Pakistan rice genetic resources-III: SDS-page diversity profile of glutelins (seed storage protein)

Abstract

Rice grain quality characters pertaining to seed storage proteins profile for glutelin was evaluated for diversity within Pakistan local rice genetic resources using SDS PAGE. Materials consisted of 475 accessions collected from 3-rice cultivation zones and other parts of the country. A wide variation was found in the glutelin fraction of rice protein at 57kD pro-glutelin and 40kD glutelin acidic subunit bands 3 and 4. The enriched glutelin variation at 57kD may be used in the development of improved protein cultivars with respect to quality and quantity.
