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

ABSTRACT:

Introduction

Fusarium solani is a widespread plant pathogen known to damage numerous crops, including causing severe root rot in Panax ginseng. In this study, we identified a novel ourmia-like mycovirus in F. solani, named "Fusarium solani ourmia-like virus 1" (FsoOLV1). We demonstrated that FsoOLV1 confers hypovirulence in its host F. solani and three other ginseng root rot pathogens, F. oxysporum, F. proliferatum, and F. verticillioides. Additionally, we verified its horizontal and vertical transmission capabilities.

Methods

FsoOLV1 was discovered in F. solani strain SJH 2-4 using high-throughput sequencing. The genome sequence of FsoOLV1 was obtained through RT-PCR and RACE. Virus elimination was conducted to
