The splicing diagram and ORF map of TTV group 6 based on representative sequence TW53A26. Reading frames are indicated at left for both the splicing diagram and ORF map. (a) In the splicing diagram, arrow boxes indicate the three distinct reading frames. Putative splicing donor and acceptor sites are linked by dash lines. (b) In the ORF map, potential start codons (AUG) are indicated with a half-height line and stop codons (UGA, UAA, UAG) are indicated by full-height lines. (c) In the substitutions map, the vertical lines represent nucleotide substitutions compare with representative sequence TW53A26. Sequences that aligned to gaps of TW53A26 were removed and gaps that aligned to TW53A26 were counted as substitutions. * A C → T premature mutation at 523 bp was ignored here.
