A microtubule that showed backward sliding in the anterior region in response to imposed bending in the posterior region. The sequential pictures of this movie are shown in Fig. 7A. The number on the upper left corner of this movie indicates time (seconds) after the beginning of this movie. Backward sliding is induced by imposed bending that begins at 20.1 s. This time point is redefined as “0 s” in Fig. 7A. Scale bar: 10 µm.
