Auxin is a mega-hormone that controls many aspects of cell growth and differentiation in plants.

Gravitropism, or how plants respond to lateral weight, seems to cause the traditional variation in growth form in many wildflowers, ranging from prostrate, to decumbent, to erect stems and branches.

You will use physiological experiments to explore how plants with different growth forms respond to auxin. You will attempt to determine whether transport or sensing varies between tall versus short plants, and with variable responses to lateral weight.
