Figure 4From: Insertion Sequences show diverse recent activities in Cyanobacteria and ArchaeaThe bootstrapped neighbor-joining phylogenetic tree of 31 archaea based on 16S RNA genes. It is rooted by E. coli K12. The number in parentheses after an organism name is the number of annotated raIS elements in that organism. The phylogenetic tree is constructed by MEGA version 3.1 [50].Back to article page
