This $714,689 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) funds collaborative research at the University of California, Davis to decipher the molecular mechanisms of hormone-like function of terpenoids in plants. The research will characterize signaling pathways involved in plant perception of volatile organic compounds, particularly terpenoids, and their role in plant growth, development, and inter-organism interactions. It will investigate the hypothesis that a karrikin-like signaling pathway mediated by the karrikin-insensitive receptor PHKAI2IA regulates terpene-dependent stigma development in petunia flowers. The work will employ genetics, molecular biology, biochemistry, metabolic profiling, structural and cell biology to identify targets of the new KAI2IA-dependent volatile sesquiterpene signaling pathway in plants, perform structure-function analysis of the PHKAI2IA receptor, and determine if the pathway operates via the MAX2 ubiquitin ligase essential for karrikin signaling. Insights gained will further understanding of plant olfaction, volatile perception and signaling mechanisms.
