| Abstract: | Plant stems and roots orient themselves with respect to directional illumination and gravity by differential growth on either side of the organ. A model formulated in the 1930s proposed that tropic growth curvature arose from growth hormone redistribution. Studies with Arabidopsis are beginning to reveal the mechanism. |
