Outline of Final Research Achievements |
Plants evolved by a primitive unicellular animals acquiring chloroplast. However, cytokinesis, which is one of mechanisms to proliferate cells, is greatly different between animals and plants. When animals and also fungi divide their cells, plasma membranes that envelop cells are invaded from the outside to the inside, and finally the cell membranes break down. It is known that this invagination involves a circular molecular apparatus called contractile ring. On the other hand, in plants, a molecular apparatus called cell plates are expanded from the inside to the outside of the cell. Here, genes involved in cytokinesis of algae, which are primitive plants, were compared with animals and plants. As a result, the evolutionary process of one of animal and fungal type cytokinetic apparatus called septin was revealed.
