Similar to Asian rice, African rice is a diploid A-type genome, having 12 chromosomes and an estimated size of ~358 Mb. Figure 4. We detected evidence for artificial selection at a genome-wide scale, as well as with a set of O. glaberrima genes orthologous to O. sativa genes that are known to be associated with domestication, thus indicating convergent yet independent selection of a common set of genes during two geographically and culturally distinct domestication processes.

Mol Ecol. There are only two species of cultivated rice in the world: Oryza glaberrima, or African rice, and Oryza sativa, or Asian rice.Native to sub-Saharan Africa, O. glaberrima is thought to have been domesticated from the wild ancestor Oryza barthii (formerly known as Oryza brevilugata) by peoples living in the floodplains at the bend of the Niger River some 2,000–3,000 years ago (1, 2). Despite its use, the long life cycle of Nipponbare makes it time-consuming for most genetic analyses.

Oryza glaberrima is the African cultivated rice species, domesticated from its wild ancestor by farmers living in Inland Delta of Niger River. It includes the major food crop rice (species Oryza sativa and Oryza glaberrima).Members of the genus grow as tall, wetland grasses, growing to 1–2 m tall; the genus includes both annual and perennial species. Several studies indicated that it has extremely narrow genetic diversity compared to both its wild progenitor, Oryza barthii and the Asian rice, Oryza sativa which can mainly be attributed to a severe domestication bottleneck.
