Accumulation of 52 kDa glycine rich protein in auxin-deprived strawberry fruits and its role in fruit growth. [Fragaria ananassa]
Growth of strawberry (Fragaria ananassa Duch) receptacles can be stopped at any stage by deachening the fruits and can be resumed by exogenous application of auxin. In their earlier studies they demonstrated auxin regulated polypeptide changes at different stages of strawberry fruit development. Removal of achenes from fruits to deprive auxin resulted in the accumulation of 52 KDa polypeptide. This polypeptide is associated with cell wall and its concentration is increased in a time-dependent manner in auxin deprived receptacles. Incorporation studies with (/sup 35/S) methionine showed the promotion of labelling of 52 kDa polypeptide in the auxin-deprived receptacles within 12 h after removal of the achenes. Amino acid analysis revealed that the 52 KDa polypeptide is rich in glycine. Their studies, with normal and mutant strawberry receptacles, indicate that the synthesis and accumulation of this glycine rich protein correlates with cessation of receptacle growth. These results suggest a role for the glycine rich protein in growth.
