Plant vibration, from wind flutter to phenotyping

Emmanuel de Langre (École polytechnique, Palaiseau, France)

Plants are often very flexible objects. This results in motion under stimuli such as wind or currents, but also hosts such as insects. Motion are known to influence plant development by thigmomorphogenesis. I will review methodologies and results from the past ten years, aimed at quantifying and understanding the vibration of plants, or parts of plants, from Arabidopsis Thaliana to large trees. I will focus on experimental techniques indoor and outdoor, on simple models of motions, and the role of the plant architecture. The recent application to high throughput plant phenotyping by vibrations will also be presented.
