Abstract: The form and structure of starch and its biosythesis pathway involving the key enzymes and the method of metabolism regulation were summarized in this paper, the relationship between Waxy property of endosperm and starch biosythesis was stated as well. The structure and mutants of Waxy gene along with mechanisms of Waxy trait emerging in several crops (wheat, barley, rice, sorghum, maize, common millet, Job’s tears, ect.) were summed up in a brief way. An outlook of Waxy application in agricultural production and breeding were also discussed.
