Abstract
Kermode, A. R., Gifford, D. J. and Bewley, J. D. 1985. The role of maturation drying in the transition from seed development to germination. III. Insoluble protein synthetic pattern changes within the endosperm of Ricinus communis L. seeds.—J. exp. Bot. 36: 1928–1936. Immature seeds of Ricinus communis L. cv. Hale (castor bean) removed from the capsule at 30 or 40 days after pollination (DAP) can be induced to germinate by being subjected to drying. This desiccation–induced switch from development to germination is mirrored by a change, upon subsequent rehydration, in the pattern of insoluble protein synthesis within the endosperm storage tissue. During normal development from 25–40 DAP there is rapid synthesis of the insoluble (11S) crystalloid storage protein. At later stages of development (45 and 50 DAP), crystalloid protein synthesis declines markedly and synthesis of new insoluble proteins commences. Following premature drying at 30 or 40 DAP, the pattern of insoluble protein synthesis upon rehydration is virtually identical to that following imbibition of the mature seed. Proteins synthesized during normal late development (at 45 and 50 DAP) are produced up to 48 h after imbibition; a subsequent change in the pattern of insoluble protein synthesis occurs between 48 and 72 h. Thus, in contrast to the rapid switch in the pattern of soluble protein synthesis induced by drying, insoluble protein syntheses within the endosperm are redirected towards those uniquely associated with a germination/growth programme only after a considerable delay following mature seed imbibition, or following rehydration of the prematurely dried seed. Nevertheless, these results support our contention that drying plays a role in the suppression of the developmental metabolic programme and in the permanent induction of a germination/growth programme.
