Variation in the performance of contrasting maturity class of cowpea cultivars (Vigna unguiculata L. Walp) in the derived Savanna By O.S. Cowpea (Vigna unguiculata L. Cowpea (Vigna unguiculata (L.) Walp. Cowpea is considered more tolerant to drought than soybeans and better adapted to sandy soils. 2. Nitrogen fertilizer application more than doubled cowpea grain yields compared with Fe only treatments which yielded 0.1 and 0.8 t ha −1 in Hwedza and Mutasa, respectively (see C1, Table 7; Figure 3A,B). Beans/Cowpea Farming Business Plan is a lucrative business that needs a lot of strategic Planning to start and a business coach like Dayo Adetiloye to help you start the … You could also enjoy the cowpea curry with steamed basmati rice. is cultivated widely in the tropics and has multipurpose uses: as food for human beings, fodder for livestock and atmospheric nitrogen fixers. Many cowpea cultivars have a vining growth habit, but modern plant breeding has also led to more upright, bush-type cultivars. This hybrid PDT-CPMV carrier system was effective in killing both melanoma cells and macrophages in vitro (Wen et al., 2016). The pinkeye pea, a variant of the blackeye, is the leading horticultural class of cowpea grown in the US. Multivalent display of antiviral molecules and carbohydrates on CPMV facilitated their usage for therapeutic applications (Lomonossoff and Evans, 2011; Koudelka et al., 2015; Hefferon, 2017). Cowpea, (Vigna unguiculata), annual plant within the pea family (Fabaceae) grown for its edible legumes. CHI1. However, recent advances in molecular biological techniques, genomics, and bioinformatics have been opening new vistas for molecular breeding in cowpea (Boukar et al., 2013; Diouf, 2011; Ehlers et al., 2012). Upon drying, the eye color darkens to a dark purple. Cowpea is traditionally important as an affordable source of protein and minerals and of cash income in sub-Saharan Africa, especially for small-scale farmers who have limited options for food and cash crops. This conjugation enabled specific targeting of CPMV to folate receptors (FRs) expressing HeLa and KB cells (Destito et al., 2007). Reddy, in Advances in Virus Research, 2014. Saute the onion in a pot. Native CPMV and CPMV particles derivatized with lanthanide metal complexes were found to be safe and nontoxic, based on the biodistribution, toxicity, and pathology studies of these particles in vivo (Rae et al., 2005; Singh et al., 2007). To overcome the dose-limiting nonspecific toxicities of trivalent chromium (a beneficial mineral nutrient), which can selectively inhibit the proliferation of high-glucose-induced human aortic smooth muscle cells (HASMC) in vitro, chromium chloride was loaded into the CPMV interior cavity via infusion, and the resultant CrCl3-loaded CPMV (CPMV-Cr) particles significantly reduced glucose-induced HASMC proliferation and presented antiatherogenic effects under hyperglycemic conditions (Ganguly et al., 2016). Further production occurs in the Mediterranean Basin, Southeast Asia, Latin America, and the United States. Cowpea is a legume whose grains are widely consumed as rich sources of protein and other nutrients in some parts of the continent. However, some cowpeas are harvested while the seed are high moisture, and sold fresh, typically referred to as southern peas. Some are short, upright bush types, and others are tall and vinelike. Hyv rinen 2010 and around student writing suggests a kind of transition genre within any frame- work for each grade level, in finland. Such empty capsids have been used to carry a wide range of cargo molecules, such as metals, fluorescent dyes, or drugs (Culver et al., 2015; Wen et al., 2015a; Narayanan and Han, 2017a). – cowpea Subordinate Taxa. It is a valuable crop as it is a highly palatable food source and the whole plant can be used as forage for animals. The size of the leaves is 6 to 16 x 4 to 11 cm and have many shapes vary from linear, lanceolate to ovate. Intratumoral delivery of magnetic nanoparticle (mNP) to induce hyperthermia and eCPMV in combination improved local and systemic tumor treatment efficacy (retardation of secondary tumor growth (abscopal effect) and resisting tumor rechallenge) in the C3H mouse/MTG-B mammary adenocarcinoma and C57-B6 mouse/B-16-F10 melanoma cancer cell