One of the major allergenic proteins in common buckwheat (Fagopyrum elculentum) was found to be a BW10KD. In this work, allergenic BW10KD genomic DNAs from the native common buckwheat ‘Pyeongchang’ and Tartarian buckwheat ‘Clfa47’ were cloned by polymerase chain reaction (PCR), and their nucleotide sequences were determined. In addition, a novel PCR assay targeting the allergenic BW10KD gene was developed to detect and differentiate both buckwheat species in food. The nucleotide sequences of the BW10KD genomic DNA from ‘Pyeongchang’ and ‘Clfa47’ were 94% identical. Base differences in the nucleotide sequences of the BW10KD genes are probably useful as a molecular marker for species-specific identification. The ‘Pyeongchang’-specific primer set 154PF/400PR and the ‘Clfa47’-specific primer set 154DF/253DR generated 247 and 100 bp fragments in singleplex PCR, respectively. A duplex PCR assay with 2 species-specific primer sets simultaneously differentiated the ‘Pyeongchang’ and ‘Clfa47’ in a single reaction. The PCR assay also successfully allowed for the rapid detection of buckwheat ingredients in foods.
