Listening to corn stalks to stop wind-induced failure

Douglas Cook at New York University and colleagues from the University of Nebraska are using special microphones to listen to corn plants in order to determine what leads to wind-induced corn stalk failure. It turns out, the sounds stalks make just before failure are very similar to the sounds made when breaking. "We now think that plant growth involves millions of tiny breakage events, and that these breakage events trigger the plant to rush to 'repair' the broken regions. By continuously breaking and repairing, the plant is able to grow taller and taller," says Cook. It's an idea that mimics the science behind how human muslces are built: Muscles are strengthened when tiny microtears are repaired after lifting weights. Although most of the work is still in the early stages, this marriage of mechanical engineering and plant science and the information gathered so far can help plant breeders design optimal, strong plants. | READ MORE
