Variation in Seed Protein Subunits among Species of the Genus Fagopyrum Mill
Seed protein subunits of 75 accessions belonging to 10 species of buckwheat (7 species of the big-achene group and 3 of the small-achene group) were studied by means of SDS-PAGE. The subunits varied greatly both within a species and among different species. The seven buckwheat species of the big-achene group have 42 different subunits whereas those of the small-achene group have only 16. Each buckwheat species has at least a few unique subunits, which could be used for species identification in the genus Fagopyrum. In the small-achene group, F. gracillipes and F. pleioramosum are closely related. Based on the number, distribution and cluster analysis of the seed protein subunits, common buckwheat, wild common buckwheat, F. esculentum var. homotropicum, F. zuogongense and F. megaspartanium are close to one another and tartary buckwheat, wild tartary buckwheat, F. plius, F. cymosum and F. giganteum are also close to each other, supporting the hypothesis that F. megaspartanium and F. pilus are ancestral species of common buckwheat and tartary buckwheat respectively.
