dahliae capable of infecting plants from 14 plant families, whereas V. The species also differ in host range, with V. dahliae manifests as wilting with or without defoliation on cotton and olive plants. nonalfalfae cause mild and lethal wilting symptoms in hop plants, respectively and infection with defoliating and non-defoliating pathotypes of V. The Verticillium sensu stricto species also differ in pathogenicity: the less virulent and highly virulent fungal isolates of V. tricorpus forming more than one type of resting structure. The three types of resting structures include resting mycelia, microscleorotia, and clamidospores, with the species V. One of the features of Verticillium sensu stricto species is the formation of resting structures, by which the species remain dormant in the soil for long periods, even without a host plant. Hyphae and conidia are mostly haploid, and conidia are produced on long philaides. Verticillium sensu stricto species are soil-borne fungi with hyaline mycelia. The 12 newly identified SSR markers, which were used in simplex PCR reactions or in combination, enabled the accurate identification of all included Verticillium isolates and could potentially be used as biomarkers for rapid and easy species identification. To enable the accurate distinction of the fungi, the SSR and LAMP markers were added to the analyses. dahliae identification proved to be less specific, and it resulted in the positive amplification of Gibellulopsis nigrescens, V. With the PCR marker system proposed by Inderbitzin and coworkers in 2011, we re-classified 88 Verticillium isolates out of the 105 samples that are held in the institute’s bank, which were obtained from different geographic locations in Europe, North America, and Japan, and from different host plants, including alfalfa, cotton, hop, olive, potato, and tomato. ![]() The objective of our study was the re-classification of the fungal species held in the culture collection in the Slovenian Institute of Hop Research and Brewing in accordance with the newly established taxonomy. In 2011, a new taxonomic classification, proposed by Inderbitzin and coworkers (2011), re-defined the genus as Verticillium sensu stricto. The genus Verticillium is a group of ascomycete fungi that includes several pathogenic plant species.
