FIG 3.
Phylogenetic relationships of all SPgV variants discovered in this study. A PCR amplicon spanning the putative NS3 coding region of the SPgVver genome was sequenced from samples that tested positive for SPgV RNA by qRT-PCR that were not subjected to unbiased deep sequencing. Shown is a maximum likelihood tree, not rooted, with 1,000 bootstrap replicates. Black dots indicate splits that are supported by 100% of bootstrap replicates. Bootstrap values below 70 are not shown. The bar shows the calculated genetic distance.
