A central unifying theme of my research has been to understand the processes of plant morphogenesis regulated by unique, non-traditional plant growth regulators such as melatonin and serotonin, the indoleamine, which influence almost every aspect of plant life from morphogenesis to reproduction. Indoleamines also possess exceptional stress mitigation attributes enabling plants to redirect growth in response to environmental stresses. We demonstrated that such modulations in plant development and stress mitigation responses may occur via a symphony of actions of molecules in the entire indoleamine pathway rather than a specific molecule. Real-time tracking of melatonin and serotonin using Quantum Dot nanoparticles showed that plants have a mechanism to utilize these molecules as antioxidants in coping with stress. We continue to research the biochemical and molecular mechanisms of diverse functions of indoleamines, as well as, their interactions with other signaling networks in plant adaptations to biotic and abiotic stresses.
