Abstract
Expression of a variety of sink-related genes for the synthesis of storage compounds are up-regulated in response to increased levels of sugars, while expression of many genes involved in photosynthesis and the breakdown of storage compounds is repressed by sugars. Despite of extensive studies on sugar signaling in plants, only few transcription factors involved in the expression of sugar-inducible genes have been identified so far. A transgenic Arabidopsis thaliana line carrying luciferase gene under the control of a short sugar-inducible promoter derived from a sweet potato sporamin gene was used to screen for loss-of-function type as well as gain-of-function type mutants. These genetic screens resulted in the identification of novel transcription factors that are involved in the expression of at least a subset of sugar-inducible genes in Arabidopsis.
