Turnip crinkle virus (TCV) is a plant pathogenic virus of the family Tombusviridae. It was first isolated from turnip (Brassica campestris ssp. rapa). TCV is a small (4054 nucleotides), single-stranded, positive-sense RNA virus (viral RNA is in the same orientation as mRNA).

2023年9月4日 · 芜菁皱缩病毒（Turnip crinkle virus, TCV）属于番茄丛矮病毒科麝香石竹斑驳病毒属，是正义 单链RNA病毒 。其中，P38不仅是结构蛋白，编码外壳蛋白（Coat protein, CP），还是沉默抑制子，可抑制宿主PTGS的免疫功能。

为了研究WUS介导的干细胞抗病毒免疫是否具有广谱性，该研究还检测了其他三种植物病毒：芜菁皱缩病毒 (Turnip crinkle virus, TCV)、烟草脆裂病毒 (tobacco rattle virus, TRV) 和芜菁花叶病毒 (turnip mosaic virus, TuMV)，得到了一致的结论，说明WUS介导的抗病毒免疫可以针对多种 ...

2016年4月18日 · Turnip crinkle virus (TCV) is a carmovirus that infects many Arabidopsis ecotypes. Most studies mainly focused on discovery of resistance genes against TCV infection and...

Most plant viruses encode suppressors of RNA silencing (VSRs) to protect themselves from antiviral RNA silencing in host plants. The capsid protein (CP) of Turnip crinkle virus (TCV) is a well-characterized VSR, whereas SUPPRESSOR OF GENE SILENCING 3 (SGS3) is an important plant-encoded component of …

2019年5月1日 · As effectors in the RNA silencing pathway, ARGONAUTE (AGO) proteins are targeted by some VSRs, such as that encoded by Turnip crinkle virus (TCV). A VSR-deficient TCV mutant was used to identify AGO proteins with antiviral activities during infection.

Among this group, satRNAs of turnip crinkle virus (TCV) and cucumber mosaic virus (CMV) are the best characterized. The 356-nt satRNA C of TCV has been reported to enhance TCV-induced symptoms by interfering with virion formation ( Sun and Simon, 2003 ).

2003年2月1日 · All of the protein products of Turnip crinkle virus (TCV; Tombusviridae, Carmovirus) were tested for their ability to suppress RNA silencing of a reporter gene after transient expression in Agrobacterium-infiltrated Nicotiana benthamiana leaves. Only the capsid protein, P38, showed suppression activity, although this was not obvious when P38 ...

2021年8月25日 · Here, we report a viral lncRNA that is produced by the replication machinery of turnip crinkle virus (TCV). This lncRNA, designated ttsgR, shares the terminal characteristics with TCV genomic and subgenomic RNAs and overaccumulates in the presence of moderately overexpressed TCV RNA-dependent RNA polymerase (RdRp).

The study demonstrates that turnip crinkle virus (TCV) infection enhances the expression of Arabidopsis Dcp1 (AtDcp1), which negatively regulates the accumulation of TCV RNA, indicating its involvement in antiviral defense.
