Abstract

The complete genomic sequences of six phenotypically distinct cherry leaf roll virus (CLRV) isolates from New Zealand were determined and compared. RNA1 and RNA2 are 7,919-7,921 and 6,361-6,363 nucleotides in length, respectively, excluding the poly(A) tails. Both genome segments contain a single open reading frame and encode one polyprotein of 2,113 amino acids for RNA1 and 1,590 aa for RNA2, with corresponding molecular masses of 235.5-236.1 kDa and 174.2-174.8 kDa, respectively. The six RNA1 sequences share 92.0-99.7 % nt and 97.0-99.5 % aa similarity, and the RNA2 sequences share 91.4-99.8 % nt and 94.3-99.7 % aa similarity. Phylogenetic analysis established close associations between the six New Zealand CLRV isolates and members of the subgroup C nepoviruses.
