Methylation is a frequent modification of glycans and polysaccharides. This process relies on the transport of cytosolic S-adenosyl-l-methionine (SAM) into the Golgi lumen. This work identifies Golgi-localized major facilitator superfamily transporter members as putative SAM transporters in plants and reveals their importance for polysaccharide methylation and maintenance of the properties of cell walls.
