Identification of a novel hypovirulence-inducing ourmia-like mycovirus from Fusarium solani causing ginseng (Panax ginseng) root rot

This study presents the first hypovirulent ourmia-like virus, FsoOLV1, which reduces the virulence of <i>F. solani</i> and other ginseng root rot pathogens. Our findings suggest that FsoOLV1 could serve as a promising biological agent for controlling ginseng root rot. This research not only expands the diversity of known hypovirulent mycoviruses but also provides a potential candidate for controlling Fusarium diseases in ginseng cultivation.
