Structure of genetic diversity in the gene pool of Azuki bean.

The Azuki bean,Vigna angularis var. angularis, is one of the important beans in East Asia. Despite the great economic and cultural importance of Azuki bean, its geographical and domestication process is poorly understood. Here, we examine genetic diversity of domesticated azuki bean and it’s wild relatives V. angularis var. nipponensis, weedy azuki and V. nakashimae using five nuclear genes. The neighbor-joining analysis revealed that domesticated Azuki bean is related to two genetically distinct wild populations groups. The first group includes V. angularis var. nipponensis and domesticated Azuki bean which are distributed in the Himalayan highlands and Southwest China. The second group consists V. nakashimae, Korean population of V. angularis var. nipponensis, and domesticated Azuki bean. These geographically distant populations in the Azuki bean gene pool will reflect the genetic composition and evolutionary history of the Azuki bean.
