The outside characteristics during fruit ripening are decrease of firmness,softening of textile.Firmness and textile are important indicators of fruit quality and criterion of ripening fruit,influenced the pre and post harvest handling methods,the life of shelf storage,and the flavor of fruits.Thus,the mechanism of cell wall hydrolases during fruit ripening and their relationship with the fruit softening will provide us a new way to control the fruit softening and to promote the crop breeding through gene improvement.This review focus on the research progresses of several main enzymes related to the fruit ripening,including polygalacturonases(PG),Pectinmethylesterases(PME),β-Galactosidases,endo-1,4-β-Glucanase(EGase),and XyloglucanEndo-transglycosylase(XET).
