RNA interference core components identified and characterised in Verticillium nonalfalfae, a vascular wilt pathogenic plant fungi of hops.

ABSTRACT: The conserved RNA interference mechanism (RNAi) in the fungal kingdom has become a focus of intense scientific investigation. The three catalytic core components, Dicer-like (DCL), Argonaute (AGO), and RNA-dependent RNA polymerase (RdRP), and their associated small interfering RNA molecules (siRNAs) have been identified and characterised in several fungal species. Recent studies have proposed that RNAi is a major contributor to the virulence of fungal pathogens as a result of so-called trans-kingdom RNA silencing. In the present study, we report on the existence of three core RNAi proteins in the pathogenic plant fungus Verticillium nonalfalfae, which is a soilborne plant pathogen that causes severe wilting disease in hops (Humulus lupulus L.). Two DCL proteins, two AGO proteins, and two R
