In plants, polarization of the entire organism depends on every single cell being polarized. Cell division, however, disrupts polarization. How polarity is reestablished was unknown – until now. Researchers at the Institute of Science and Technology Austria (IST Austria) and Faculty of Science, Prague, have solved one piece of the puzzle: They found that plant cells inherit the knowledge of where is up and where’s down from their mother cell. Study published in Nature Plants.
