Complete genome sequence of a putative novel alphaendornavirus isolated from Fagopyrum esculentum in South Korea
Archives of Virology(2022)
摘要
The complete genome sequence of a putative new virus isolate, provisionally named “Fagopyrum esculentum endornavirus 2” (FeEV2), is 15,706 nucleotides long with a single, large open reading frame and a typical endornavirus genome organization. FeEV2 shares 19.4%–22.1% nucleotide sequence identity with other known endornavirus genome sequences. The putative polyprotein, RNA-dependent RNA polymerase (RdRp), helicase, and glycosyltransferase (GT) share 10.6%–24.3%, 30.4%–66.1%, 16.3%–45.7%, and 10.1%–21.6% amino acid sequence identity, respectively, with the homologous sequenced proteins from known endornaviruses. This suggests that it is a member of a new, distinct species. Phylogenetic analysis of RdRp sequences places FeEV2 with other Alphaendornavirus genus members (family Endornaviridae ). This is the first report of the complete genome sequence of FeEV2, which was isolated from Fagopyrum esculentum in South Korea.
