Figure 4: Phylogenetic trees constructed from aligned complete nucleotide sequence of betasatellite associated with TbCSV-FB01, with other betasatellite sequences retrieved from NCBI ( using Neighbor-joining algorithm. Horizontal distances are proportional to sequence distances, vertical distances are arbitrary. The trees are unrooted. A bootstrap analysis with 1000 replicates was performed, and the bootstrap percent values more than 50 are numbered along branches.