models (Hoopes et al., 2017a). Vigna unguiculata (Cowpea) Status. Chitinase class 4. It also discusses the main objectives of cowpea breeding, breeding methods, and strategies of cowpea. Cowpea is also planted in mixtures with corn, sorghum, sudan grass, and other crops. Researchers, however, found a high level of random amplified polymorphic DNA marker diversity in landraces from Malawi. The fact that they are a food crop rather than a feed crop can buffer a farmer’s economic risk from variability in weather or commodity crop prices. These efforts have facilitated the use of CPMV particles as optical probes, vaccine candidates, and memory and sensor nanodevices (reviewed in Young et al., 2008; Destito et al., 2009; Grasso and Santi, 2010; Steinmetz, 2010; Lomonossoff and Evans, 2011; Wen et al., 2015a; Zhang et al., 2016; Lee et al., 2016b; Narayanan and Han, 2017a). Beans/Cowpea Farming Business Plan in Nigeria. In Arlingtom line, cowpea extreme resistance to CPMV is controlled by a dominant locus designated Cpa. LOW QUALITY PROTEIN: phenylalanine ammonia-lyase class 1 … It is also known as Bachapin Bean, Southern Pea Black Eyed Cowpea, Black Eyed Dolichos, Poona Pea Black-Eyed Pea, Rope Bean Black-Eyed Bean, Red Pea China Bean, Marble Pea, Common Cowpea, Macassar Bean, Cowgram, Cowpea, Kafir Bean, Cultivated African Cowpea, … The seed pod is typically 3 to 6 inches long and has 6 to 13 seeds per pod. Preclinical studies in a carotid artery photochemical injury model of thrombosis confirmed thrombus homing of the nanoprobes, with the elongated TMV rods exhibiting significantly greater attachment to thrombi than icosahedral CPMV (Wen et al., 2015b,c). They would probably mature too late for double cropping in northern Missouri. And cowpea tolerates droughts, which are increasing across sub-Saharan Africa. Protocols for screening germplasm for resistance by mechanical inoculation and/or natural infection facilitated by vectors under field conditions have been reported (Gillaspie, 2007; Goenaga, Quiles, & Gillaspie, 2008). Walp.) By continuing you agree to the use of cookies. For some markets, the cowpeas must be harvested at a higher moisture, such as 18%, and trucked directly from the field to the processor. I.R.A.P. All cultivated cowpea varieties are considered warm season and adapted to heat and drought conditions. In nature, transmission is usually by leaf-feeding beetles, especially by members of the Chrysomelidae. Cream - seeds are cream colored and not crowded in the pods. Textural class Sandy soil also be an indicator of the response of cowpea lines to low P soils. Using the amounts recommended from soil tests for soybeans would be appropriate. However, row crop cultivation may be necessary with cowpeas, depending on the weed pressure, soil conditions, and rainfall. Incorporation of unnatural amino acids into CPMV capsid was carried through multiple orthogonal chemistries (such as chemoselective hydrazone ligation strategy and copper-catalyzed azide-alkyne cycloaddition (CuAAC) or “click” reaction). It is one of the most ancient human food sources and has probably been used as a crop plant since Neolithic times. Community College of Allegheny County, Pittsburgh, PA, United States. However, resistance to multiple virus infection is scarce in cowpea, and recent studies are putting greater emphasis on multiple virus resistance. This article has been rated as GA-Class. Cowpea grains rich in protein are consumed in different forms in several parts of the tropics. The seed weight per bushel is 60 pounds with about 3,000 to 4,000 seeds per pound. Cowpea has a number of common names, including … These efforts have already resulted in identification of multiple virus resistance to three virus species (BCMV-BlCM, CMV, and SBMV) in breeding lines, IT98K-1092-1 and IT97K-1042-3 (Ogunsola, Fatokun, Boukar, Ilori, & Kumar, 2010). The particles were negatively stained with 2% (w/v) uranyl acetate. 