Accordingly, many studies have focused on the elasticity and plasticity of the cell wall as prerequisites for expansion during growth. With their specific evolutionary history, cell wall composition and environment, brown algae present a unique configuration offering a new perspective on the involvement of the cell wall-viewed as an inert material with yet intrinsic mechanical properties-in growth. In light of recent findings, we explore here how much of the functional relationship between cell wall chemistry and intrinsic mechanics on the one hand, and growth on the other hand, has been uncovered in brown algae.
