The complete nucleotide sequence of potato virus T

The complete nucleotide sequence of potato virus T Potato virus T (PVT), a member of an unassigned species in the family Flexiviridae, has a genome 6,539 nt in size with three ORFs coding for replication-associated proteins (185 kDa, ORF 1), movement protein (40 kDa, ORF 2) and coat protein (24 kDa, ORF 3), respectively. PVT differs from the type members of all genera of the family Flexiviridae with a 30K-type movement protein and is phylogenetically distant from all of these viruses, least so from grapevine virus A (GVA, genus Vitivirus ), with which it groups in all trees. The viral genome resembles that of trichoviruses but is smaller and does not contain the 3′ terminal fourth ORF found in some members of this genus. PTV may represent a new genus of plant viruses for which the provisional name of Andesvirus is proposed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

Potato virus T (PVT), a member of an unassigned species in the family Flexiviridae, has a genome 6,539 nt in size with three ORFs coding for replication-associated proteins (185 kDa, ORF 1), movement protein (40 kDa, ORF 2) and coat protein (24 kDa, ORF 3), respectively. PVT differs from the type members of all genera of the family Flexiviridae with a 30K-type movement protein and is phylogenetically distant from all of these viruses, least so from grapevine virus A (GVA, genus Vitivirus ), with which it groups in all trees. The viral genome resembles that of trichoviruses but is smaller and does not contain the 3′ terminal fourth ORF found in some members of this genus. PTV may represent a new genus of plant viruses for which the provisional name of Andesvirus is proposed.
