Molecular characterization of a novel virga-like virus associated with wheat

Abstract

In this work, we report the detection of a novel single-strand RNA virus from wheat, tentatively named "Triticum aestivum-associated virga-like virus 1" (TaAVLV1). Further characterization revealed that the complete genome of TaAVLV1 is divided into two segments, RNA1 and RNA2, which are 3530 and 3466 nt in length, excluding their respective polyA tails, and each contains only one open reading frame (ORF). The ORF of RNA1 encodes an RNA-dependent RNA polymerase (RdRp), while the ORF of RNA2 encodes a putative protein with methyltransferase and helicase domains. Phylogenetic analysis showed that the RdRp of TaAVLV1 is closely related to those of members of the unclassified virga-like virus group in the family Virgaviridae. Thus, we have identified TaAVLV1 as a putative novel virga-like virus belonging to the family Virgaviridae.
