Flowering plants produce ethylene from a molecule called 1-amino-cyclopropane-1-carboxylic acid (ACC). Given that ACC is much easier to work with than ethylene gas, scientists often treat plants with ACC in order to induce ethylene responses. However, recent evidence tells us that ACC can unexpectedly trigger responses in plants that are distinct from those induced by ethylene. This raises the interesting possibility that ACC itself is a signal in plants with ramifications for the use of ACC as a substitute for ethylene. Evolutionarily, we find that ACC may have served as a signal prior to acquiring its role as the ethylene precursor in seed plants. This seminar will present some of the supporting evidence we found in the liverwort Marchantia polymorpha and the small flowering plant Arabidopsis thaliana, in the context of the emerging evolutionary history of ethylene as a plant hormone. ------------------------------------------------------- Our next meeting will be on Tuesday, September 5.
