The aim of this project is to consolidate a Max Planck Institute/Universidade de São Paulo collaboration to investigate the interplay between the metabolism and the circadian clock in plants. The research group in the Max Planck Institute of Molecular Plant Physiology (Germany) has a long history investigating several aspects of the regulation and integration of the plant metabolism. The research group in São Paulo has expertise in the plant circadian clock and its regulation by sugars. The circadian clock is known for regulating several metabolic pathways, while sucrose has been recently described to regulate the circadian clock. The circadian clock is also important for starch metabolism, as starch is synthesized and degraded following the photoperiod the plant is growing. In this ongoing collaboration, both groups have the intention to further detail how the metabolism and the circadian clock regulate each other, especially on sugarcane, a strategic bioenergy crop that accumulates sucrose in its culm.
