The cell wall, a crucial cell compartment, is composed of a network of polysaccharides and proteins, providing structural support and protection from external stimuli. While the cell wall structure and biosynthesis have been extensively studied, very little is known about the transport of polysaccharides and other components into the developing cell wall. This review focuses on endomembrane trafficking pathways involved in cell wall deposition. Cellulose synthase complexes are assembled in the Golgi, and are transported in vesicles to the plasma membrane. Non-cellulosic polysaccharides are synthesized in the Golgi apparatus, whereas cellulose is produced by enzyme complexes at the plasma membrane. Polysaccharides and enzymes that are involved in cell wall modification and assembly are transported by distinct vesicle types to their destinations; however, the precise mechanisms involved in selection, sorting and delivery remain to be identified. The endomembrane system orchestrates the delivery of Golgi-derived and possibly endocytic vesicles carrying cell wall and cell membrane components to the newly-formed cell plate. However, the nature of these vesicles, their membrane compositions, and the timing of their delivery are largely unknown. Emerging technologies such as chemical genomics and proteomics are promising avenues to gain insight into the trafficking of cell wall components.

The plant Golgi apparatus and trans-Golgi network are major endomembrane trafficking hubs within the plant cell and are involved in a diverse and vital series of functions to maintain plant growth and development. Recently, a series of disparate technical approaches have been used to isolate and characterize components of these complex organelles by mass spectrometry in the model plant Arabidopsis thaliana. Collectively, these studies have increased the number of Golgi and vesicular localized proteins identified by mass spectrometry to nearly 500 proteins. We have sought to provide a brief overview of these technical approaches and bring the datasets together to examine how they can reveal insights into the secretory pathway.