4 The International Board for Plant Genetic Resources (IBPGR) is an autonomous, international scientific organization under the aegis of the Consultative Group on International Agriculture Research (CGIAR). Seed should be innoculated with the appropriate Rhizobium species for optimum nitrogen fixation, but nodules will generally form on cowpeas. Now it is a broadly adapted and highly variable crop, cultivated around the world primarily as a pulse, but also as a vegetable (both for the greens and the green peas), a cover crop, and for fodder. However, these intensive efforts are limited to a few viruses, viz., BCMV-BlCM, CABMV, CMV, and CGMV. All rights reserved. Cowpea also known as Vigna unguiculata is a legume of the family Fabaceae ⁄ Leguminosae. However, ex situ collection of cowpea and wild Vigna germplasm from different parts of the world were assembled in the IITA gene bank. 13. Growing cowpea is fairly straight forward, with management practices being similar to soybeans. (IPM CRSP, 2000). LOC114181557 class I heat shock protein-like [ (cowpea)] Gene ID: 114181557, updated on 15-Aug-2019. It is a 30 nm icosahedral virus and consists of bipartite positive-sense, single-stranded RNA genome with each RNA molecule encapsidated in a separate particle. ssp. The yardlong bean is an intensely cultured, trellised vegetable crop that is grown widely in southeast Asia. The whole plant is used as forage for animals, with its use as cattle feed likely responsible for its name. Cowpea is well adapted to stress and has excellent nutritional qualities. It is known internationally as lubia, niebe, coupe or frijole. If there are any tough ones, use just their seeds. The immunosuppressive tumor microenvironment enables cancer to resist immunotherapies. It is the second most important food legume after groundnut (Boukar, Bhattacharjee, Fatokun, Kumar, & Gueye, 2013). Abstract. Experts agree that cowpeas belong to the botanical species Vigna unguiculata (L.) Walp. Yield information is available on the varieties released from these programs. People consume cowpea as a vital source of protein after cooking. High levels of resistance to several cowpea viruses, especially multiple virus infections are limited in cowpea germplasm. Cowpea is one of the most ancient crops known to man, with its center of origin and subsequent domestication being closely associated with pearl millet and sorghum. Application of DNA marker technologies for cowpea improvement has been very slow when compared to many other crops. CPMV was first isolated from an infected cowpea (Vigna unguiculata) plant in Nigeria in 1959. Major cowpea viruses include Cowpea Mild Mottle Virus (CPMMV), Cowpea aphid- borne mosaic virus (CABMV) and Cucumber Mosaic Virus (CMV). Experimentally, CPMV is mechanically transmissible. Plant populations in wide rows should be similar to soybeans, about 4 to 8 plants per foot of row. Cowpea mosaic virus (CPMV; Comovirus, Comoviridae) is the most extensively studied platform for various conjugations and biotechnological applications. Lacks conserved residue(s) required for the propagation of feature annotation. The plant's Family is Fabaceae. For instance, resistance to CGMV in crosses between IT97K-499-25 × Canapu T16 was shown to be controlled by a single dominant gene (Rodrigues, Santos, & Santana, 2012). • Germination of cowpea is better between 12-15°C, whereas proper growth and development takes place between 27-350 C . With the exception of CGMV and CCMV, all the other viruses are known to be seed-transmitted at a variable rate between none to 55% depending on virus strain, cowpea genotype, and time of infection (Bashir & Hampton, 1996; Salem, Ehlers, Roberts, & Ng, 2010). Introduction. ssp. It is an important crop in Africa, its probable center of origin, but is also grown in Brazil, India, Southeast Asia, and the United States. These recent developments in cowpea transformation form a basis for strong cowpea genetic improvement program to enhance cowpea productivity. Due to the presence of highly symmetrical and heteromeric nature of the capsid, CPMV provides a remarkable opportunity to differentially introduce (at fivefold or threefold or both positions) multiple types of functionalities by specific genetic and chemical engineering with control over both the spatial distribution and the degree of multivalency (Uchida et al., 2007; Young et al., 2008; Steinmetz, 2010; Wen et al., 2016). Cowpeas are a very important legume crop in many parts of Asia, Africa, and other arid parts of the world. Many cowpea varieties with high yield potential have been developed and adopted by the farmers. Additionally, serological and nucleic acid-based diagnostic tools (Amayo et al., 2012; El-Kewey, Sidaros, Abdelkader, Emeran, & EL-Sharkawy, 2007; Naimuddin, 2010; Ojuederie, Odu, & Ilori, 2009; Roy & Malathi, 2004; Salem et al., 2010) have contributed to the sensitive detection and rapid evaluation of cowpea germplasm, leading to identification of acceptable levels of resistance by a number of research groups around the world (reviewed in Hampton & Thottappilly, 2003). Cultivars differ in terms of biomass partitioning to grain and phenology. 