and diffusely distributed pycnidia with and conidia, typical of the genus Phomopsis, were observed. The percentages of the two types of conidia varied considerably, but conidia were predominant in most of the pycnidia. The presence of these reproductive organs indicated that the symptoms could have been caused by Phomopsis sojae. However, after isolation on a nutritive medium, all cultural and morphological characteristics clearly indicated that the isolated fungus was P. longicolla, whose identification was subsequently confirmed by sequencing three genomic regions. Monosporic isolates, with different ratios of and conidia, exhibited a high level of pathogenicity on soybean, after artificial inoculation. Both types of conidia were observed on the stems of the inoculated soybean plants. Beta conidia also formed quickly on medium made of soybean seeds and mature stems after exposure to low temperatures (-10 degrees C). This study suggests that P.longicolla is capable of a massive production of conidia, not only in old fungal cultures as it had until now been believed, but also in infected soybean plants in the field.",
