Review on maize endosperm starch synthesis

doi:10.11924/j.issn.1000-6850.2014-1316

Abstract

Abstract: The utilization of maize starch in food industry was determined by its physicochemical characteristics and starch structure. Regulating the starch quality needs to understand the starch synthetic route. In recent years, studies showed that the starch synthesis was controlled by the interaction of the isozymes of ADP-glucose pyrophosphorylase (AGP), starch synthase (SS), starch branching enzyme (SBE) and starch debranching enzyme (DBE). Due to the different isozymes activities and the mutation of coding gene, different starch structures were formed and different industrial applications were produced. In the present paper, the properties of physiology and biochemistry, molecular biology and gene expression of those enzymes were summarized, the relative ways of starch quality improvement were proposed and the possible development direction was discussed.
