Figure 2From: Avian reovirus L2 genome segment sequences and predicted structure/function of the encoded RNA-dependent RNA polymerase proteinPhylogenetic tree analyses of the prototype ARV L2 genome segments and homologous genes in other reoviruses. Abbreviations are as defined in the legend to Fig. 1. Lines are proportional in length to nucleotide substitution. Alignments were performed by Neighbor-Joining and tested with 1000 bootstrap replicates in MEGA version 4 [51].Back to article page
