Arabidopsis glucose-signaling networks. Glucose is generated from the photosynthetic or storage source and transported as sucrose or glucose to the sink tissues and organs to promote cell proliferation, elongation, expansion, and to maintain energy and metabolic homeostasis. The regulatory mechanisms and functions of three master regulators, HXK1, KIN10/11 and TOR, modulated by glucose signals are shown. The glucose signaling networks are intertwined with the signaling pathways controlled by environmental light, nutrients, stresses and microbes, as well as internal hormones, peptides and clock. Red stars mark the action sites of glucose signaling. Glc, glucose; HXK, hexokinase; HKLs, hexokinase-like; KIN, Arabidopsis protein kinase; QC, quiescent center; TOR, target of rapamycin.
