French scientists unravel lignin biosynthesis [Registered]

A study published in The Plant Cell (2011, March) furthers our understanding of lignin formation in the model plant Arabidopsis. Two laccase genes are shown to play a major role in lignin deposition. Lignin is the durable biopolymer acting as the glue that holds the plant cell wall together. It imparts tremendous mechanical strength to the plant. Present in all land plants except mosses, lignin performs three important functions: it allows plants to grow upright as they compete for sunlight, it facilitates the upward movement of water and minerals through the plant’s vascular tissue, and it protects plants from pathogens…
