Disrupting insect-mediated transmission of plant viruses
Many plant viruses are vectored by aphids in the non-persistent mode, in which virus particles are transported on these insects’ specialised piercing mouthparts (stylets). Virus infection can change plant-vector interactions and it is thought that this may accelerate virus transmission. To better …

Animal and Plant Viruses with Double-Stranded Ribonucleic Acid
<p>Reoviruses occur widely in the respiratory and enteric tracts of man and animals, but their relation to disease is not clear. The present study concerns the physical-chemical characteristics and interaction with cells of reovirus type 3. A main objective of the study is to relate some of the …

The binding of divalent cations to tobacco mosaic virus and to some isometric plant viruses
… ions, which stabilised compact forms of these viruses. The phenomenon of cation binding is thus not limited to TMV. In the light of published evidence, it appears that most if not all plant viruses are able to bind divalent cations, which thus represent a hitherto disregarded stabilising …

The epidemiology and management of fungal- and nonpersistent aphid-borne plant viruses in a Mediterranean type climate
… for various non-persistently aphid-borne viruses of grain legumes, celery and carrots and for the fungally-transmitted lettuce big vein disease (LBVD). In a range of legumes, extreme resistance to Alfalfa mosaic virus (AMV) was found in Vicia faba cv. Ascot, Hedysarum coronarium cv. …

Persistent RNA Viruses of Common Bean (Phaseolus vulgaris): Distribution and Interaction with the Host and Acute Plant Viruses
… bean can be infected with acute and persistent plant viruses. A modified dsRNA extraction method was developed and used in this study. The method was fast, economic, versatile, and required relatively small amounts of desiccated plant tissue. The method was successfully used to extract dsRNAs …

A Multivalent Ligand Display System with Plant Viruses: A Novel Approach Towards Studying Spatial Effects of Cell Adhesion Ligands
… number of researchers are introducing viruses as primary building blocks to generate ornate nanomaterials for a wide-range of applications. The viruses possess highly ordered structures with well-characterized three-dimensional structures at near-atomic resolutions, batch to batch …

Determination of the molecular mechanism of cell-to-cell movement in squash leaf curl geminivirus
The intercellular spread of plant viruses is an essential process with extensive implications for the life cycle of the virus, and the cell biology of the host. In all plant viruses, intercellular spread is accomplished by a special class of viral encoded protein, termed movement proteins (MPs). …

Cellular Functions of the Squash Leaf Curl Geminivirus Movement Proteins BL1 and BR1
Plant viruses encode what are typically called movement proteins (MPs). These are defined as proteins dispensable for viral replication and encapsidation, but essential for cell to cell movement of the virus to the phloem and eventually leading to systemic infection of the plant. Unlike most plant …

UNDERSTANDING THE POTENTIAL IMPACT OF CLIMATE CHANGE ON
… more than 700 million people globally. Cassava viruses and their vector (B. tabaci) are one of the greatest constraints to cassava production. Among the insect pests of cassava, B. tabaci stands out as an economically important pest, causing direct damage to a wide range of crops by producing …

EVOLUTIONARY AND MECHANISTIC INTERACTIONS IN VIRUS TRANSMISSION BY APHIDS
… that have co-evolved over years of interaction: plant hosts, aphid vectors, plant viruses and the aphid’s bacterial endosymbiont. In this interaction, plant hosts activate their immune defenses against plant viruses and aphids and the latter two use a myriad of strategies to overcome, counteract …

Plant virus detection and diversity in a mixed tree fruit orchard determined through metagenomic-based analysis of honeybee (Apis mellifera) collected samples
… fruit orchards where profitability of individual plants can take years to achieve. Over time, fruit trees can accumulate various viruses, leading to complex mixed infections. Furthermore, emerging viruses can create epidemics causing significant losses. Effective monitoring approaches can reduce …

The effect of varying mixtures of soybean and cereals on the landing rates of aphid vectors and spread of soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV)
… of foregut-borne non-persistently transmitted plant viruses such as soybean mosaic virus (SMV) and maize dwarf mosaic virus (MDMV), and also on the landing rates of the aphid vectors that transmit them. The uniqueness of this study is that it gives an insight as to how the same aphids spread …

Persistent viruses in Capsicum annuum plants: Understanding the mystery guests
Most work on plant viruses focuses on their pathogenicity, but recent studies suggest viruses may benefit their hosts, at least under some conditions. Plant-infecting viruses of the Partitiviridae and Endornaviridae are transmitted only vertically, via pollen and seed, generally cause no disease …

Evaluation and annotation of Bemisia tabaci transcriptome data using paired-end RNA sequencing
… food security crops, transmits more than 100 plant viruses. Despite its global importance as one of the world’s top 100 invasive species, limited genomic resources are available in public domains. In this study, transcriptomic datasets from cassava and non-cassava colonizing B. tabaci …

A study of the molecular variability of some South African isolates of tobacco necrosis virus
The relationship of various tobacco necrosis viruses, isolated from various crops and other sources in South Africa was determined. An isolate from avocado was chosen for partial characterisation to confirm that it was a member of the Necrovirus group of plant viruses. TNV was detected in potatoes …

Synthesis and Microscopic Characterizations of Virus Nanoparticle-Based Composite Materials
<p>Plant viruses and virus-like protein cages (VLPs) have shown significant promise for a wide range of biomedical applications. In contrast to the artificial nanomaterials, VLPs exhibit unique properties including their well-organized three dimensional (3D) structures, monodispersity, …

The Interaction Between Eukaryotic Translation Initiation Factor eIF4G and 3’ Cap Independent Translation Element of Barley Yellow Dwarf Virus Is Affected by Multiple Initiation Factors
… cap as well as a 3’poly A tail. Like many plant viruses, BYDV contains a cap independent translation element (CITE) in the 3’ untranslated region of the viral mRNA. BTE (Barley Yellow Dwarf Virus like cap-independent translation element) is one of the well characterized CITEs. BTE mediated …

Characterization of an Amphipathic Alpha-Helix in the Membrane Targeting and Viral Genome Replication of Brome Mosaic Virus
Positive-strand RNA viruses associate with specific organelle membranes of host cells to establish viral replication complexes. The replication protein 1a of brome mosaic virus associates strongly with the nuclear endoplasmic reticulum (ER) membranes, invaginates membranes into the lumen, and …
