Proceedings of the National Academy of Sciences of the United States of America, 2021 Suberin is a hydrophobic biopolymer that can be deposited at the periphery of cells, forming protective barriers against biotic and abiotic stress. In roots, suberin forms lamellae at the periphery of endodermal cells where it plays crucial roles in the ...

Hydroxycinnamates in suberin formation
Phytochemistry Reviews, 2009Hydroxycinnamates are found associated with suberin in several forms: covalently linked to the aliphatic suberin; in the residue after suberin-removal; and in the non-polar extractives of suberized tissues in the form of alkyl ferulates. Suberin-associated hydroxycinnamates have been found mainly as ferulic acid-derivatives, sometimes as feruloylamides

Precursor biosynthesis regulation of lignin, suberin and cutin
Protoplasma, 2021The extracellular matrix of plants can contain the hydrophobic biopolymers lignin, suberin and/or cutin, which provide mechanical strength and limit water loss and pathogen invasion. Due to their remarkable chemical resistance, these polymers have a high potential in various biotechnological applications and can replace petrol-based resources, for ...

This chapter examines lignin, which has proven to be a useful chemical biomarker for tracing vascular-plant inputs to aquatic systems. Cellulose, hemicellulose, and lignin generally make up >75% of the biomass of woody plant materials. Lignins are a group of macromolecular heteropolymers found in the cell wall of vascular plants that are made up of ...

American Potato Journal, 1991
Several fluorescent staining procedures to detect suberin in normal periderm of potato were assessed. Among the stains tested, treatment with the alkaloid fluorochrome berberine followed by counterstaining with crystal violet appears to be the most sensitive combination.

Suberin degradation by Rosellinia desmazieresii
European Journal of Forest Pathology, 1994AbstractIn culture, Rosellinia desmazieresii, the agent of a ring‐dying disease in Salix repens, which can penetrate intact periderm surfaces in its host, produced a range of cell‐wall‐degrading enzymes. These included esterases that may be important in the depolymerization of suberin. Slow breakdown of suberin by this fungus was demonstrated.

Solving the puzzles of cutin and suberin polymer biosynthesis
Current Opinion in Plant Biology, 2012Cutin and suberin are insoluble lipid polymers that provide critical barrier functions to the cell wall of certain plant tissues, including the epidermis, endodermis and periderm. Genes that are specific to the biosynthesis of cutins and/or aliphatic suberins have been identified, mainly in Arabidopsis thaliana.

Suberin — a biopolyester forming apoplastic plant interfaces
Current Opinion in Plant Biology, 2007Suberized cell walls form physiologically important plant-environment interfaces because they act as barriers that limit water and nutrient transport and protect plants from invasion by pathogens. Plants respond to environmental stimuli by modifying the degree of suberization in root cell walls.

Cutin and suberin monomers are membrane perturbants
Journal of Colloid and Interface Science, 2004The interaction between cutin and suberin monomers, i.e., omega -hydroxylpalmitic acid, alpha, omega -hexadecanedioic acid, alpha, omega --hexadecanediol, 12-hydroxylstearic acid, and phospholipid vesicles biomimicking the lipid structure of plant cell membranes has been studied by optical and transmission electron microscopy, quasielastic light ...

Building lipid barriers: biosynthesis of cutin and suberin
Trends in Plant Science, 2008Cutin and suberin are the polymer matrices for lipophilic cell wall barriers. These barriers control the fluxes of gases, water and solutes, and also play roles in protecting plants from biotic and abiotic stresses and in controlling plant morphology.
