Phototropic Equilibrium in Phycomyces
Science, 1959When illuminated by two light sources, the positively phototropic sporangiophores of Phycomyces blakesleeanus come into a state of phototropic equilibrium. In this state, the sporangiophores assume an orientation determined by the light fluxes falling upon opposite sides of their light-sensitive zones. Under certain

Certain growing plant organs bend towards the light when exposed to asymmetric illumination. The phenomenology of this - positive-phototropism in lower plants will be our main topic. The implicit aim, however, is an analysis leading towards the molecular understanding of the reaction chain.

Orientation in space: phototropism
1988Plants are in the main non-motile organisms. Moreover, the raw materials necessary for their growth and development are present in the environment in relatively dilute amounts. Therefore, to maximize their uptake of nutrient and energy, plants must continually monitor and adjust the orientations of their various organs.

Roles of Hormones in Phototropism
1985Because sunlight is the foremost environmental requirement of higher plants, processes which help seedling shoots emerge from the soil into the air, and which direct further development so as to optimize the intensity of light received by the leaves, are critical for plant survival.
