用酸-聚丙烯酰胺凝胶电泳法测定了日本普通小麦系麦胶蛋白的电泳带型。在本研究使用的107个小麦品系中，鉴定出27种不同的模式，其中13种对应于ο-麦胶蛋白，8种对应于β， γ-麦胶蛋白，6种对应于α-麦胶蛋白。日本小麦品种和地方品种的麦胶蛋白模式与其他国家小麦品系的麦胶蛋白模式有很大差异，日本小麦品系的变异仅限于46种。在日本的7个采集或繁殖地区，麦胶蛋白的分布频率不同。将麦胶蛋白模式与高分子量麦胶蛋白亚基组合相结合，共观察到67个组合。一种由ο-麦胶蛋白模式F、β、γ-麦胶蛋白模式H和α-麦胶蛋白模式d组成的麦胶蛋白模式在许多日本小麦品系中经常发现，而其他模式仅限于一两个小麦品系。
The electrophoretic banding patterns ofgliadin in common wheat lines derived fromJapan were determined byacid-polyacrylamide gel electrophoresis. For the 107 wheat lines used in our study,27 different patterns were identified, 13corresponding to the ο-gliadin, 8 tothe β, γ-gliadin and 6 to theα-gliadin. The gliadin patterns ofJapanese wheat cultivars and landracesgreatly differed from the patterns of wheatlines from other countries, and thevariation seen in wheat lines from Japanwas limited to 46 patterns. Sevencollection or breeding areas in Japanshowed different frequencies in theirgliadin patterns. Combining the gliadinpatterns with high molecular weightglutenin subunit compositions, 67combinations were observed. One gliadinpattern consisting of ο-gliadinpattern F, β, γ-gliadinpattern H and α-gliadin pattern Dwas frequently found in many Japanese wheatlines, though the other patterns werelimited to only one or two wheat lines.
