Evaluation of microtubule bundling in vivo. (A) Representative confocal laser scanning microscopy images of yellow fluorescent protein (YFP)-tubulin-labeled microtubules in tobacco BY-2 cells. Cortical microtubules at the G1 phase (left) and highly bundled cortical microtubules in the preprophase band (right) are shown. Scale bar indicates 2 μm. (B) Skewness of the intensity distribution. (C) CV of the intensity distribution. Significance was tested using the Mann–Whitney U-test. N = 24.
