Figure 19

Unrooted radial bootstrapped tree for VPE-like proteins based on PHYLIP analyses using Zea See2 (UniProt CAB64545) as the reference sequence. Representative genera are shown, together with E values, indicating the numerical expectation that the alignment with the reference sequence has arisen by chance. Support values (in red) were determined by bootstrap analysis (Additional file 1o). Branch lengths are proportional to number of amino acid substitutions per position. Additional file 2o gives branch length values and confidence limits from the PROML outfile.
