Brief Report

Abstract

A novel bisegmented double-stranded RNA virus was identified in the mycoparasitic and opportunistic fungus Hypomyces chrysospermus. The RNA1 genome segment comprises 1866 bp and encodes an RNA-dependent RNA polymerase (RdRp). The RNA2 segment comprises 1822 bp and encodes a capsid protein. Phylogenetic analysis of the RdRp protein indicated that this virus is a new member of genus Alphapartitivirus in the family Partitiviridae. We have designated this mycovirus as “Hypomyces chrysospermus partitivirus 1” (HcPV1). HcPV1 is highly transmissible with aleurioconidia and is present in large amounts within growing mycelium in comparison to the GAPDH reference gene.
