The biochemistry of plant cell-walls is still at the stage of identifying and elucidating the covalent structures of the macromolecular components of the primary cell-wall. The secondary, tertiary, and quarternary structures of the polysaccharides therein have received only scant attention.29-32 The ultrastructural distribution of polymers within the wall, the integration of newly synthesized macromolecules into the wall, and...

BSs protected cereal leaf cells from heat shock or saline stress. Leaf pre treatment with BSs decreased cell ultrastructure degradation from heat shock and high salt conditions. BSs increased HSG formation which is supposed to protect preformed mRNA in plant cells during heating. BSs enhanced heat shook resistance of the leaf protein-synthesizing system. The effect of BSs on RNA and protein synthesis was shown earlier (14). We observed protein synthesis activation in wheat leaves by BSs in normal and under stress conditions. Two-dimensional SDS-FAAGE of dS-methionine labeled proteins demonstrated BS-induced changes in the set of polypeptides synthesized in leaves and in the rate of their synthesis.

It is known that hardy plant cells exhibit increased permeability to water (12,81,82,83). In some cases, cytological and ultrastructural differences in chloroplasts of hardy and nonhardy leaves have been reported (15,84,85). These observations require interpretation. 

Although all eukaryotic cells have much in common, the ultrastructure of a plant cell differs firom that of the typical mammalian cell in three major ways. First, all living plant cells contain plastids. Second, the plasma membrane of plant cells is shielded by the cellulosic cell wall, preventing lysis in the naturally hypotonic environment but making preparation of cell fractions more difficult. Finally, the nucleus, cytosol, and organelles are pressed against the cell wall by the tonoplast, the membrane of the large, central vacuole that can occupy 80% or more of the cell s volume. 

The natural fibers of cotton and wood are the most important commercial sources of cellulose. Thus, knowledge of their structure is essential to any discussion of its enzymatic degradation. Several excellent reviews of cellulose structure have been published recently those on cotton by Hamby (22) and Warwicker et al. (76), and on wood in the volumes edited by Zimmerman (79) and C6t6 (7), as well as the discussions of the ultrastructure of plant Cell walls by Miihlethaler (47) and Rollins (59) make more than a general summary here unnecessary.
