Cell wall

The plant cell wall is a complex matrix of linked polysaccharides such as cellulose and pectin, forming a thick semi-permeable rigid barrier outside the plasma membrane. It physically protects and constrains the cell, and its exact composition is highly variable depending on the species.

    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.

    The lipid biopolymer suberin is an integral component of the root diffusion barrier, yet its deposition changes dynamically in response to both developmental and physiological cues. A new study identified GELP family proteins as strong candidates for suberin polymerases and degradases acting in suberin remodelling.
