News Finding: Researchers at Penn State have identified the major steps in the process used by plant cells to create cellulose:  CSI1 interacts with the exocyst complex, which is involved in transporting materials to the plasma membrane &amp; protein called PATROL1 #plantsci 
Paper Finding: Therefore, delivery of CSCs to discrete sites at the plasma membrane is critical for cellulose synthesis.

Paper Context: Therefore, delivery of CSCs to discrete sites at the plasma membrane is critical for cellulose synthesis. We propose that CSI1 plays a role in marking the docking site, which allows CSCs-containing vesicles access to the plasma membrane through its interaction with microtubules. PATROL1 assists in exocytosis by its interaction with multiple components, including CSI1, CSCs, and exocyst subunits.
