摘　　要：During the diversification of angiosperms, seeds have evolved structuralp chemical, molecular and physiolog- ically developing changes that specially affect the nucellus and endosperm. All through seed evolution, programmed celldeath （PCD） has played a fundamental role. However, examples of PCD during seed development are limited. The present review examines PCD in integuments, nucellus, suspensor and endosperm in those representative examples of seeds studied to date.During the diversification of angiosperms, seeds have evolved structuralp chemical, molecular and physiolog- ically developing changes that specially affect the nucellus and endosperm.
