Abstract
losteroviruses are positive sense single-stranded RNA genome-containing plant viruses with narrow natural host range and wide distribution. In the present study, aputative novel closterovirus, Triticum polonicum closterovirus (TriPCV) was identified in the transcriptome assembled contigs of dwarf polish wheat available in public domain. The genome of TriPCV (15.36 kb; TPA Acc. No.: BK059767) contained nine open reading frames (ORFs) that encode for proteins involved in viral replication, cell-to-cell movement, encapsidation and suppression of host RNA silencing. Phylogenetic analysis revealed that TriPCV was distantly related to other members of the genus Closterovirus. Based on genome organization, sequence similarities in BLAST analysis, predicted motifs and phylogeny, TriPCV can be regarded as aputative novel member of the genus Closterovirus Keywords: Closterovirus; Triticum polonicum; transcriptome; public domain.
