Sucrose Metabolism and Regulation in Sugarcane

Photo assimilates store in the form of sucrose in the stalks of sugarcane that provide 70% of world sugar. To meet the growing demand for sugar, it needs to increase the sugar yield. Sucrose accumulation is a complex physiological process controlled by network genes. This review summarized the development in the molecular regulation mechanism of sucrose accumulation in sugarcane. The molecular involving in source-sink communication, sucrose metabolism and storage were discussed. Although the sugar yield in sugarcane has not been increased by genetically modification, further researches to clarify the regulatory networks of sucrose accumulation will be helpful to breed high sugar content sugarcane.
