Genome sequencing reveals the genetic architecture of heterostyly and domestication history of common buckwheat.

Common buckwheat, Fagopyrum esculentum, is an orphan crop domesticated in southwest China that exhibits heterostylous self-incompatibility. Here we present chromosome-scale assemblies of a self-compatible F. esculentum accession and a self-compatible wild relative, Fagopyrum homotropicum, together with the resequencing of 104 wild and cultivated F.

Development and chromosomal characterization of interspecific hybrids between common buckwheat () and a related perennial species ().

Common buckwheat () is an annual self-incompatible plant that is widely grown. The genus comprises more than 20 species, including , a perennial that, unlike common buckwheat, is highly resistant to excess water. In this study, we developed interspecific hybrids between and via embryo rescue, to improve undesirable traits of common buckwheat, such as low tolerance to excess water.
