Plant Draft 2

Adventitious root growth is stimulated by a gaseous hormone called ethylene. While that may sound simple to orchestrate, scientists wondered how the plants decided what directions to grow the roots. In the paper, Control of Adventitious Root Architecture in Rice by Darkness, Light, and Gravity, Chen Lin and Margret Sauter describe their findings on the mechanisms behind the architecture of root growth in rice plants. They investigated this adventitious root growth in response to different light stimuli and different gravitational stimuli, and found some interesting results.