1. Agriculture, farming, agricultural products and crops classification, biology, open study site for all subjects even serving as online dictionary Pest and diseases of cowpea … Some buyers will want the seed cleaned and bagged, while others will take the grain in bulk form and clean it themselves. A variety of birds, including wild turkey, eat the seeds and the plant can be used by quail as cover. Cowpea also has different seed coat colors such as black, red, and cream. CPMV was first isolated from infected cowpeas (Vigna unguiculata) in Nigeria in 1959. Overall, dried black-eyed or pink-eyed/purple hull peas can be looked at as another crop to diversify the crop base on a farm. The seed pods are borne above the leaf axil, making the pods very visible. Proximate analysis of cowpea CHAPTER ONE/INTRODUCTON Background to the Study Cowpeas (Vigna unguiculata and Vigna Senensis) are important grain legumes in East and West Africa as well other developing countries (Dovlo et al. For the cowpea seed market, quality of seed is important, so care in harvest and post-harvest handling may be important to avoid cracked or split seed. While its natural host is cowpea, it can infect other legumes and Nicotiana benthamiana has proven to be an extremely valuable experimental host. This resulted in the identification of only TVNu1158 as the best aphid-resistant accession for incorporation into cultivated cowpea, while other accessions were found to be susceptible to aphid infestation and severe damage (Souleymane et al., 2013). Many cowpea varieties with high yield potential have been developed and adopted by the farmers. Cowpea is primarily used in the form of dry seeds, fodder, green pod, green manure, and cover crops. It is a subsistence crop, often intercropped with sorghum, maize and pearl millet. Soil pH should be 6.0 or higher. They include BCMV-blackeye cowpea mosaic strain (BCMV-BlCM), Cowpea aphid-borne mosaic virus (CABMV), Cowpea chlorotic mottle virus (CCMV), CMV, Cowpea golden mosaic virus (CGMV), Cowpea mottle virus (CPMoV), CPMV, CPSMV, and Southern bean mosaic virus (SBMV; Table 9.1). Despite a large number of cowpea accessions (about 15,000) maintained at the International Institute of Tropical Agriculture (IITA), recent studies demonstrated that genetic diversity in cultivated cowpea is low. Preplant tillage can greatly help reduce early weed pressure, or cover crops such as rye can potentially be used for weed control. Bean and cowpea leaves (6 g FW) frozen in liquid nitrogen were used for total RNA extraction . And because the crop can be harvested within two months of sowing, it fills the “hunger gap” for poor families between May and August when other crops, such as maize, are still young in the field. These genetic resources have been explored to identify new traits and to develop elite cowpea varieties. The Plants Database includes the following 5 subspecies of Vigna unguiculata . Yields in the U.S. are reported at 900 to 1,350 pounds per acre, but up to 2,700 pounds per acre in California. For optimum yield, cowpeas should be planted in early June in Missouri, although planting dates from late-May through mid-June are appropriate. They are often cooked with water and canned or frozen. Vigna unguiculata (Cowpea) Status. There are cowpea breeding programs throughout the primary production areas, which include Arkansas, California, Texas and southeastern states. Cowpea (Vigna unguiculata [L.] Walp.) Concerning Cladosporium vignae, causal organism of leaf and pod spot of cowpea (Vigna unguiculata) and leaf blight of Lespedeza bicolor. The Plants Database includes the following 27 species of Vigna .Click below on a thumbnail map or name for species profiles. Choice of market class, and approach to