Deciphering the impact of glucose signaling on fruit quality

Abstract

Glucose is a preferred source of carbon and energy for plants. In addition to metabolic functions, glucose is a well-known signaling molecule that regulates plant growth and development through multiple pathways. In this review, the mechanisms by which glucose signaling regulates the accumulation of sugars and organic acids, as well as the ripening of fleshy fruit, are examined. An analysis of these complex molecular networks demonstrates the impact of glucose signal perception on fruit quality.
