Fig 2. An optimal tree focusing on cluster 3 containing the stone fruit and apple 4bV isolates.

The tree was generated as in Fig 1 with a sum of branch length = 129.46875000 is shown. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches [32]. The tree is drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic tree. The evolutionary distances were computed using the number of differences method [33] and are in the units of the number of base differences per sequence. The analysis involved 13 nucleotide sequences. Codon positions included were 1st+2nd+3rd+Noncoding. All ambiguous positions were removed for each sequence pair. There were a total of 23545 positions in the final dataset. Evolutionary analyses were conducted in MEGA6.
