Undoubtedly, the function of the plant cell wall in the control of cell growth far exceeds its mechanical role. The plant's monitoring of cell wall function and integrity comprises a central checkpoint to integrate cues for survival and division, expansion and differentiation, as well as fluctuations in the biotic and abiotic environment (Somerville et al., Science 306:2206-2211, 2004). With their biochemical nature yet unknown, the identification of molecular constituents of cell wall performance, and integrity control initially depends on a combination of genetic and physiological approaches.
