| Outline of Final Research Achievements |
The function of the plant cell wall in information-processing largely depend on its structural features. The most widely accepted structural model for the plant cell wall was “tethered-network model” which holds that cellulose microfibrils are tethered by xyloglucan or other matrix polysaccharides to form skeletal network of cellulose. But this model has been challenged by recent reports. In the present we found that certain cell wall enzyme can mediate splitting and reconnection of cellulose molecules by transglucosylation reaction, and named this enzyme activity as Cellulose Endo Transglucosylase (CET). On the basis of this new finding we propose a new structural model for the plant cell wall, a model in which cellulose microfibrils are directly tethered via a covalent bonding between cellulose microfibrils.
