Journal ArticleDOI
Cowpea (Vigna unguiculata L. Walp.)
TL;DR: Development of cultivars with multiple resistances to biotic and abiotic stresses is an important current breeding objective and Earliness, delayed leaf senescence, and indeterminate growth habit are characteristics which are being combined to improve drought adaptation.
Journal ArticleDOI
A consensus genetic map of cowpea [Vigna unguiculata (L) Walp.] and synteny based on EST-derived SNPs
Wellington Muchero,Ndeye N. Diop,Prasanna R. Bhat,Raymond D. Fenton,Steve Wanamaker,Marti Pottorff,Sarah Hearne,Ndiaga Cisse,Christian Fatokun,Jeffrey D. Ehlers,Philip A. Roberts,Timothy J. Close +11 more
TL;DR: The development and validation of a high-throughput EST-derived SNP assay for cowpea, its application in consensus map building, and determination of synteny to reference genomes are reported, which support evolutionary closeness betweencowpea and soybean and identify regions for synteny-based functional genomics studies in legumes.
Journal ArticleDOI
Identification and comparative analysis of drought-associated microRNAs in two cowpea genotypes
Blanca E. Barrera-Figueroa,Lei Gao,Ndeye N. Diop,Zhigang Wu,Jeffrey D. Ehlers,Philip A. Roberts,Timothy J. Close,Jian-Kang Zhu,Jian-Kang Zhu,Renyi Liu +9 more
TL;DR: Deep sequencing small RNA reads from two cowpea genotypes that grew under well-watered and drought stress conditions suggest that miRNAs may play important roles in drought tolerance incowpea and may be a key factor in determining the level of droughtolerance in different cowpeA genotypes.
Journal ArticleDOI
Development of cowpea cultivars and germplasm by the Bean/Cowpea CRSP
Anthony E. Hall,Ndiaga Cisse,Samba Thiaw,Hassan O.A. Elawad,Jeffrey D. Ehlers,Abdelbagi M. Ismail,Richard L. Fery,Philip A. Roberts,L. W. Kitch,Larry L. Murdock,Ousmane Boukar,R.D. Phillips,Kay H. McWatters +12 more
TL;DR: In this paper, the authors reviewed accomplishments in cowpea cultivar and germplasm development by the bean/cowpea Collaborative Research Support Program (CRSP) which was funded by the United States Agency for International Development for a period of about 20 years.
Journal ArticleDOI

TL;DR: Fundamental genome resources and their application to the analysis of germplasm currently in use in West African breeding programs help to define goals and accelerate the breeding of improved varieties to address food security issues related to limited-input small-holder farming and climate stress.
