The primary cell wall of dicotyledonous plants consists largely of cellulose and hemicelluloses embedded in a gel of pectins. Pectins are a heterogeneous group of polysaccharides that are synthesized in the Golgi apparatus and transported to the cell surface via secretory vesicles. Antibody studies have shown that there is a non-uniform and dynamic occurrence of different pectins across cell and tissue types, demonstrating the complexity of cell wall structure. How pectins are targeted to distinct cell wall domains, however, is unclear. To investigate the establishment of plasma membrane domains involved in pectin targeting, Arabidopsis thaliana mucilage secretory cells (MSCs) were used as a model.
Z-stacks were analyzed by creating 3D projections using Dragonfly.
