Epidermal trichomes function as mechanosensors, but how trichome-less plants perceive mechanical forces remains unclear. Touching epidermal pavement cells with micro-cantilevers, we discovered distinct cytosolic calcium waves upon application and release of small forces. Thus, not only do plants perceive forces independently of trichomes, they may also distinguish touch from letting go.
