The complete genome of a Watermelon silver mottle virus (WSMoV) (genus Tospovirus, family Bunyaviridae) isolate (WSMoV-GZ) from Guangdong province, China was sequenced. The genomes of WSMoV-GZ contained 3,603, 4,909, and 8,914 nt of small (S), medium (M), and large (L) RNA segments, respectively, and had a genomic organization characteristic of members of the genus Tospovirus. The amino acid sequence of the nucleocapsid (N) protein, S RNA-encoded nonstructural (NSs) protein, M RNA-encoded nonstructural (NSm) protein, Gn/Gc glycoprotein precursor, and RNA-dependent RNA polymerase (RdRp) protein showed 94.3-97.5 % identity with those of other WSMoV isolates. Phylogenetic analysis showed that the N protein of WSMoV-GZ was clustered together with those of the WSMoV isolates. The full sequence of WSMoV-GZ provides a reference genome for comparison with other tospoviruses.
