Abstract
Plant cells divide by formation of the cell plate. The cell plate is formed by the cytokinetic apparatus phragmoplast. The phragmoplast is a cytoskeleton-membrane complex, which contains many microtubules. Although expansion of the phragmoplast drives growth of the cell plate towards the plasma membrane, the mechanism is unclear. The author’s group demonstrated microtubule organization and dynamics in the phragmoplast, and proposed the mechanism how the phragmoplast expands. I will describe the mechanism of phragmoplast expansion in this review.
