Intracellular morphological processes of successive cytokinesis in cereal pollen mother cells during normal and
abnormal meiosis were studied. It was shown that the central spindle fiber system transforms into a phragmoplast at
telophase. A model of centrifugal movement of the phragmoplast as a modification of B-anaphase has been proposed.
Key words: cytoskeleton, plant cell division, meiotic mutants, phragmoplast, MTs
