The latent ability of plant microtubules to translocate or slide in the presence of motor protein was examined in a motility assay in vitro. Plant microtubules isolated from tobacco BY-2 cells moved over a glass surface covered with outer arm 21S dynein from flagella of sea urchin sperm with an average velocity of 3.7 μm s^<-1^gt;. This velocity was similar to that of microtubules isolated from bovine brain under the same conditions (average velocity, about 4.1 μm s^<-1^gt;). These results suggest that plant microtubules have an intrinsic ability to interact with and to be translocated by dynein. It is postulated that microtubule-based motor proteins, including dynein ATPase, are involved in the functioning of microtubules in plant cells.
