We report on the identification and complete genome characterization of three novel partitiviruses naturally infecting the ectomycorrhizal fungus Hebeloma mesophaeum. One of the partitiviruses identified was found to be conspecific with a previously reported partitivirus (LcPV1) described from a saprotrophic fungus Leucocybe candicans. Bio-tracking studies revealed the significant drop in viral loads of LcPV1 in L. candicans but not in H. mesophaeum within four years period, suggesting a potential virus transmission event.
Mycorrhizal fungi host diverse mycoviruses that contribute to our understanding of their diversity and evolution. Here we report on the identification and complete genome characterization of three novel partitiviruses naturally infecting the ectomycorrhizal fungus Hebeloma mesophaeum. During NGS derived viral sequence analyses, we identified a partitivirus that is conspecific with the previously reported partitivirus (LcPV1) described from a saprotrophic fungus Leucocybe candicans. The two distinct fungal specimens inhabited the same vicinity of a campus garden. RdRp sequences encoded by the LcPV1 isolates from both host fungi was found to be identical. Bio-tracking studies revealed that viral loads of LcPV1 drop significantly in L. candicans but not in H. mesophaeum within four years period. The physical proximity of the mycelial networks of both fungal specimens implied the occurrence of a virus transmission event with unknown mechanism. Nature of this virus transmission was dis-cussed in relation to transient interspecific mycelial contact hypothesis.
