Figure 2

Phylogenetic relationships between the five iridovirus genera based on gene content. Individual viral species were compared within a genus to identify the number of orthologous genes. Orthologous genes between viral genera were then determined. The numbers on each line identify the number of orthologous genes shared between viral species or genera including the 26 core genes. The Iridovirus and Chloriridovirus genera have a high degree of gene conservation and a combined genera box (Iridovirus/Chloriridovirus) was used to compare orthologous genes between genera. In addition, two subgroups of the Ranavirus genus are shown. Each subgroup contains a virtually identical complement of genes. However, a comparison between the FV3/TFV/ATV subgroup with the SGIV/GIV subgroup revealed 72 orthologous genes.
