摘要
The complete genome of a new umbra-like virus from edible fig (Ficus carica) was identified by high-throughput sequencing. Based on its similarity to umbra-like virus genome sequences available in GenBank, the proposed name of this new virus is “fig umbra-like virus” (FULV). The genome of full-length FULV-1 consists of 3049 nucleotides organized into three open reading frames (ORFs). Pairwise comparisons showed that the complete nucleotide sequence of the virus had the highest identity (71.3%) to citrus yellow vein-associated virus (CYVaV). In addition, phylogenetic trees based on whole-genome nucleotide sequences and amino acid sequences of the RNA-dependent RNA polymerase showed that FULV forms a monophyletic lineage with CYVaV and other umbra-like viruses. Based on the demarcation criteria of the genus Umbravirus, and lack of two umbravirus ORFs, we propose that FULV is a putative new member of the umbra-like virus clade within the family Tombusviridae.
