Multiple alignment in the 5′-untranslated region of the newly defined phylogenetic group I nucleotide sequences revealed the presence of a significant insertion in the torque teno mini virus (TTMV) isolates TTMV-LY2 genome (a), which could form a stem-loop pattern in the predictive secondary structure (b). Residues that are identical among the sequences are given a black background. Lines between residues indicate deletions between the sequences. A: adenine; C: cytosine; G: guanine; T: thymine.
