Phylogenetic tree of Tic20. A maximum-likelihood tree drawn from 125 characters with bootstrap values for 100 replicate trees shows that Tic20 proteins form two distinct clades. The first clade (green line) contains PsTic20 orthologs. Each Viridiplantae genome surveyed is represented here. The second clade (red line) contains the cyanobacterial homologs, as well as a subclade that contains Tic20-like proteins.