narrow or wide rows can affect which variety to choose. Copyright © 2021 Elsevier B.V. or its licensors or contributors. Other commonly used names include asparagus bean, sitao, bodi bean, and snake bean. These lists are believed to be accurate, but given the changing nature of herbicide registrations, labels and relevant government regulations should be checked before applying any pesticide. The average grain yield of cowpea in West Africa is approximately 492 kg ha−1, which is much lower than its potential yields. The study on antioxidant activity of cowpea had been investigated by Siddhuraju and Becker (2007), and they reported that cowpea extract has the potential antioxidant activity using different methods such as superoxide anion and hydroxyl radical-scavenging activities, DPPH, ABTS, and FRAP. Click here for a crop budget for cowpea (PDF). We have established that intratumoral administration of plant-derived Cowpea mosaic virus (CPMV) nanoparticles as an in situ vaccine overcomes the local immunosuppression and stimulates a potent anti-tumor response in several mouse cancer models and canine patients. is one of the most important drought-resistant leguminous food crops grown for its foliage and grain in tropical and sub topical Saharan Africa regions of the world particularly in Nigeria , .There are variations among cowpea genotypes in their drought tolerating potentials [3, 4].Turk et al. CPMV symptoms and particles (A) Mosaic symptoms on the trifoliate leaves of a CPMV-infected Vigna unguiculata plant (right) compared to an uninfected plant (left). 52 000, 58 000, and 63 000 in roughly equal amounts. Cowpea mosaic virus (CPMV) is the type member of the genus Comovirus which includes 13 additional members in the family Comoviridae. BCMV-BlCM, CABMV, and CMV were detected in the majority of cowpea producing countries. IITA conserves over 14,000 accessions of cultivated cowpea in its gene bank, and the USDA has duplicates of most of the IITA cowpea lines for safe keeping (Boukar et al., 2013; Dumet et al., 2012). However, a number of diseases and pests are reported in other locations, and active breeding has taken place for resistant varieties. Email . Utilizing CPMV capsid for templated fabrication of metallic nanoparticles by an electroless deposition (ELD) and mineralization by a variety of processes allowed the production of thin layers of metals and alloys with uniform thickness and composition. Various soups and bean mixes will incorporate this product as well. The grain provides valuable protein and the leaves are used as a nutritious vegetable. This low productivity is due to a host of diseases, insects, pests, parasitic weeds, drought, poor soils and low plant population density in the farmer’s field. "Coronet", a pink-eyed/purple hull type, has been the variety most commonly grown in the southeast Missouri. Most mice rechallenged with tumors on the opposite flank completely rejected the rechallenged tumor (Lizotte et al., 2016). However, some cowpeas are harvested while the seed are high moisture, and sold fresh, typically referred to as southern peas. Introduction to Growing Cowpeas. The relatively fast maturity of cowpeas allows their use as a double crop after wheat or canola in southern Missouri. SOM, P. HAZRA, in Genetic Improvement of Vegetable Crops, 1993. The seed should be planted similar to soybeans, at 1 to 1 1/2 inches deep. Transient coexpression of CPMV precursor (VP60) that consists of fused large and small proteins and 24K proteinase for proteolytic processing of VP60 in plants resulted in CPMV VLPs (eCPMV), which were completely devoid of RNA (either virus or host) (Saunders et al., 2009). 1. Cowpea research paper for executive resume writing service chicago. The immature seeds, when cooked, are a medium to dark brown, very tender and have a delicate flavor. Mycotaxon, 43:9-20 CPMV can be purified in large quantities from infected leaves and is stable at wide range of temperatures (up to 60°C) and in the pH range of 3.0–9.0 and can withstand some organic solvents (Steinmetz et al., 2009). Crowder peas - seeds are black, speckled, and brown or brown-eyed. The beetle vectors can acquire the virus by feeding for as little as one minute and can retain and transmit the virus for a period of days or weeks.
