Cell Wall Layers

Caption

The protein CSI1 and the alternating angle of the many layers that make up a cell's wall, creating a herringbone pattern (left), are critical for cell growth. The cell wall layers of a mutant plant without the protein CSI1 are all oriented in the same direction (right), and the mutant's growth is restricted.
