Abstract: Target of rapamycin (TOR) is a highly conserved serine/threonine-protein kinase among all eukaryotes. As a central regulator, TOR integrates nutrient, energy, growth factor and environmental signals to control cell proliferation, growth, and metabolism. With the establishment of TOR research systems in plants, tremendous progress has been made in, both conserved and unique functions of plant TOR have been uncovered in recent years. Here, we reviewed TOR complexes and the mechanisms of plant TOR integrating sugar, nitrogen, phosphate, sulfur, phytohormone and stress signals to orchestrate transcription, translation, metabolism, autophagy, and stress responses. We also highlight a few fundamental questions that will be of great interest to be resolved for fully revealing biofunctions of plant TOR.
