Abstract The functions of cell wall hydrolases and extensin on strawberry(Fragaria ananassa Duch.)fruit
ripening and softening were elucidated in this paper.The published genes that encoded relative enzymes or
extensin were depicted and evaluated.The key factors deciding strawberry ripening and softening were
cellulase,pectate lyase and extensin.The approach of enhancing strawberry fruit firmness was mentioned.The
technique of RNA interference could effectively regulate the vital gene and decrease the expression of the
relative enzymes mRNA.
