Good vibrations. Some analytical advances on leaf vibration analysis

Résumé

A significant part of the mechanical stimulation from the environment involves vibrations in plant tissues such as leaves. However, little is known about the mechanoperception of these vibrations because of experimental difficulties in quantifying tissue motions. Here we report ex- perimental and analytical advances developed to explore plant leaf vibrations from Hz to kHz. We developed a finite element model describing leaf vibrations of Arabidopsis thaliana. The model has been validated by 3D laser measurement. Since 3D laser measurement systems are not eas- ily accessible, we also developed an alternative advanced image analysis method exploiting high speed cameras allowing the spatio-temporal quantification of vibrations. These experimental and conceptual tools are valuable aids to find morphological parameters favoring mechanoperception at specific frequencies and allow us to investigate spatially molecular mechanisms involved in mechanoperception of vibrations at sub leaf scale.
