Analyses of Monomeric Storage Proteins "Gliadins" in Iranian Bread Wheats

A collection of new and obsolete Iranian bread wheat cultivars were characterized for gliadins using acid polyacrylamide gel electrophoresis (A-PAGE). Extensive polymorphism (H) = 0.734 in gliadin patterns was found. A total of 26 band patterns including 13, 8 and 5 different mobility bands were ide...

Description
Summary:A collection of new and obsolete Iranian bread wheat cultivars were characterized for gliadins using acid polyacrylamide gel electrophoresis (A-PAGE). Extensive polymorphism (H) = 0.734 in gliadin patterns was found. A total of 26 band patterns including 13, 8 and 5 different mobility bands were identified, in the zones of ω-, β + γ- and α-gliadins, respectively. There were a few patterns specific to each region and some were common among all the regions. Patterns of α-gliadin C, β + γ-gliadins A, and ω-gliadins H, C and E patterns were significantly higher in temperate and tropical zones. β + γ-gliadin C and ω-gliadin Q were significantly higher in Caspian-cold regions. Variation was observed in gliadins patterns of cultivars grown in different regions in Iran. Individual cultivars showed unique gliadin fingerprints. There were larger variation in ω- and γ + β-gliadins than in α-gliadins. These results may provide complementary information for relating genetic diversity, and quality characterization of Iranian wheat cultivars.
