Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP₇ synthesis to control COP9 signalosome (CSN)–dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation response.
RCB was pleased to host Dr. Sylviane Pied, Attaché for Scientific Cooperation, and Dr. Meenakshi Singh, Scientific Coordinator, FII, from the Embassy of France, New Delhi. The discussions focused on exploring new avenues for research collaboration, followed by facility visits across key centres at RCB.
