Lignification is arguably one of the most important biochemical processes that evolved in nature.1,2,8 In this way, the vast majority of land-based multicellular plants developed a system whereby some of their cells (actually cell wall types) evolved to facilitate conduction of water and nutrients in their various forms of vascular apparatus (see arrowheads, Figures 2 (a)–2 (f)). Finding bio-friendly ways of removing it without resorting to chemicals like dioxin is a challenge for the future. ‘protoplasts are needed for the cell walls to continue to thicken and lignify’.
