Purification of Virus in Plants: 9 Main Steps

A large amount of infected plant material is needed to purify the virus. It can be achieved by inoculation of a water or buffer extract of the infected plant to a number of suitable hosts or to the same healthy host.

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 Virus-Like Particles (VLPs) from Plants

Abstract. 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 purified by isopycnic centrifugation which ...

Isolation and Cultivation of Viruses - Virology

Plant pathology also known as phytopathology is the scientific study of plant diseases caused by pathogens (infectious diseases) and environmental conditions (physiological factors). The use of plants to study virus is an expensive method. If viral growth occurs in the plant, there will be a reduce in quality and quantity of the crops.

Three modern serological methods to detect plant viruses

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].

Introduction to Plant Viruses, the Invisible Foe

Since plant viruses are obligate, biotrophic parasites, their life cycles start by penetration of the virion into the cell. Plant viruses are unable to penetrate the plant cuticle and cell wall. It is believed that the virion enters the cytoplasm of the cell passively through wounds caused by

Plant Viruses - Viral Transmission and Disease

03-11-2019  Plant viruses are particles of RNA or DNA that infect plants and cause disease. Most plant viruses are single-stranded RNA or double-stranded RNA viruses. Common plant viruses include mosaic viruses, spotted wilt viruses, and leaf curl viruses. Plant viruses are typically spread by either horizontal or verticle transmission.
