Actually, no, you don't need a neuron to have a receptor site, although a cell membrane is probably one of the minimum requirements. I've found a bit of literature on it, and as you mentioned, dopamine (and the other catecholamines) seem to be part of the stress response in plants. Interesting, but not so much that I will dwell on it. Thanks for your response! Carol
