Identification and Pathogenicity of Fungi Associated with Dry Rot of Potato Tubers.

Dry rot of potato tubers is a harmful disease caused by species of the genus. Studies on the composition and features of spp. that cause the disease in Russia are limited.

A novel bipartite negative-stranded RNA mycovirus of the order Bunyavirales isolated from the phytopathogenic fungus Fusarium sibiricum.

A novel negative-stranded RNA mycovirus was isolated from the phytopathogenic fungus Fusarium sibiricum strain AH32. This virus, tentatively named "Fusarium sibiricum coguvirus 1" (FsCV1), has a bipartite genome consisting of two RNA segments (RNA1 and RNA2). The negative-sense RNA1 is 6711 nt in length, encoding the RNA-dependent RNA polymerase (RdRp, p251) in the viral complementary (vc) strand.

, a new cryptic species in the complex associated with sunflower.

A species associated with sunflower based on multilocus genealogy, morphological, physiological, ecological, mating type, and mycotoxin production data is formally described as the newly discovered species . The strains formed a genealogically exclusive lineage within the African clade of the species complex. Comparison of morphological characteristics of strains with those of the closely related strain NRRL 13617 revealed similarities in the main micromorphology of both species: production of numerous one-celled microconidia in false heads and short chains on monophialides and polyphialides and the absence of macroconidia and sporodochia.

Diversity of Fusarium Species and Their Mycotoxins in Cereal Crops from the Asian Territory of Russia.

Up-to-date information on the occurrence of Fusarium fungi and their mycotoxins in the grain of wheat, barley and oats grown in the Urals and West Siberia in 2018‒2019 is presented. Mycological analysis of grain revealed at least 16 species of Fusarium fungi. The F.

Biodiversity of Fungi Inhabiting European Blueberry in North-Western Russia and in Finland.

European blueberry is a common plant in coniferous and mixed forests that grows in Russia, Northern Europe, Asia, United States, and Canada. Among the fungi that cause blueberry diseases, the most harmful are Diaporthe vaccinii and Colletotrichum acutatum. These fungi are included in the consolidated list of quarantine objects of the Eurasian Economic Union and their occurrence and spread in the territory of countries of this Union is subject to strict control.
