Solving the mystery of Obake rice in Africa: Population structure analyses of Oryza longistaminata reveal three genetic groups and evidence of both recent and ancient introgression... by Labroo, Marlee R., Clark, Lindsay V., Zhang, Shilai, Hu, Fengyi, Tao, Dayun, Hamilton, Ruaraidh Sackville, Sacks, Erik J.

“…This study identified three genetic subpopulations of O. longistaminata, which correspond geographically to Northwestern Africa, Pan-Africa, and Southern Africa. We confirmed that O. longistaminata is, perhaps counterintuitively, more closely related to the Asian species, O. sativa, than the African species O. barthii and O. glaberrima. …”

Efficiency of SNP and SSR-based analysis of genetic diversity, population structure, and relationships among cowpea (Vigna unguiculata (L.) Walp.) germplasm from east Africa and II... by Desalegne, B.A., Dagne, K., Gedil, Melaku A, Boukar, O., Fatokun, C.A.

“…The extent of genetic diversity and relatedness of cowpea germplasm from East Africa are poorly understood. A set of 13 microsatellites (SSR) and 151 single nucleotide polymorphisms (SNPs) markers were applied to assess the levels of genetic diversity in a sample of 95 accessions of local cowpea germplasm and inbred lines of Vigna unguiculata. …”
