Figure 6From: Evolutionary history of the poly(ADP-ribose) polymerase gene family in eukaryotesPhylogenetic analysis of Clade 3 PARP genes. The represented tree is a ML tree. This tree is based on a multiple alignment that includes the PARP catalytic domain (Additional file 8). Clade 3 proteins can be divided into six subclades A-F as indicated. Branch supports as in Figure 1. Scale bar indicates genetic distance reflected in branch length.Back to article page
