摘要： Here, we report a novel wheat-infecting marafivirus, tentatively named "Triticum aestivum marafivirus" (TaMRV). The full-length genome sequence of TaMRV comprises 6,437 nucleotides, excluding the poly(A) tail. Pairwise sequence comparisons and phylogenetic analysis revealed that TaMRV may represent a novel species within the genus Marafivirus in the family Tymoviridae. We also observed a mass of isometric particles with a diameter of about 30 nm in ultrathin sections of infected wheat leaf tissue. In addition, the leafhopper Psammotettix alienus was identified as a vector for this virus. This is the first report of the occurrence of a wheat-infecting marafivirus.
