Abstract

Freeze-fracture of rapidly frozen, untreated plant cells reveals terminal complexes on E-fracture faces and intramembrane particle rosettes on P-fracture faces . Terminal complexes and rosettes are associated with the ends of individual microfibril impressions on the plasma membrane . In addition, terminal complexes and rosettes are associated with the impressions of new orientations ofmicrofibrils . These structures are sparse within pit fields where few microfibril impressions are observed, but are abundant over adjacent impressions ofmicrofibrils . It is proposed that intramembrane rosettes function in association with terminal complexes to synthesize microfibrils. The presence of a cellulosic microfibril system in Zea mays root segments is confirmed by degradation experiments with Trichoderma cellulase .
