To facilitate the transfer of the viral genomes to neighboring cells, RNA viruses produce proteins interacting with and modifying plasmodesmata [41,42]. This is achieved with the assistance of so-called viral-encoded movement protein(s) (MPs) and/or coat proteins (CPs) binding to the viral ...

Furthermore, the inherent responses of Csm to either viral RNA or its transcription makes the Csm-based detection suitable for both RNA and DNA viruses. Importantly, the viral activated RNase activity can be disproportionally amplified through supplied oligonucleotides. Despite these promises, it is ...
2010), additional important information about the virus was acquired using EM and proteomic and RNA knockdown studies in EPC cells (Li et al. 2014b; Ma et al. 2014). These types of studies can provide valuable information on virus replication, which may in turn prove useful for developing ...

类病毒是一种具有传染性的单链RNA病原体,比病毒还要小,而且没有蛋白质外壳。类似于类病毒的活性遗传物质,在获取了几个结构蛋白之后,获得了从一个细胞内出来并进入另一个细胞的能力,于是就演化成了穿梭于细胞间的具有感染性的病毒。 另一些科学家则认为,病毒的起源是个倒退的过程。病毒是具有细胞的有机物退化...

(Step 4) or some might fail to enter the nucleus and be degraded (Step 4f). Once vRNPs are inside the nucleus, virus replication is then initiated. For both viruses, as the number of copies of viral RNA and proteins grow during replication, it becomes increasingly unlikely that the cell...
