|---|---|---|---|---|---|---|---|---|
| TTMV-G1 | 2889/2895 | 337/339–2725/2731 | ORF1–4 | 150/153–155/158 | 231/236–238/241 | 268/274–276/282 | 2721/2727–2726/2732 | 2838/2844–2889/2895 |
| TTMV-G2 | 2906/2915 | 337/343–2537/2543 | ORF1–3 | 151/154–156/159 | 231/237–236/242 | 269/275–277/283 | 2739/2742–2741/2747 | 2804/2807–2906/2915 |
| TTMV-G3 | 2836/2839 | 352/355–2669/2672 | ORF1–4 | 118/119–123/124 | 245/248–250/253 | 283/286–291/294 | 2664/2667–2669/2672 | 2728/2731–2836/2839 |
| TTV-G4 | 3856 | 227–3027 | ORF1–4 | 52–58 | 139–144 | 177–185 | 3023–3028 | 3094–3233 |
The nucleotide positions are variable due to different genomic lengths within the same virus species.
