CER17/ADS4 is involved in unsaturated wax and cutin monomer production in Arabidopsis. We report n-6 monounsaturated primary alcohols (C26:1, C28:1, and C30:1 homologs) in the cuticular waxes of Arabidopsis (Arabidopsis thaliana) inflorescence stem, a class of wax not previously reported in Arabidopsis. The Arabidopsis cer17 mutant was completely deficient in these monounsaturated alcohols, and CER17 was found to encode a predicted ACYL-COENZYME A DESATURASE LIKE4 (ADS4). Studies of the… Expand
Acyl-CoA desaturase ADS4.2 is involved in formation of characteristic wax alkenes in young Arabidopsis leaves.
TLDR
It is found that Arabidopsis produces wax alkenes through a unique elongation-desaturation pathway which requires the participation of ADS4.2, which was highly expressed in young leaves, especially in trichomes, where theAlkenes are known to accumulate. Expand

KEY MESSAGE The mutations BnA1.CER4 and BnC1.CER4 produce disordered wax crystals types and alter the composition of epidermal wax, causing increased cuticular permeability and sclerotium resistance.Expand
CER16 Inhibits Post-Transcriptional Gene Silencing of CER3 to Regulate Alkane Biosynthesis1[OPEN]
TLDR
It is suggested that CER16 deficiency induces post-transcriptional gene silencing of both endogenous and exogenous expression of CER3, which is implicated in alkane biosynthesis in the cuticular wax of Arabidopsis. Expand
Compositional and transcriptomic analysis associated with cuticle lipid production on rosette and inflorescence stem leaves in the extremophyte Thellungiella salsuginea.
The plant cuticle is a complex structure composed primarily of wax and cutin, but also contains cutan, glycerolipids, phenolics, polysaccharides and proteins. The cuticle plays an importantExpand

Cutin and wax are the main precursors of the cuticle that covers the aerial parts of plants and provide protection against biotic and abiotic stresses. Long-chain acyl-CoA synthetases (LACSs) playExpand
Functional Role of Long-Chain Acyl-CoA Synthetases in Plant Development and Stress Responses
TLDR
This review provides a comprehensive analysis of LACS family enzymes including substrate specificity, tissue-specific expression patterns, and distinct subcellular localization highlighting their specific roles in lipid synthesis and degradation. Expand
Epigenetic Activation of Enoyl-CoA Reductase By An Acetyltransferase Complex Triggers Wheat Wax Biosynthesis1[OPEN]
TLDR
It is demonstrated that specific transcription factors recruit the TaADA2-TaGCN5 histone acetyltransferase complex to epigenetically regulate biosynthesis of wheat cuticular wax, which is required for triggering germination of the adapted powdery mildew pathogen. Expand
The relationship between cuticular lipids and associated gene expression in above ground organs of Thellungiella salsugineum (Pall.) Al-Shehbaz & Warwick.
TLDR
The cuticle plays a critical role as barrier between plant and environment and its adaptation to extreme environments is discussed, and the association of cuticle lipid composition and gene expression within different organs of T. salsugineum's extreme cuticle is discussed. Expand
A conserved evolutionary mechanism permits Δ9 desaturation of very-long-chain fatty acyl lipids
TLDR
The data presented here show that the conserved desaturase architecture wherein a surface residue with a single bulky side chain forms the end of the substrate binding cavity predisposes them to single amino acid substitutions that enable a switch between long- and very-long-chain selectivity.
