The evolution and organization of multigene families exemplified by the hordein genes in barley
Hordein, the seed storage protein in barley, is encoded by a multigene family. All wild and cultivated species of the Hordeum genus were investigated electrophoretically and imunologically for their hordein composition. The reactions of specific monoclonal antibodies showed that particular polypeptide regions have been conserved throughout the genus. Some of the regions could also be recognize in
