Walp., is a diploid warm-season legume of critical importance as both food and fodder in sub-Saharan Africa. This species is also grown in Northern Africa, Europe, Latin America, North America and East/Southeast Asia. To capture the genomic diversity of domesticates of this important legume, de novo genome assemblies were produced for representatives of six sub-populations of cultivated cowpea identified previously from genotyping of several hundred diverse accessions. A total of 44,861 genes were identified in the resulting pan-genome, including 21,330 core and 23,531 non-core genes. Therefore, the total number of genes in the domesticated cowpea pan-genome is more than double the number of genes in any of the individual genomes. GO-Terms associated with response to stress, defense response in particular, were highly enriched among the non-core genes, while core genes were significantly enriched in terms associated with catabolic processes, transport an...
