Phylogenetic analysis of STIV with other iridovirus isolates based on four conserved core genes and the complete genome sequence. (A) Complete amino acid sequences of major capsid protein (ORF096R), myristilated membrane protein (ORF055R), DNA polymerase (ORF063R) and ribonuclease III (ORF087L) of STIV, FV3, TFV, ATV, SGIV, GIV, LCDV-C, LCDV-1, CIV, IIV-3, ISKNV, RBIV and OSGIV were aligned using Clustal-X and parsimony bootstrap trees generated using PHYLIP. Numbers above branches indicate bootstrap support values based on 100 replicates. (B) Unrooted phylogenetic tree of vertebrate iridoviruses based on the complete genomic sequences. Alignments were made using the MAFFT 6 program and a dendrogram was constructed using the MEGA4 program.
