PG - 284 LID - 10.1007/s00705-023-05912-5 [doi] AB - In this study, a novel positive single-stranded RNA (+ ssRNA) virus named wheat yellow stripe associated virus (WYSAV) was identified in wheat plants in China. Molecular characterization revealed that the complete genome of WYSAV is divided into two segments, RNA1 and RNA2, which are 6,460 and 4,935 nucleotides (nt) in length, excluding their respective poly(A) tails. RNA1 contains one large opening reading frame (ORF), encoding a replication-associated protein. RNA2 contains six ORFs, encoding a coat protein (CP), a coat protein readthrough domain protein (CP-RTD), triple gene block protein 1 (TGB1), triple gene block protein 2 (TGB2), triple gene block protein 3 (TGB3), and a cysteine-rich protein (CRP). Phylogenetic analysis showed that WYSAV is related to members of the genus Benyvirus in the family Benyviridae. Thus, WYSAV is proposed to be a new member of the genus Benyvirus. Wheat (Triticum aestivum L.) is one of the most important food crops and ranked third in the world in terms of production, only behind rice and maize [1]. During its growth cycle, wheat faces several biotic and abiotic stresses. Wheat soil-borne virus disease is an important disease that is difficult to control and causes severe yield loss in China each year [2]. The main pathogens causing wheat soil-borne virus disease are Chinese wheat mosaic virus (CWMV) and wheat yellow mosaic virus (WYMV), and their transmission vector is Polymyxa graminis [3-5]. Members of the viral family Benyviridae usually have two to five genomic RNA segments and are transmitted by root-infecting vectors belonging to the family "Plasmodiophoridae". Although few members of the family Benyviridae, of which beet necrotic yellow vein virus is the type member, have been identified [6], several recently identified viruses have been found to be phylogenetically related to benyviruses but are not classified as members of the family Benyviridae. These "unclassified benyviruses" include red clover RNA virus 1, Arceuthobium sichuanense virus 3, Dactylorhiza hatagirea beny-like virus, goji berry chlorosis virus [7], Guiyang benyvirus 1, Guiyang benyvirus 2, Mangifera indica latent virus [8], Rhizoctonia solani beny-like virus 1 [9], Sanya benyvirus 1 [10], and Sclerotium rolfsii beny-like virus 1 [11].In this study, we identified a novel + ssRNA virus in symptomatic leaf samples collected from cultivated wheat in the city of Zhumadian, Henan Province, China. We propose to name this virus "wheat yellow stripe associated virus" (WYSAV), and we have deposited its full-length sequence in the GenBank database under the accession numbers OQ547804 (RNA1) and OQ547805 (RNA2).
