Extreme cytokinesis phenomenon in the phenotype of meiotic mutation pam of Zea mays

Our study of cytological phenotype of meiotic mutation pam resulted in detecting a failure of cytokinesis in mutant pollen mother cells in the form of a block of fusion of membrane vesicles of the cell plate, and an impossibility of formation of daughter cell membranes. The mutation does not disturb the division spindle structure and function. Asynchrony of meiosis in pam is the result of arrest of pollen mother cells at metaphase 1 and metaphase 2.
