Abstract/Notes Abstract In August 2016, a yellow vein disease was
observed on leaves of Euonymus bungeanus Maxim
(Euonymus, Celastraceae) in Liaoning, China. Virions
measuring 750 × 13 nm were observed in a sample from
the diseased plant. A potexvirus was detected in the sample
by small-RNA deep sequencing analysis and recovered by
traditional cloning. The genome of this potexvirus consists
of 7,279 nucleotides, excluding the poly(A) tail at the 3’
end, and contains five open reading frames (ORFs). Based
on the nucleotide and amino acid sequences of the coat
protein gene, the virus shared the highest sequence similarity
with white clover mosaic virus (WCMV, X16636)
(40.1%) and clover yellow mosaic virus (ClYMV, D00485)
(37.1%). Phylogenetic analysis showed that the virus
clustered with potexviruses and is most closely related to
strawberry mild yellow edge virus. These results indicate
that this virus is a distinct member of the genus Potexvirus,
for which the name euonymus yellow vein associated virus (EuYVAV) is proposed. To our knowledge, this is the first
report of a potexvirus on E. bungeanus.
