Plant hormones are a collective term for a series of signaling molecules that regulate plant growth. The simplest structure of plant hormones is ethylene. Ethylene is involved in regulating many plant physiological activities, including germination, results, and so on. At the same time, ethylene is also an important signaling molecule for plant stress. 1- Aminocyclopropane-1-carboxylic acid or ACC is an important precursor for the biosynthesis of ethylene in plants. It also plays an important role in the transportation of ethylene by plants. We are currently using classic organic chemistry methodologies from readily available materials to synthesize 2- halo-ACC analogues that will be investigated for phenotypic responses in the plant model Arabidopsis thaliana. The long-term goal of this work is to develop a practical route for the radiochemical synthesis of [18F]-ACC as a novel plant hormonal positron emission topography [PET] imaging agent. Furthermore, its subsequent metabolism to [18F]-ethylene by ACC oxidase is an interesting proposition and has the potential to become a new radioanalytical method for rapid radiometabolomics and modeling in plants. Our hypothesis is that [18F]-ACC and [18F]-ethylene will be important plant imaging agent to understand how resource allocation for plant growth and development is affected by environmental stress.
