Sucrose is an important energy carrier in the process of plant growth and development, and it is also a kind of important raw material in food processing. In recent years, we had made many research results in the sucrose metabolism physiology, biochemistry, molecular biology and other fields. This Paper introduces some recent research progress of sucrose synthesis, transport and degradation metabolic processes of higher plants, and might be a good help to improve the sugar content of plants in using bio-engineering methods in the future.
