K. Scott. 1976. Cellulosic microfibrils: nascent stages of synthesis
in a higher plant cell. Science 194:949-951.
Freeze-fracturing of untreated plasma membrane
and inner wall surfaces of stelar tissue in corn roots demonstrated
the association of globular complexes with the ends of nascent
microfibrils. It is proposed that the granule complexes associated
with the outer leaflet of the plasma membrane coordinate the assembly
of the cellulosic microfibrils.
