Research Abstract |
Cytoplasmic streaming is defined as an extensive intracellular motility in plants, but the mechanism remains unclear. This work demonstrates that endoplasmic reticulum (ER) dynamics is driven primarily by the ER-associated myosin XI-K, a member of a plant-specific myosin class XI. Furthermore, this work shows that the myosin XI involves in the organization of the actin filament bundles. These results suggest a model whereby dynamic three-way interactions between ER, F-actin, and myosins determine the architecture and movement patterns of the ER strands, and cause cytosol hauling traditionally defined as cytoplasmic streaming.
