“Rose yellow leaf virus (RYLV), a pathogen
whose nearly complete nucleotide sequence has been
determined recently [25], is considered an isolate of
RrLDV (and not a member of a separate species) on the
basis of the high sequence identity shared by their corresponding
proteins (90 %, 95 %, 82 %, and 86 %, respectively,
for RdRp, CP, MP1 and MP2) [33].”
RrLDV is the abbreviation given for “Rosa rugosa leaf distortion virus”
