Soluble sugars, such as glucose and sucrose, play an important role in the cycle of plant life. They not only provide energy and mid-metabolites, but also act as signals, regulating the growth and development of plant. When regulating the plant, sugars with other signals such as hormone constitute complex transduction web. In this paper, we illuminate the regulation of soluble sugars in the development and growth of plant, and the interaction of soluble sugars and phytohormones, and environment factors.
