Abstract

Here, we report a novel partitivirus infecting Metarhizium brunneum, which was designated "Metarhizium brunneum partitivirus 2" (MbPV2). The complete genome of MbPV2 consists of two segments, dsRNA1 and dsRNA2, with each dsRNA possessing a single open reading frame (ORF). dsRNA1 (1,775 bp) encodes a conserved RNA-dependent RNA polymerase (RdRp) with the highest sequence similarity to Plasmopara viticola associated partitivirus 1 (PvAPV1), while dsRNA2 (1,568 bp) encodes a coat protein (CP) with the highest sequence similarity to Colletotrichum partitivirus 1 (CtParV1). Phylogenetic analysis based on RdRp sequences showed that MbPV2 is a new member of the genus Gammapartitivirus, family Partitiviridae. This is the first report of a gammapartitivirus that infects the entomopathogenic fungus Metarhizium brunneum.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
