The cell membrane, being exposed to the outside environment, is an important site of cell-cell communication. As such, a large variety of protein receptors and identification proteins, such as antigens, are present on the surface of the membrane.
Concerning to the receptor for chitin oligosaccharide elicitor, we previously identified a high-affinity binding protein for this elicitor in the plasma membrane of rice cells by affinity labeling (7). Similar binding proteins were also detected in various plant cells that could respond to the elicitor (8, 9).
