Preprophase band and division plane establishment

Abstract

To elucidate the regulatory mechanism of division plane establishment is necessary for understanding the development of multicellular organism. In plant cells, the division site, the cortical region where cell plate fuses with the parental cell walls, is pre-determined before nuclear division and the preprophase band marks the site in prophase. Here, I review the research on the development and function of preprophase band based on historical background of our research.
