摘要

失落病毒是一种天然宿主范围窄、分布广泛的植物正义单链RNA基因组病毒。在本研究中，在公共领域的矮波兰小麦转录组组装组中发现了一种假定的新型clostervirus，即波兰小麦clostervirus (TriPCV)。TriPCV的基因组(15.36 kb;TPA Acc。不。编号:BK059767)含有9个开放阅读框(orf)，编码参与病毒复制、细胞间运动、衣壳化和抑制宿主RNA沉默的蛋白质。系统发育分析表明，TriPCV与其他clostervirus属成员有远亲关系。基于基因组组织、BLAST分析序列相似性、预测基序和系统发育，TriPCV可以被认为是clostervirus属的一个假定的新成员;波兰小麦;转录组;公共领域。

Dwarf polish wheat hosts a novel closterovirus: Revelation by transcriptome data-mining.

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.
