Sucrose is a molecule that is synthesized only by oxygenic photosynthetic organisms. In plants, sucrose is synthesized in source tissues and then can be transported to sink tissues, where it is utilized or stored. Interestingly, sucrose is both a metabolite and a signaling molecule. Manipulating the rate of the synthesis, transport or degradation of sucrose affects plant growth, development and physiology. Altered sucrose levels changes the quantity of sucrose derived metabolites and sucrose-specific signaling. In this paper, these changes are summarized. Better understanding of sucrose metabolism and sucrose sensing systems in plants will lead to opportunities to adapt plant metabolism and growth.
蔗糖是一种仅由产氧光合作用生物合成的分子。在植物中，蔗糖在源组织中合成，然后可以运输到汇组织，在那里被利用或储存。有趣的是，蔗糖既是代谢物又是信号分子。操纵蔗糖的合成、运输或降解速度会影响植物的生长、发育和生理。蔗糖水平的变化改变了蔗糖衍生代谢物的数量和蔗糖特异性信号。本文总结了这些变化。更好地了解植物中的蔗糖代谢和蔗糖感应系统将为适应植物代谢和生长提供机会。
