Function identification of Arabidopsis GPAT4 and GPAT8 in the biosynthesis of suberin and cuticular wax

Plant Science
Surface lipids in plants include cutin, cuticular wax and suberin. sn-Glycerol-3-phosphate acyltransferases (GPATs) facilitate the acylation of sn-glycerol-3-phosphate (G3P) utilizing a fatty acyl group from acyl-coenzyme A (acyl-CoA) or acyl-acyl carrier protein (acyl-ACP) as substrates for the biosynthesis of plant extracellular lipids such as ...

Molecular Cloning and Characterization of Genes Involved in Cuticular Wax Biosynthesis

1995
The surfaces of the aerial parts of plants are coated with a layer of lipids collectively known as the cuticular waxes (1,2). This first, outer barrier to the environment is thought to play an important, but as yet undefined role in the survival of the organism.

Mechanisms for elongation in the biosynthesis of fatty acid components of epi-cuticular waxes

Phytochemistry, 1999
It is known that branched-chain amino acids can serve as precursors to iso- and anteiso-branched components of epi-cuticular waxes. Keto acid deamination products of Val, Leu and Ile are thought to serve as primers which are elongated by fatty acid synthase. However, the origin of elongation carbons has not been studied directly.

Elucidating the biosynthesis of polyketides accumulating in barley (Hordeum vulgare) cuticular wax

2021
The epicuticular waxes covering the uppermost organs of the barley plant, including spikes, peduncles and flag leaf sheaths, are dominated by β-diketones and related hydroxy-β-diketones. Cultivars characterized by higher amounts of these compounds display improved resistance to water loss, therefore resulting in higher production yields.

The positional sterile (ps) mutation affects cuticular transpiration and wax biosynthesis of tomato fruits

Journal of Plant Physiology, 2011
Cuticular waxes are known to play a pivotal role in limiting transpirational water loss across primary plant surfaces. The astomatous tomato fruit is an ideal model system that permits the functional characterization of intact cuticular membranes and therefore allows direct correlation of their permeance for water with their qualitative and ...

Wax crystal-sparse leaf 3 encoding a β-ketoacyl-CoA reductase is involved in cuticular wax biosynthesis in rice

Plant Cell Reports, 2016
WSL3 encodes β-ketoacyl-CoA reductase (KCR) in rice, in a similar way to YBR159w in yeast, and is essential for VLCFA biosynthesis and leaf wax accumulation. Cuticular waxes on plant surfaces limit non-stomatal water loss, protect plants against deposits of dust and impose a physical barrier to pathogen infection.

Wax Crystal-Sparse Leaf1 encodes a β–ketoacyl CoA synthase involved in biosynthesis of cuticular waxes on rice leaf

Planta, 2008
Cuticular waxes, forming the plant/atmosphere interface of plants colonizing the terrestrial environment, are complex mixtures of very-long chain fatty acids (VLCFAs) and their derivatives. In VLCFAs biosynthesis, beta-ketoacyl CoA synthase (E.C.2.3.1.119, KCS) is the key enzyme.

Emerging Insights Into Cuticular Wax Biosynthesis and Its Response to Abiotic Stresses

Plant, Cell & Environment
ABSTRACT Cuticular waxes, together with cutin, form a hydrophobic barrier that protects the plants against various biotic and abiotic stresses. The past decade has seen remarkable progress in deciphering the wax biosynthesis and transport, however, the continuous discovery of wax‐defective mutants and the development of diverse ...

Molecular and chemical characterization of genes involved in maize cuticular wax biosynthesis

2018
The primary surfaces of the arial parts of plants, and the surfaces of reproductive organs are covered by an extra cellular layer called the cuticle. The cuticle provides the foremost protection to the plant in order to adapt to the terrestrial environment. The cuticle composed of a biopolymer (cutin), which is embedded in a coating of cuticular waxes.
