Abstract excerpt

Cowpea (Vigna unguiculata L. Walp.) is an Africa-originated legume providing a vital source of protein for millions across resource constrained areas of Africa, Asia and Latin America. Understanding genetic diversity in cowpea is pivotal to its genetic improvement. Here, we assemble 20 high-quality genomes representing cowpea global diversity and construct a graph-based pan-genome to characterize genetic...
