Molecular evidence that the aphid-transmitted Tomato mild mottle virus belongs to the Potyviridae family but not the Potyvirus genus.
Molecular studies have been carried out on Tomato mild mottle virus (TMMV) and 2322 nucleotides of the aphid-transmitted virus have been sequenced. This translates to a 2187 nucleotide open reading frame and a 135 nucleotide untranslated region (UTR) followed by a poly A tail. The sequence is consistent with the NIb and coat protein regions of a member of the Potyviridae family of viruses. Sequence comparisons show this virus to have no close relationship with any previously sequenced aphid-transmitted virus; the highest identity was found with the whitefly-transmitted Ipomoviruses. The vector of transmission and the low level of sequence identity with other aphid-transmitted viruses suggest TMMV does not belong to any existing genus of the Potyviridae family.
