title: Cell biology: up against the wall.
abstract: Lignin is deposited in precise patterns in some cell types. Two recent papers provide insights into how this is achieved in the Casparian strip of the root endodermis where a discrete band of lignin is crucial to regulating the passage of water and solutes.
