Measuring external primary cell wall elasticity of seedling roots using atomic force microscopy
Résumé
Stiffness plays a central action in plant cell extension. Here, we present a protocol to detect changes in stiffness on the external epidermal cell wall of living plant roots using atomic force microscopy (AFM). We provide generalized instructions for collecting force-distance curves and analysis of stiffness using contact-based mechanical model. With this protocol, and some initial training in AFM, a user is able to perform indentation experiments on 4-and 5-day-old Arabidopsis thaliana and determine stiffness properties.
