Previously non-described in literature abnormalities of phragmoplast formation in pollen mother cells of cereal haploids and allohaploids are reported.
These abnormal phenotypes reveal and illustrate some steps of the process of phragmoplast formation in dividing plant cell, indicate a special regulation of their start,
and confirm the information about the process obtained from other sources. The cytokinetic stage in plant cytoskeleton cycle is discussed.
Key words: cell plate, cytokinesis, plant cell division, plant cytoskeleton, meiosis, microtubules, phrag-moplast
