TaGPAT6 enhances salt tolerance in wheat by synthesizing cutin and suberin monomers to form a diffusion barrier.

Journal of Integrative Plant Biology
One mechanism plants use to tolerate high salinity is the deposition of cutin and suberin to form apoplastic barriers that limit the influx of ions. However, the mechanism underlying barrier formation under salt stress is unclear.

Suberin: A Biopolyester of Plants' Skin

Macromolecular Bioscience, 2007
AbstractSuberin is a biopolymer that acts as a barrier between plants and the environment. It is known to be a complex polyester based on glycerol and long‐chain α,ω‐diacids and ω‐hydroxyacids. How these monomeric units are assembled at a macromolecular level remains mostly unknown.

Glycerol-derived ester oligomers from cork suberin

Chemistry and Physics of Lipids, 2006
The cork suberin polyester was partially depolymerized by a methanolysis reaction catalyzed by calcium hydroxide. The methanolisate was analysed by ESI-MS/MS in the form of [M+Li](+) adduct-ions. This reaction solubilized a mixture of monomers and oligomers, including a set of glycerol-derived dimeric and trimeric esters.

Demystifying suberin

Canadian Journal of Botany, 2002
Suberin is a term used to define a specific cell wall component that occurs, for example, in phellem (cork) endodermal and exodermal cells and is characterized by the deposition of both poly(phenolic) and poly(aliphatic) domains. Historically, the poly(phenolic) domain has been likened to lignin, and while there is an element of truth to this ...

MYB24, MYB144, and MYB168 positively regulate suberin biosynthesis at potato tuber wounds during healing.

The Plant Journal
The essence of wound healing is the accumulation of suberin at wounds, which is formed by suberin polyphenolic (SPP) and suberin polyaliphatic (SPA).

Precursor biosynthesis regulation of lignin, suberin and cutin

Protoplasma, 2021
The 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 ...

WRKY9 transcription factor regulates cytochrome P450 genes CYP94B3 and CYP86B1, leading to increased root suberin and salt tolerance in Arabidopsis.

Physiologia Plantarum : An International Journal for Plant Biology, 2021
Salinity affects crop productivity worldwide and mangroves growing under high salinity exhibit adaptations such as enhanced root apoplastic barrier in order to survive under such conditions.

Suberin degradation by Rosellinia desmazieresii

European Journal of Forest Pathology, 1994
AbstractIn 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.

Linear Aliphatic Dimeric Esters from Cork Suberin

Biomacromolecules, 2006
Cork suberin was partially depolymerized by methanolysis catalyzed by calcium hydroxide. Analysis by GC-MS of the methanolysate showed suberin monomers, including glycerol and long-chain alpha,omega-diacids and omega-hydroxyacids. ESI-MS analysis of the methanolysate showed, besides the aliphatic monomers, suberin oligomers, including linear dimeric ...

Synthesis of hydrophobic biopolyesters from depolymerized Pinus radiata bark suberin

Holzforschung
The bark of Pinus radiata offers an underutilized source of high-value renewable chemicals such as extractable polyphenols and lipophilic compounds (waxes and suberin). Here, the depolymerization and extraction of suberin from P.
