Abstract
losteroviruses are positive sense single-stranded RNA genome-containing plant viruses with narrow natural host range and wide distribution. In the present study, a putative 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 a putative novel member of the genus Closterovirus Keywords: Closterovirus; Triticum polonicum; transcriptome; public domain.
期刊介绍：
Acta virologica is an international journal of predominantly molecular and cellular virology. Acta virologica aims to publish papers reporting original results of fundamental and applied research mainly on human, animal and plant viruses at cellular and molecular level. As a matter of tradition, also rickettsiae are included. Areas of interest are virus structure and morphology, molecular biology of virus-cell interactions, molecular genetics of viruses, pathogenesis of viral diseases, viral immunology, vaccines, antiviral drugs and viral diagnostics.
