Figure 1From: Distinct evolutionary histories of the DNA-A and DNA-B components of bipartite begomovirusesPhylogenetic tree constructed from an alignment of 212 DNA-A component sequences of geminiviruses. The sequences used are representative of the 212 geminivirus species recognized as of December 2006. The scale at the basis of the diagram is the pairwise distance expressed as percentage dissimilarity.Back to article page
