Phylogenomics provides comprehensive insights into the evolutionary relationships among cultivated buckwheat species.

ABSTRACT:

Background

Buckwheat belongs to the family Polygonaceae and genus Fagopyrum, which is characterized by high flavonoid content, short growth period, and strong environmental adaptability. Buckwheat has three cultivated species, including the annual food crops common buckwheat (Fagopyrum esculentum) and Tartary buckwheat (Fagopyrum tataricum), and the perennial traditional herbal medicine golden buckwheat (Fagopyrum cymosum). However, the unclear phylogenetic relationships among these three species based on genomic data limit buckwheat interspecific hybridization and genetic improvement.

Results

Despite their enormous differences in morphology and genome, we confirm the closet relationship between Fagopyrum cymosum and Fagopyrum tataricum, but not Fagopyrum esculentum. The res
