Variable positions in the tufA amino acid pattern among the Ulotrichales. The abbreviations of amino acids followed the IUPAC nomenclature. The unique positions of the genera and species are highlighted in yellow and green, respectively. Asymmetric positions (not unique for only one genus) are marked in orange. The given numbers in the top represented the amino acid position in the tufA gene, the numbers below were the positions in the alignment. The accession numbers in bold were newly sequenced in this study.
