Plants are endowed with mechanosensitive channels

Caption

Plants are endowed with mechanosensitive channels such as MSL that transduce mechanical oscillations into electrical signals. In static condition, the cell membrane of the model plant Arabidopsis thaliana is hardly solicited, and the MSL10 'switch' shows little activity (left-hand side). When the membrane is subjected to an oscillatory pressure mimicking the effect of the wind, the switch becomes more active (oscillation, right-hand side). This is shown schematically on the diagram in the bottom right of the figure.
