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.

Natural Occurrence of Fungi and Associated Mycotoxins in Small-Grain Cereals from The Urals and West Siberia Regions of Russia.

fungi dominate the grain microbiota in many regions of the world; therefore, the detection of species that are able to produce mycotoxins has received much attention. A total of 178 grain samples of wheat, barley and oat obtained from the Urals and West Siberia regions of Russia in 2017-2019 were included in the study. Grain contamination with fungi belonging to sections and was analysed using qPCR with specific primers.

Diversity of Physiological and Biochemical Characters of Microdochium Fungi.

The biological characterization of Microdochium majus, M. nivale, and M. seminicola strains with wide geographical origins showed the diversity of their pathogenic properties and metabolite compounds, allowing them to exist in their habitats.

Evidence of Fungi Associated with Cereal Grains in Russia.

In total, 46 strains from five different geographic regions of Russia were explored with respect to genetic diversity, morphology, and secondary metabolites. Based on the results of PCR, 59% and 28% of the strains were identified as and , respectively. As a result of sequencing four genome regions, namely ITS, LSU, BTUB, and RPB2 (2778 bp), five genetically and phenotypically similar strains from Western Siberia were identified as , which, according to our findings, is the prevalent species in this territory.
