dc.description.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. | en |
