title: Characterization of a potyvirus isolated from Tradescantia fluminensis in northern Italy.
abstract: We isolated a potyvirus from Tradescantia fluminensis that was causing leaf distortion and mild mosaic. We cloned and sequenced a 1500 bp cDNA obtained by RT-PCR corresponding to the 3' proximal region of the genome. We determined the host range and tested a series of potyviral antisera against our tradescantia virus isolate by immuno-enzymatic methods. Based on our results, we suggest that our viral isolate could be considered a new potyvirus species named Tradescantia mild mosaic potyvirus. Phylogenetic analysis confirmed that Tradescantia mild mosaic virus belongs to the genus Potyvirus within the family Potyviridae, but the virus could not be assigned to any of the potyvirus groupings recently defined.
