Abstract:
We determined the complete genome sequence of a highly divergent South Korean (SK) isolate of a cherry-associated luteovirus (ChALV) from peach. The ChALV-SK genome consists of 5,815 nucleotides, and contains five open reading frames (ORFs). A comparative analysis of the full genome showed only 73.1% nucleotide sequence identity with a recently described ChALV from the Czech Republic (CZ). Amino acid similarities of the individual ORFs between ChALV-SK and other luteoviruses range from 17.3 to 92%, which places the new isolate close to the species demarcation value for luteoviruses. Results show our ChALV-SK isolate to be highly diverged from the ChALV-CZ isolate.
