Identification and characterization of a new member of the genus Luteovirus from cherry.

The complete genomic sequence of a new virus from cherry trees was determined. Its genome is 5857 nt long and resembles that of members of the genus Luteovirus in its genomic organization and nucleotide sequence. Based on the species demarcation criteria for luteoviruses, the virus represents a new luteovirus species. Furthermore, a 47-nt-long inverted repeat was found at the 3' end of its genome. The virus has been provisionally named cherry-associated luteovirus (ChALV) and is the fourth member of the family Luteoviridae reported to naturally infect woody plants.
