Plant hormones interact with genetic and environmental factors             to regulate every aspect of plant growth, development and physiology.           Despite intense effort, mechanisms of plant hormone actions are not             well defined.  This project will examine the effects of plant                   hormones on plant plasma membrane ion channels in an effort to define           their mode of action.  Patch voltage clamp, magnetic resonance, and             fluorescence techniques will be used to determine if models of                  intracellular control based on calcium entry or internal calcium                release can account for the diverse effects of plant hormones.  In              particular, suspension cell culture-derived protoplasts and isolated            guard cell protoplasts of Vicia faba will be examined to identify ion           channels, to measure channel selectivity and voltage dependence, and            to test whether voltage changes may arise from the action of                    electrogenic proton pumps, channel activation, or a combination of              pumps and channels.  A specific model of stimulus-linked changes in             guard cell volume will be tested.                                                    The results of these studies should contribute substantially to            our understanding of basic mechanisms of action of plant hormones.
