Development of RNA-free particles of Cowpea mosaic virus for applications in Nanotechnology
… efficient production of RNA-free particles of Cowpea mosaic virus (CPMV) has been developed. These are generated by co-expression of the precursor of the coat proteins (VP60) and the viral proteinase (24K) using the highly-efficient plant expression system, CPMV-HT, in the model plant Nicotiana …

A genomic analysis of the insect pest populations of cowpea in West Africa
Cowpea [Vigna unguiculata (L.) Walp (Fabaceae)] is an important and major staple food crop in sub-Saharan Africa, especially in the dry savanna regions of West Africa. The crop provides food, cash, and fodder. As a food crop, cowpea is a primary source of protein for the ever-growing population of …

N₂ fixation, plant mineral nutrition and C metabolites in cowpea/maize cropping systems
… quantify N₂ fixation in sole and mixed cropped cowpea, (2) To access nutrient assimilation by component species in the cropping system, and (3) to determine the effects of cropping system on C metabolites. At harvest the dry mass of both cowpea and maize were highest in sole crops. There was a …

Genetic analysis of cowpea (Vigna unguiculata L. WALP) agronomic variables in phosphorus limiting soil.
Cowpea is an important cultivated grain legume pulse, vegetable and fodder crop of African origin. However, yields have been characteristically low as a result of both abiotic and biotic stresses. Among the abiotic stresses, yield losses due to phosphorus (P) deficiency is an important factor. …

Initiation of translation of the small RNA of the cowpea strain of tobacco mosaic virus
Several features of the initiation of translation of CcTMV-SRNA were investigated. First, the site of initiation of translation was found to be the first AUG in the 5$\sp\prime$-terminal sequence m$\sp7$GpppGUAUUUGAUGAUGGCA ... despite the fact that this AUG codon is not found within a favorable …

Impacts of pesticide use practices and gender on cowpea productivity of smallholder farmers in Benin
Cowpea has a considerable potential to contribute to the food security and livelihoods of African smallholder farmers. Yet, cowpea yields in Africa are among the lowest in the world and one possible explanation for the yield gap is cowpea’s high vulnerability to insect pest attacks. Pesticides have …

Site-Directed Mutagenesis of Southern Bean Mosaic Virus (Cowpea Strain): in Search of a Viral Protease
The second and largest open reading frame within the southern bean mosaic virus (SBMV) genome encodes a 105 kDa polyprotein. Following translation, the polyprotein is cleaved to liberate various proteins necessary for SBMV replication. The elements within polyproteins of the picornavirus …
