Phylogenetic relationship of 07V063. Phylogenetic trees were derived from multiple sequence alignments using Phylip v3.67. Bootstrapping was performed 500 times using SEQBOOT. Pairwise distances between DNA and/or protein sequences were determined with DNAdist and PROTdist, respectively. Neighbour-Joining (NJ) trees were calculated with NEIGHBOUR and Maximum Likelyhood (ML) trees with DNAML and PROML. Majority rule consensus trees were calculated using CONSENSE. The percentage confidence is indicated on the branches (500 datasets). Trees, constructed using NJ method, based on ORF5 DNA (A) or ORF1a (Nsp2) DNA (B) sequences. Strain 07V063 is underlined. VR-2332 was used as outgroup.
