Phragmoplast Dynamics Plant Cell Division

An Arabidopsis root expressing Microtubule-Binding-Domain GFP under the control of the 35S promoter. Near the top of the image is a mitotic spindle that transforms into a phragmoplast, with a clearly visible midzone. As the phragmoplast matures, the microtubules are disassembled near its center and reassembled at its phragmoplast edge, leading to the formation of a ring phragmoplast, only two edges of which are visible in this focal plane.
