Figure 3

Co-linearity found within the Ranavirus genus. (A) FV3 and ATV, both members of the Ranavirus genus possess almost complete co-linearity of orthologous genes as visualized by a dotplot. However, 2 inversions have occurred. The FV3 genes 10–52 and 77–88 have switched genomic locations as shown, potentially through two recombination events. The inversion has also resulted in the loss of the ortholog of FV3 9L in ATV. (B) There is a limited amount of co-linearity found between FV3/TFV/ATV and SGIV/GIV. The co-linearity has been visualized using a dotplot analysis between FV3 (horizontal sequence) and GIV (vertical sequence). Genes are colored either red or blue representing right- or left-ward transcription respectively. (C) The co-linearity between FV3 and GIV is generally composed of stretches of 2 or 3 co-linear orthologous genes. Orthologous genes, in a co-linear arrangement are schematically shown as blocks of the same color on either FV3 or GIV genomic sequence.
