Research progresses on the key enzymes involved in sucrose metabolism in maize

摘要

Sucrose, as the major product of photosynthesis, is a vital metabolite and signaling molecule in higher plants. Three enzymes are responsible for the synthesis, transport, and degradation of sucrose. In this article, the gene structure, expression and regulation, and the physiological functions of the key enzymes involved in sucrose metabolism in maize are reviewed, moreover, the existing problems of the sucrose metabolism research were discussed in detail, and we present our ideas for future research.
