摘要： Wheat plants with yellow stripes on their leaves were collected in the city of Tai'an (Shandong province, China). High-throughput sequencing analysis of the collected plants showed that they were coinfected with wheat leaf yellowing-associated virus (WLYaV) and an unidentified polerovirus. The genome of the unidentified virus, tentatively named "triticum yellow stripe virus" (TriYSV), comprises 5,595 nucleotides and contains seven open reading frames (ORFs), with a typical polerovirus genome structure. Analysis by sequence alignment showed that TriYSV had the highest sequence similarity to wheat yellow dwarf virus (WYDV, a tentative member of the genus Polerovirus), with 87.3% nucleotide sequence identity over the whole genome. Except for P3a and the coat protein (CP), all of the proteins encoded by TriYSV showed < 90% amino acid identity to those of other poleroviruses. Phylogenetic analysis based on RNA-dependent RNA polymerase and CP amino acid sequences and complete genome nucleotide sequences showed that the poleroviruses WYDV, cereal yellow dwarf virus RPS (CYDV-RPS), CYDV-RPV, and barley yellow dwarf virus GPV are the most closely related to TriYSV. Thus, TriYSV is proposed to be a new member of the genus Polerovirus.
