Translation of viral proteins from subgenomic RNAs (sgRNAs) is a common strategy among positive-stranded RNA viruses. Unlike host mRNA, sgRNA of Potato leafroll virus (PLRV) does not possess a cap at its 5' end nor a poly(A) tail at the 3' terminus, both of which are known to be crucial for translation of RNA in eukaryotic cells. Here, we demonstrate, that in wheat germ extract (WGE) truncation...

Strains of peanut stunt cucumovirus (PSV) were classified into two distinct subgroups, I and II, based on Western and Northern blot analyses using antisera and cloned cDNA probes to strains PSV-ER and PSV-W. These results were corroborated by nucleotide sequence analyses of full-length cDNA clones of RNA3 from representative strains of the two subgroups. Whereas the percentage nucleotide sequen...

Dynein axonemal light intermediate chain 1 (dnali1) is an important part of dyneins and plays role in the growth development animals. However, there little information about dnali1 fish. Herein, we cloned gene from genome olive flounder (Paralichthys olivaceus), a commercially maricultured fish China, Japan, Korea, analyzed its expression patterns different gender The DNA sequence contained 771...

Viruses provide valuable insights into the regulation of molecular processes. Brome mosaic virus (BMV) is one of the simplest entities with four viral proteins and three genomic RNAs. Here we report that the BMV capsid protein (CP), which functions in RNA encapsidation and virus trafficking, also represses viral RNA replication in a concentration-dependent manner by inhibiting the accumulation ...

We previously showed that ribosomal protein L13a is required for translational silencing of gamma interferon (IFN-gamma)-induced ceruloplasmin (Cp) synthesis in monocytes. This silencing also requires the presence of the GAIT (IFN-gamma activated inhibitor of translation) element in the 3' untranslated region (UTR) of Cp mRNA. Considering that Cp is an inflammatory protein, we hypothesized that...

Objective(s):OCT4 is a transcription factor required for pluripotency during early embryogenesis and the maintenance of identity of embryonic stem cells and pluripotent cells. Therefore, the effective expression regulation of this gene is highly critical. UTR regions are of great significance to gene regulation. In this study, we aimed to investigate the potential regulatory role played by 5´UT...

Abstract The neurotrophin Brain-derived neurotrophic factor (BDNF) is encoded by multiple bipartite transcripts. Each BDNF transcript composed one out of 11 alternatively spliced exons containing the 5′untranslated region (UTR), and common exon encompassing coding sequence (CDS) 3′UTR with two variants (short long). In neurons, mRNA have a distinct subcellular distribution, constituting “spatia...

one of the most efficient mechanisms by which plants protect themselves from invading virusesis the specific rna-dependent silencing pathway termed post-transcriptional gene silencing(ptgs). in this mechanism, resistance to a virus is engineered through the expression of asegment of the virus genomein transgenic plants. potato virusy (pvy) is one of the mostdamaging viruses of potato, infecting...
