«Although polarization and asymmetric cell division of zygotes to form the body axis is a common phenomena found in algae, mosses, and flowering plants, the origin of cell polarity and
how asymmetric cell division occurs have remained a mystery up to now,» says Dr. Minako Ueda, a lecturer at ITbM, Nagoya University and a leader of this research.
The group succeeded in visualizing for the first time,
how the cytoskeleton of plant egg
cells is disassembled after fertilization and then reorganized to create a polarity in the
cell that eventually leads to
asymmetric cell division.
