Complete genome sequence of zoysia mosaic virus, a novel member of the genus Poacevirus.

Here, we report the detection and characterization of the genome of a novel poacevirus isolated from Zoysia matrella (Merrill) imported into the United States from Japan. The novel virus, tentatively named "zoysia mosaic virus" (ZoMV), is a single-stranded RNA virus with a genome of 9,728 nucleotides (nt) in length, encoding a large putative polyprotein of 3,119 amino acids (aa). The ZoMV genome is closely related to the triticum mosaic virus (TriMV; FJ263671) genome, with 57.

Genomic characterization of silvergrass cryptic virus 1, a novel partitivirus infecting Miscanthus sinensis.

In the present study we report the identification of a novel partitivirus recovered from Miscanthus sinensis, for which the provisional name "silvergrass cryptic virus 1" (SgCV-1) is proposed. High-throughput sequencing (HTS) and rapid amplification of cDNA ends (RACE) allowed the assembly of the complete sequence of each double-stranded RNA genome segment of this novel virus. The largest dsRNA segment, dsRNA1 (1699 bp), was predicted to encode a viral RNA-dependent RNA polymerase protein (RdRp) with 478 aa, and dsRNA2 (1490 bp) and dsRNA3 (1508 bp) were predicted to encode putative capsid proteins (CPs) with 347 and 348 aa, respectively.
