Complete nucleotide sequence of a new variant of grapevine fanleaf virus from northeastern China

Complete nucleotide sequence of a new variant of grapevine fanleaf virus from northeastern China The complete RNA1 and RNA2 sequences of a new grapevine fanleaf virus isolate (GFLV-SDHN) from northeastern China were determined. The two RNAs are 7,367 and 3,788 nucleotides (nt) in length, respectively, excluding the poly(A) tails. Compared to other GFLV isolates, GFLV-SDHN has a 22- to 24-nt insertion in the RNA1 5′ untranslated region, and there was 19.1-20.1 % and 11.7 %–13.0 % sequence divergence in RNA1, and 15.5 %–20.5 % and 8.5-13.5 % in RNA2, at the nt and amino acid level, respectively. Phylogenetic analysis revealed that the origins of GFLV-SDHN are distinct from those of other GFLV isolates.

Abstract

The complete RNA1 and RNA2 sequences of a new grapevine fanleaf virus isolate (GFLV-SDHN) from northeastern China were determined. The two RNAs are 7,367 and 3,788 nucleotides (nt) in length, respectively, excluding the poly(A) tails. Compared to other GFLV isolates, GFLV-SDHN has a 22- to 24-nt insertion in the RNA1 5′ untranslated region, and there was 19.1-20.1 % and 11.7 %–13.0 % sequence divergence in RNA1, and 15.5 %–20.5 % and 8.5-13.5 % in RNA2, at the nt and amino acid level, respectively. Phylogenetic analysis revealed that the origins of GFLV-SDHN are distinct from those of other GFLV isolates. One recombination event was identified in the 2AHP region of RNA2 in GFLV-SDHN.
