This study reports the complete genomic sequence of a novel virus isolated from red clover. According to its genomic organization, its similarity to luteoviruses, and a greater than 10% difference in all genes, this virus isolate likely represents a new luteovirus species. As seen in nectarine stem pitting-associated virus (NSPaV) and NSPaV-South Korea (SK) luteoviruses, it differs from typical luteoviruses through the absence of ORF3a and ORF4 encoding movement proteins. Furthermore, its P5 protein (responsible for aphid transmission) is more similar to the P5 of enamoviruses than that of luteoviruses. The virus isolate has been named red clover-associated luteovirus (RCaV).
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.
