Expression of expansin gene, MiExpA1, and activity of galactosidase and polygalacturonase in mango fruit as affected by oxalic acid during storage at room temperature

► First report on oxalic acid suppressed and delayed expansin expression in mangoes. ► First report on oxalic acid decreased activities of pectolytic enzymes in mangoes. ► Further evidence supplied for the ability of oxalic acid to slow ripening in mangoes.
