Alternative Mechanisms to Initiate Translation in Eukaryotic mRNAs

International Journal of Genomics, Volume 2012, Issue 1, 2012., 2012
The composition of the cellular proteome is under the control of multiple processes, one of the most important being translation initiation. The majority of eukaryotic cellular mRNAs initiates translation by the cap‐dependent or scanning mode of translation initiation, a mechanism that depends on the recognition of the m7G(5′)ppp(5′)N, known as the cap.

Melon necrotic spot virus Replication Occurs in Association with Altered Mitochondria

Molecular Plant-Microbe Interactions, 2015
Melon necrotic spot virus (MNSV) (genus Carmovirus, family Tombusviridae) is a single-stranded, positive-sense RNA virus that has become an experimental model for the analysis of cell-to-cell virus movement and translation of uncapped viral RNAs, whereas

First Report of Hibiscus Chlorotic Ringspot Carmovirus in Tuvalu

Plant Disease, 1998
In September 1997, plants of Hibiscus manihot (locally called nambele) were observed on Vaitupu Island, Tuvalu, exhibiting an angular leaf mosaic and chlorosis that was not always clearly discernible. Electron microscopy of negatively stained sap from affected leaves revealed the presence of numerous isometric virus particles 28 nm in diameter.

A Dual Interaction Between the 5′- and 3′-Ends of the Melon Necrotic Spot Virus (MNSV) RNA Genome Is Required for Efficient Cap-Independent Translation

Frontiers in Plant Science, 2018
In eukaryotes, the formation of a 5′-cap and 3′-poly(A) dependent protein–protein bridge is required for translation of its mRNAs. In contrast, several plant virus RNA genomes lack both of these mRNA features, but instead have a 3′-CITE (for cap ...

Interactions of viruses in Cowpea: effects on growth and yield parameters

Virology Journal, 2007
The study was carried out to investigate the effects of inoculating three cowpea cultivars: "OLO II", "OLOYIN" and IT86D-719 with three unrelated viruses: Cowpea aphid-borne mosaic virus (CABMV), genus Potyvirus, Cowpea mottle virus (CMeV), genus ...

The nucleotide sequence of cowpea mottle virus and its assignment to the genus Carmovirus

Journal of General Virology, 1995
The genome of cowpea mottle virus (CPMoV) is a positive ssRNA of 4029 nucleotides with six major open reading frames (ORFs). A non-coding region of 34 nucleotides precedes the first AUG. ORF1 encodes a 25 kDa polypeptide of unknown function and ORF2 encodes a 56 kDa putative RNA replicase.

The genome organization of pea stem necrosis virus and its assignment to the genus Carmovirus.

Intervirology, 2003
The complete sequence of the single-stranded, positive-sense RNA genome of pea stem necrosis virus (PSNV) has been determined. The 4,048-nucleotide genome contains five open reading frames (ORFs). The 5'-proximal ORF encodes a 25-kD protein (p25). If the amber termination codon is read through, the ORF produces a read-through protein of 84 kD (p84 ...

Additive interactions of unrelated viruses in mixed infections of cowpea.

Frontiers in Plant Science, 2015
This study was carried out to determine the effects of single infections and co-infections of three unrelated viruses on three cowpea cultivars (one commercial cowpea cultivar White and 2 IITA lines; IT81D-985 and TVu76). The plants were inoculated with

Cellular chaperones and folding enzymes are vital contributors to membrane bound replication and movement complexes during plant RNA virus infection.

Frontiers in Plant Science, 2012
Cellular chaperones and folding enzymes play central roles in the formation of positive strand and negative strand RNA virus infection. This article examines the key cellular chaperones and discusses evidence that these factors are diverted from their ...

Risk assessment of Retithrips syriacus for the EU

EFSA Journal, Volume 22, Issue 4, April 2024.
Abstract Following a request from the European Commission, the EFSA Panel on Plant Health performed a quantitative risk assessment for the EU of Retithrips syriacus (Mayet) (Thysanoptera: Thripidae), a polyphagous thrips, regarded as a tropical/subtropical pest occurring in several countries of Africa, South America, Asia and in the EU in Cyprus.
