Abstract: | The occurrence, localization, and properties of xyloglucan in the cell walls of growing regions of Pinus pinaster hypocotyls have been studied. Xyloglucan was released from the cell wall with alkali solutions, the concentration increasing from 4 through 35%; KOH. In vitro experiments showed that xyloglucan and cellulose can interact, forming a macromolecular complex. Electron microscope observations showed that the cell wall material extracted with 35%; KOH, which contained some amount of xyloglucan, was enough to cover and join the cellulose microfibrils. |
