Poly(ADP-ribose) polymerase (PARP) is the key enzyme in polyADP-ribosylation, one of the main post-translational modifications. This enzyme is abundant in eukaryotic organisms. However, information on the PARP structure and its functions in members of the Fungi kingdom is very limited.

Mycotoxin contamination of food and feed is a worldwide problem that needs to be addressed with highly efficient and biologically safe techniques. RNA interference (RNAi) is a natural mechanism playing an important role in different processes in eukaryotes, including the regulation of gene expression, maintenance of genome stability, protection against viruses and others. Recently, RNAi-based techniques have been widely applied for the purposes of food safety and management of plant diseases, including those caused by mycotoxin-producing fungi.

Symmetric molecules exist as distinct nuclear spin isomers (NSIMs). A deeper understanding of their properties, including interconversion of different NSIMs, requires efficient techniques for NSIM enrichment. In this work, selective hydrogenation of acetylene with parahydrogen (p-H) was used to achieve the enrichment of ethylene NSIMs and to study their equilibration processes.

Recent improvements in microbiology and molecular epidemiology were largely stimulated by whole- genome sequencing (WGS), which provides an unprecedented resolution in discriminating highly related genetic backgrounds. WGS is becoming the method of choice in epidemiology of fungal diseases, but its application is still in a pioneer stage, mainly due to the limited number of available genomes. Fungal pathogens often belong to complexes composed of numerous cryptic species.

Zearalenone (ZEN) and deoxynivalenol (DON) are mycotoxins produced by various species of fungi. They contaminate agricultural products and negatively influence human and animal health, thus representing a serious problem of the agricultural industry. Earlier we showed that compactin, a secondary metabolite of , is able to completely suppress the aflatoxin B1 biosynthesis by Using the strain FC-19 able to produce DON and ZEN, we demonstrated that compactin also significantly suppressed both DON (99.
