Gliadins are the major influence factors of wheat processing quality, which determine dough extensibility. On the basis of the electrophoretic mobility by acidic polyacrylamide gel electrophoresis, gliadin can be separated into α-,β-,γ- andω-gliadin. Among them, α-gliadins are the most abundant and accounted for 15%~30% of the wheat storage proteins. On the other hand, α-gliadins can cause different diseases. The present study aimed at cloning and analyzing the α-gliadin genes from Aegilops searsii, express...

醇溶蛋白是小麦种子中的主要贮藏蛋白之一,约占小麦胚乳贮藏蛋白总量的50%~60%[1],是影响小麦加工品质的重要因素。在酸性电泳中,根据迁移率大小可将其分为α-,β-,γ-,ω-醇溶蛋白[2,3]。其中,α-醇溶蛋白占小麦籽粒总蛋白的15~30%[4-6],平均分子量为31 k D,主要由位于第六同?
