Coupe de racine de lin observée en microscopie confocale
Section of a flax root, labelled using the BLISS strategy, observed using a confocal microscope. This labelling strategy involves the incorporation of monolignols followed by the click ligation of fluorescent reporters. The natural fluorescence of the flax can be seen in blue, with the labelled monolignols in green and red. This method enables research scientists to study lignin formation. Lignin is one of the main components of wood. This biomolecule is present in all vascular plants, ligneous and herbaceous, making them rigid and water resistant.
