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 ...

BODYGUARD is required for the biosynthesis of cutin in Arabidopsis
New Phytologist, 2016Summary The cuticle plays a critical role in plant survival during extreme drought conditions. There are, however, surprisingly, many gaps in our understanding of cuticle biosynthesis. An Arabidopsis thaliana T‐DNA mutant library was screened for mutants with enhanced transpiration using a simple condensation spot method.

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.

The constituent acids of gymnosperm cutins
Phytochemistry, 1972Abstract The constituent cutin acids of selected species of gymnosperms, a lycopod and a fern have been determined by GLC-MS of the methyl ester trimethylsilyl ethers. A large number of novel cutin acids has been found. Of particular significance is the occurrence of 9,16-dihydroxyhexadecanoic acid in certain species.

Hydrolysis of Cutin by PET‐Hydrolases
Macromolecular Symposia, 2010AbstractFunctionalisation of synthetic polymers by using enzymes has been recently demonstrated. The major advantage of enzymes over chemical processes lies in their surface specific and endo‐wise mode of action. Surface hydrophilisation of PET with lipases and cutinases leads to a dramatic increase of the surfacial acid and hydroxyl group content ...

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 ...

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.

Biopolyester Membranes of Plants: Cutin and Suberin
Science, 1980Cutin, a biopolyester composed of hydroxy and epoxy fatty acids, is the barrier between the aerial parts of higher plants and their environment. Suberin, a polymer containing aromatics and polyesters, functions as a barrier in underground parts, wound surfaces, and a variety of internal organs.

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.

Insights into the Sorption Properties of Cutin and Cutan Biopolymers
Environmental Science & Technology, 2008Plant cuticles have been reported as highly efficient sorbents for organic compounds. The objective of this study was to elucidate the sorption and desorption behavior of polar and nonpolar organic compounds with the major structural components of the plant cuticle: the biopolymers cutin and cutan.
