Plant cutin genesis: unanswered questions
Trends in Plant Science, 2015The genesis of cutin, the main lipid polymer present in the biosphere, has remained elusive for many years. Recently, two main approaches have attempted to explain the process of cutin polymerization. One describes the existence of an acyltransferase cutin synthase enzyme that links activated monomers of cutin in the outer cell wall, while the other ...

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 ...

Alkanetriols in psilotophyte cutins
Phytochemistry, 1975Abstract The covalently bonded components of the stem cutin of Psilotum include 16-hydroxyhexadecanoic acid and substantial amounts of hexadecane-1,8,16-triol. While of generally similar composition, leaf cutin of Tmesipteris contains a mixture of hexadecanetriol isomers. The findings suggest that psilotophyte cutins evolved in a different manner

Cutin Composition of Five Finnish Berries
Journal of Agricultural and Food Chemistry, 2005The raw cutin (i.e., extractive-free isolated cuticular membrane) fraction from Finnish berries, sea buckthorn (Hippophaë rhamnoides), black currant (Ribes nigrum), cranberry (Vaccinium oxycoccos), lingonberry (Vaccinium vitis-idaea), and bilberry (Vaccinium myrtillus), was depolymerized by NaOMe-catalyzed methanolysis.

Epoxy acids in the lipid polymer, cutin and their role in the biosynthesis of cutin
Biochemical and Biophysical Research Communications, 1971Abstract In apple skin slices oleic acid-1-14C was incorporated specifically into 18-hydroxyoleic acid, 10,18-dihydroxystearic acid and 9,10, 18-trihydroxystearic acid of cutin, whereas stearic acid-1-14C was not converted into these acids. Palmitic acid-1-14C, but neither palmitoleic acid-10-14C nor palmitelaidic acid-10-14C, was converted into 16 ...

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 ...

Composition of cutin from coffee leaves
Phytochemistry, 1972Abstract The constituents of the cutin of coffee leaves have been identified using TLC, GLC and GLC-MS. Dihydroxyhexadecanoic acids comprise more than 60% of the total acids. Other compounds identified include C 16 -C 34 monobasic acids, C 14 and C 15 monohydroxymonobasic acids, 16-hydroxyhexadecanoic acid and monohydroxyhexadecane-1,16-dioic ...

The constituent acids of angiosperm cutins
Phytochemistry, 1970Abstract The composition of the cutin from the cuticles of twenty-four angiosperm leaves and fruits has been compared by GLC. The most abundant acid found in angiosperm cutin is confirmed as 10,16-dihydroxyhexadecanoic with 9,10,18-trihydroxyoctadecanoic occurring frequently and 16-hydroxyhexadecanoic less frequently.

Plant waxes consisting of very long-chain, relatively nonpolar lipid molecules are associated primarily with the cuticle which extends in a continuous sheet exterior to the walls of the epidermal cells of aerial tissues. In underground tissues, stems undergoing secondary growth, and wound healing sites, waxes are associated with the suberin matrix, a ...
