Indeed, CYMV causes the maximum damage to cowpea cultivars and it may cause yield reduction up to 80-100 % (Chant, 1959; and Williams, 1977). In the 50 years since it was first described, Cowpea mosaic virus (CPMV) has become one of the most intensely studied plant viruses. Dijkstra J, Bos L, Bouwmeester HJ, Hadiastono T, Lohuis H. 1987. The entire infectious virus particle, called a virion, consists of the nucleic acid and an outer shell of protein. Cowpea mosaic virus (CPMV) is a picorna-like plant virus. First, the addressabilty of carboxylates was demonstrated using a carboxylate-selective fluorescent dye, N-cyclohexyl-N‘-(4-(dimethylamino)naphthyl)carbodiimide. LiveRank. Popular. The Cucumber Mosaic Virus, named for the first plant it attacked, causes a lot of deaths among herbaceous and woody plant species. Virus diseases of herbaceous legumes have been relatively little studied even though the legumes play an important role in the maintenance of soil fertility and pest/disease management as well as providing fodder in sub-Saharan Africa. Crossref CAS Web of Science® Google Scholar; Padgett HS and Beachy RN (1993) Analysis of a tobacco mosaic virus strain capable of overcoming N gene-mediated resistance. Compared to yields of modern soybean (3,000 kg per hectare and up), peanut (2,000), or even cowpea grown on experiment stations and in countries such as India (at least 2,000), this is an appalling level Much of the difference is due to the fact that cowpea occupies only a small part of each hectare of the mixed cropping system.

Cowpea mosaic virus (CPMV) belongs to a group of viruses that cause a quite drastic modification by inducing the formation of a tubular structure in plasmodesmata. The techniques developed were used to screen 5000 cowpea lines for field resistance-to anthracnose, cercospora leaf spot, rust and bacterial pustule. Disease Resistance Most of the time, the viral and fungal attack to a crop lead to almost 100% of crop loss. Two key platforms are available: virus nanoparticles (VNPs) based on the complete CMPV virion, including the genomic RNA, and virus-like nanoparticles (VLPs) based on the empty CPMV (eCPMV) virion. The objective of the study was to determine the prevalence and identity of viruses infecting cowpea in the growing districts of Uganda. After preliminary observations on 5000 lines, 719 … Bonphace Collins Mangeni, PhD. Some of the most promising nano-scale scaffold systems have been co-opted from nature including plant viruses such as cowpea mosaic virus (CPMV). Most viruses have either RNA or DNA as their genetic material. Nanoparticle platforms are particularly attractive for theranostic applications due to their capacity for multifunctionality and multivalency. Often referred to as “poor man’s meat”, cowpea is one of the most important subsistence legumes cultivated in West Africa due to the high protein content of its seeds. Researchers have seen promising results by injecting dog and mouse tumors with the cowpea mosaic virus… Cowpea mosaic virus moves from cell‐to‐cell until it eventually reaches the phloem, which is utilized to invade the younger plant parts (long‐distance or vascular movement). Cowpea Mosaic Virus Capsid: A Promising Carrier for the Development of Carbohydrate Based Antitumor Vaccines. Fery RL, Dukes PD. In Kenya, cowpea yield is 0.53 tonnes/ha of dry seeds which is low compared to 1.86 tonnes/ha in USA. Viral diseases are among the major constraint to cowpea production, causing yield losses of up to 87 %. Major cowpea viruses include Cowpea Mild Mottle Virus (CPMMV), Cowpea aphid- borne mosaic virus (CABMV) and Cucumber Mosaic Virus (CMV).

Botanical Name : Vigna sinensisSavi. Cowpea stunt disease is caused by a synergistic interaction between blackeye cowpea mosaic virus (BlCMV) and cucumber mosaic virus (CMV). Cowpea mosaic virus (CPMV) is a plant virus that has been developed for multiple biomedical and nanotechnology applications, including immunotherapy. Two key platforms are available: virus nanoparticles (VNPs) based on the complete CMPV virion, including the genomic RNA, and virus-like nanoparticles (VLPs) based on the empty CPMV (eCPMV) virion. Cowpea mosaic virus From Wikipedia, the free encyclopedia Cowpea mosaic virus (CPMV) is a non-enveloped plant virus of the comovirus group. Infection of a susceptible cowpea leaf causes a "mosaic" pattern in the leaf, and results in high virus yields (1-2 g/kg). Plant Cell, 5, 577 – 586. For the first time, decoration of surface-exposed carboxylate groups on Cowpea mosaic virus particles is reported, thus increasing the number and types of addressable surface groups on this nanoscaffold. Research in the past 15 to 20 years has shifted from studying the underlying genetics and structure of the virus to focusing on ways in which it can be exploited in biotechnology. Very recently it has been shown that CPMV is loaded into both major and minor veins of the inoculated primary leaf, but was unloaded exclusively in major veins, preferably class III veins ( Silva et al ., 2002 ). cowpea crop is commonly grown in fields in the eastern and southern regions and harvested for fresh pods and dry grains.
