Figure 7: Hypothetical model on the mechanism of phragmoplast expansion.
From: Mechanism of microtubule array expansion in the cytokinetic phragmoplast
(a) Microtubule proliferation cycles at the leading edge of the phragmoplast. Top of the drawing is the direction of phragmoplast expansion. (b) Role of microtubule flow in phragmoplast expansion. Without microtubule movement, microtubules converge towards the cell plate, and phragmoplast length between distal regions decreases during expansion (left). With microtubule movement away from the cell plate, phragmoplast length is maintained (right).
