Cellulose microfibrils: visualization of biosynthetic and orienting complexes in association with the plasma membrane

R M Brown Jr et al. Proc Natl Acad Sci U S A. 1976 Jan.

Abstract

Cellulose microfibril biosynthesis, assembly, and orientation in the unicellular green alga, Oocystis, is visualized in association with a linear enzyme complex embedded in the B face of the plasma membrane. Granule bands of the A face and complementary ridges of the B face are postulated to assist in the orientation of recently synthesized microfibrils. A model for microfibril synthesis and orientation is proposed and correlated with current hypotheses regarding cellulose biosynthesis in higher plants.
