    01-01-1986· Propagation and purification procedures for specific viruses can be found in the Review of Plant Pathology or in the Commonwealth Agricul- tural Bureaux~Association of Applied Biologists, Descriptions of Plant Viruses. Most plant viruses occur in lower concentrations than those described here and, consequently, require more rigorous purification.

    Isolation of viruses by electro-extraction of infected plants.

    The isolation of viruses from infected plant material by a process termed electro-extraction appeared to be a convenient and simple method of obtaining viruses in a fair state of purity. The method has the advantage over the conventional methods of virus purification that the infected plant tissue is not disintegrated and that organic solvents such as chloroform and butanol are avoided.

    Purification of Virus-Like Particles (VLPs) from Plants

    Viral coat proteins expressed in plants often form virus-like particles (VLPs) which are good vaccine candidates as they are safe and highly immunogenic and can be easily purified. The VLPs can be purified by rate-zonal density centrifugation which is based on the size of the VLP or they can be puri

    Groundnut plants with chlorotic rosette disease contain a manually transmissible virus, groundnut rosette (GRV), which is also transmitted in the persistent (circulative) manner by aphids (Aphis craccivora ), but only from plants that are co‐infected with a manually non‐transmissible luteovirus, groundnut rosette assistor virus (GRAV).Strains of GRV from plants with chlorotic or green

    Three modern serological methods to detect plant viruses

    10-10-2019· Traditional diagnosis of plant viruses requires bioassay, an indicator plant, determination of host range, symptomatology, virus particle morphology (size and shape), and vector relations [2,3]. A single diagnostic test or assay may provide adequate information on the identity of a virus but a combination of methods is generally needed which are specific, sensitive and inexpensive [4,5].

    Plant virus Wikipedia

    Plant viruses need to be transmitted by a vector, most often insects such as leafhoppers.One class of viruses, the Rhabdoviridae, has been proposed to actually be insect viruses that have evolved to replicate in plants.The chosen insect vector of a plant virus will often be the determining factor in that virus's host range: it can only infect plants that the insect vector feeds upon.

    Purification of viruses by electrophoresis in sucrose

    Zone electrophoresis (ZE) in concentration gradients of sucrose proved to be a powerful technique in the purification of viruses although it is seldomly used as a single step for the separation of the infective agent from extraneous matter but usually as a final procedure. No difficulties were exper

    Plant viruses cause considerable economic losses and are a threat for sustainable agriculture. The frequent emergence of new viral diseases is mainly due to international trade, climate change, and the ability of viruses for rapid evolution. Disease control is based on two strategies: i) immunization (genetic resistance obtained by plant breeding, plant transformation, cross-protection, or
