Unrooted radial bootstrapped protein sequence tree for senescence-related amino acid permeases based on PHYLIP analyses using Auxenochlorella dee4 (UniProt Q9XFY8) 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 1g). Branch lengths are proportional to number of amino acid substitutions per position. Additional file 2g gives branch length values and confidence limits from the PROML outfile.
