Molecular characterization and taxonomy of Grapevine leafroll-associated virus 7
Archives of Virology 157 (2), 359-362
Abstract: The complete nucleotide sequence of an Albanian isolate of grapevine leafroll-associated virus 7 (GLRaV-7-Alb) was determined. The viral genome consists of 16,404 nucleotides and has nine open reading frames (ORFs) that potentially encode proteins, most of which are typical for members of the family Closteroviridae. Only the 25-kDa (ORF8) and 27-kDa (ORF9) proteins had no apparent similarity to other viral proteins in the sequence databases. The genome structure of GLRaV-7-Alb closely resembles that of little cherry virus 1 and cordyline virus 1. In phylogenetic trees constructed with HSP70h sequences, these three viruses cluster together in a clade next to that comprising members of the genus Crinivirus, to which they are more closely related than to the clostero- and ampeloviruses. The molecular properties of these three viruses differ sufficiently from those of members of the three extant genera of the family Closteroviridae to warrant their classification in a novel genus.
