Abstract
The experiments we are about to describe started1 as a new approach to an old problem—the mechanism of gravity perception in plants. All higher plants are sensitive to gravity; indeed the oriented growth of organs such as roots, shoots, and leaves is governed primarily by it. If a plant organ is by any means displaced from its normal direction of growth, certain regions of the organ sensitive to gravity will perceive the change and then, by a hormone-mediated mechanism, will induce one side of the organ to grow faster than the other, producing a curvature tending to restore the normal orientation to the growing part of the organ. The sensitive areas are usually the extreme apical regions.
