The study of wall biosynthesis is currently based on functional genomics. This strategy reaches its limits when the mutants are lethal or when one wishes to modulate in vivo in specific tissues or at specific times during growth the biosynthesis of cell wall polymers. At the same time, it is becoming more and more obvious that the establishment of the plant wall requires complex regulatory mechanisms which ensure the transport of Golgi vesicles containing polysaccharides towards particular areas of the wall. Several actors in these processes are beginning to emerge. We can cite, for example, variations in intracellular calcium, the dynamics of actin filaments or the interactions between membrane proteins involved in polarized growth. Until today, no study has clearly demonstrated the interactions that exist between these actors and the biosynthesis, then the establishment of the wall. Better understanding these mechanisms and even, ultimately, modulating them would allow, in addition to enriching our fundamental knowledge, significant agronomic advances. Modulating the quality of reserves or plant fibers through treatment and avoiding varietal selection would represent a major advance in agronomy.
