Studies involving the habituation of plant cell cultures to cellulose biosynthesis inhibitors have achieved significant progress as regards understanding the structural plasticity of cell walls. However, since habituation studies have typically used high concentrations of inhibitors and long-term
The structure of the arabinogalactan obtained from the buffer-homogenate of Zea mays L. (hybrid B73 x Mo17) shoots has been studied. The purified polysaccharide was investigated by methylation analysis before and after controlled acid hydrolysis. Arabinogalactan-1 consists of arabinose, galactose,
Incubation of purified cell wall fragments from corn (Zea mays) coleoptiles results in solubilization of some of the wall dry matter. The portion of the weight loss due to enzymatic autolysis is due mainly to solubilization of a glucan and, to a small extent, to liberation of free glucose. No other
The water-insoluble fraction, obtained after successive treatment of an insoluble fraction of a buffer-homogenate of Zea mays L. hybrid B73 x Mo 17 shoots with 3 molar LiCl and hot water, was treated with alpha-amylase to remove starch. This fraction has been subjected to sugar composition analysis
Cell walls of Zea mays (cv L.G.11) seedlings labeled with (14)C were treated with alpha-amylase from Bacillus subtilis to remove starch and mixed linkage glucans. These walls released arabinose, xylose, galactose, and galacturonic acid in addition to glucose when they were allowed to autolyze.
Two monoclonal antibodies (McAbs) generated against rhamnogalacturonan I and characterized as specific for a terminal [alpha]-(1->2)-linked fucosyl-containing epitope (CCRC-M1) and for an arabinosylated [beta]-(1,6)-galactan epitope (CCRC-M7) were used in immunogold experiments to determine the
Brefeldin A (BFA) inhibits exocytosis but allows endocytosis, making it a valuable agent to identify molecules that recycle at cell peripheries. In plants, formation of large intracellular compartments in response to BFA treatment is a unique feature of some, but not all, cells. Here, we have
