The survival of our civilization is entirely dependent on plants. Nevertheless, many relevant aspects of plant biology remain unknown. One of the most intriguing is the biological process of plant growth and morphogenesis. The conundrum of plant growth lies in the rigid polysaccharide network surrounding every plant cell: the cell wall (Caffall and Mohnen, 2009). It determines cellular shapes, tissue biomechanics, and the overall morphology of the organism (Höfte and Voxeur, 2017). Ultimately the growth process in plants depends on the cell wall expansion allowing cell enlargement..
