Effect of postharvest treatment of calcium and auxin on cell wall composition and expression of cell wall-modifying genes in the Chilean strawberry (Fragaria chiloensis) fruit

► Postharvest treatments of calcium and auxin in Chilean strawberry fruit. ► Calcium and auxin as modifiers of cell wall and gene expression. ► Calcium treated fruit exhibits high content of ionic pectins during cold storage. ► Auxin treatment induces high transcript level of XTH1 gene after cold storage. ► Combined treatment down regulates PG1, PL and EG1 gene expression after cold storage.
