Very important advances have been made since the publication of a major review of this subject by Shafizadeh and McGinnis (1971), but we seem no nearer to consensus (see, for example, St?ckmann, 1972; Atalla and Nagel, 1974; Preston, 1974; Palma .., 1976;

Synthesis occurs in the context of a directed membrane flow throughout the endomembrane system (Mom? et al, 1971; Whaley .., 1971; Northcote, 1974) —from the nuclear envelope to the endoplasmic reticulum to the Golgi apparatus to the plasma membrane—and is a

The long list of callose deposition sites includes fungal and algal cell walls, pollen tube walls and as plugs in pollen tubes, sieve cells, guard-cell walls

Microfibrils have been observed by electron microscopy of fungal cell walls by use of different techniques: shadow-casting, heavy-metal replicas, negative staining, and oblique and ta

But, depending on the source, it is also associated to varying degrees with other noncellulosic components that necessitate purification by che

Studies on primer requirements for synthesis of other polymers, e.g., .-glucans, DNA, glycoproteins, have been extraordinarily informative in elucidating mechanisms of synthesis and regulation and in understanding their biolog
