Until recently, two distinct types of cytokinesis were thought to be responsible for the division of plant and animal cells. Plant cells divide through the formation of a membrane plate between the daughter cells, while animal cells divide by the constriction of a cortical actin-based ring around the cell. However, accumulating evidence suggests that the two mechanisms may have more in common than previously thought. In this review we will focus on recent developments that raise the possibility of unexpected similarities between the final steps in cytokinesis in animal and plant cells.
