Organisms sense and respond to environmental and developmental signals to drive adaptive responses(Kefauver et al.,2020;Yu et al.,2024).These stimuli can be mainly divided into physical and chemical stimuli,and the physical stimuli include light,temperature,sound,vibration,pressure,stretch,shear stress,osmotic stress,and substrate *** of these physical stimuli trigger physical forces and alter membrane tension,which in turn activates mechanosensitive channels(MsCs)and converts the mechanical cues into biochemical signals.
