Plant Physiology Online: Phototropism: From Photoperception to Auxin-Dependent Changes ... - 0 views

  • Phototropism—the directional curvature of organs in response to lateral differences in light intensity and/or quality—represents one of the most rapid and visually obvious responses of plants to changes in their light environment
  • In nature, stem phototropism likely provides plants with an effective means for maximizing photosynthetic light
  • signal-response components mediating the basal UV-A/blue light-induced phototropic response in seedlings.

  • Phototropism has been the subject of study for more than 120 years
  • Photoreceptor molecules, the phototropins, capable of perceiving directional UV-A/blue light cues have been identified and characterized.
