Abstract

  Plants produce a wide range of sugars that are involved in growth and developmental processes. To coordinate and integrate all these processes plants have developed specific mechanisms. A complex network of metabolic and hormone signaling pathways is present in plants that are intimately linked to diverse sugar responses. One of the mechanisms that has been found to modulate actively with other systems is the ‘sugar signaling mechanism’. In order to integrate these changes in the different processes and environmental conditions, plants have developed a mechanism to sense these ‘sugar signals’. While hormonal signals are generated at micro-molar concentrations, sugar signals are generated at milli-molar concentrations. The sugar signals modulate gene expression by acting on various kinases and phosphatases. Sugar signals are generated through metabolic processes such as relative concentrations of carbohydrates and other nutrients, through the action of specific enzymes or through various sensors and transporters that are present in the nucleus, cytosol or on the surface of certain organelles.After detection of sugars by sensors, the information is passed on through signal transduction and amplifying cascades, resulting in appropriate responses. Signaling cascades ultimately lead to gene regulation. Sugars regulate gene expression by translating nutrient status to modulate growth and development with available carbohydrate content.
