Figure 2.

Serial images of mechano-avoidance response of photo-relocated chloroplasts. Mechanical stimulation was applied vertically with the flank of a capillary for 1 min. A, Dark control; B through D, cells were continuously pre-irradiated with polarized light for 3 h before mechanical stimulation and the light was kept on throughout the experiments. B, LRL (0.44 W m⁻²); C, LBL (0.79 W m⁻²); D, HBL (about 10 W m⁻²). Bar, 20 μm.
