Abstract
In 1993 a virus causing red mosaic and leaf distortion has been isolated from black bryony Tamus communis in Italy Based on particle properties and serology the virus was assigned to the genus Potexvirus and named Tamus red mosaic virus TRMV pending a genome sequence The original Italian TRMV isolate was submitted to the DSMZ plant virus collection PV0397 To confirm the taxonomic status of the virus the entire genome sequence was determined comprising 6495 nucleotides excluding the polyAtail Five putative open reading frames ORFs in an arrangement typical for potexviruses were predicted TRMV is closely related to but distinct from Clover yellow mosaic virus and Allium virus X In addition to previous morphological and serological characterization the results presented in this study further reinforce the classification of TRMV as a distinct virus species of the genus PotexvirusThe authors are grateful to P Caciagli and O Lovisolo Instituto di Fitovirologia Applicata Torino Italy for providing the TRMV isolate in 1993 and to the Department of Genome Analysis of the Helmholtz Centre for Infection Research Braunschweig for providing an excellent sequencing service
