Abstract
SDS-Polyacrylamide gel electrophoresis of glutelin fraction reveals that dry grains of American, Basmati and Al-Hassawi rice varieties tested have the same pattern of the major polypeptides of 14, 15-18, 26-31 and 45-51 KD. However, three major polypeptides vary in their degree of expression. These cultivars vary in the number of minor high molecular weight polypeptides . American and Basmati rice have a 75 KD polypeptide which is not expressed in Al-Hassawi rice varieties. However, Al-Hassawi rice varieties have a polypeptide with a MW of 59 KD which is not expressed in American and Basmati rice.
