✦ Synopsis
In an attempt to provide a unified hypothesis to account for the various aspects of oriented cellulose fibril synthesis it is proposed that plasmalemma located cellulose synthetase enzyme complexes are free to move in the plane of the membrane. Their directed movement may be produced by a component which is associated with the synthetase complex and which also interacts with cytoplasmic microtubules to generate a sliding force which moves the entire complex through the membrane utilizing the microtubule as a rigid guiding track and thus laying down, in the wake of the complex, cellulose fibrils whose orientation mirrors that of the microtubules.
